Answer: 32
Step-by-step explanation:
una pelota se mueve con movimiento uniforme con una velocidad de 0,25 km/seg calcular la distancia que recorre si tarda en llegar en 5 segundos
La respuesta correcta es 1.25 km
Explicación:
En general, la distancia que recorre un cuerpo es igual a su velocidad multiplicada por el tiempo que dura el movimiento. Es decir que la formula general es d (distancia) = v (velocidad) x t (tiempo). En este caso sabemos que la velocidad es 0,25 km/seg y el tiempo es 5 segundos. Es decir que la distancia es igual a 0,25 km/seg x 5 seg = 1. 25 kilómetros. De acuerdo a lo anterior la distancia que recorre la pelota es de 1.25 kilómetros.

2,000 * (1/10,000) = 2,000 / 10,000 = 2 / 10 = 0.2.
700 * (4 / 10,000) = 2,800 / 10,000 = 28 / 100 = 0.28.
300 * (8 / 10,000) = 2,400 / 10,000 = 24 / 100 = 0.24.
0.2 + 0.28 + 0.24 = 0.72.

a hardware store ordered cartons of hammers at 100$ per carton and cartons wrenches at 150$ per carton if there were a total of 25 cartons in this order And the total cost of the order was 3,000$ how many cartons of hammers were ordered
Answer:
15 cartons of Hammers were ordered
Step-by-step explanation:
Cost per carton of Hammer = $100
Cost per carton of Wrenches = $150
Total Carton = 25
Total Cost = $3,000
Required
Determine the numbers of Hammer and Wrenches
Represent the hammers with H and the wrenches with W
So;
[tex]H + W = 25[/tex]
and
[tex]100H + 150W = 3000[/tex]
Make W the subject of formula in the first equation:
[tex]H + W = 25[/tex]
[tex]W = 25 - H[/tex]
Substitute 25 - H for W in the second equation
[tex]100H + 150(25 - H) = 3000[/tex]
[tex]100H + 3750 - 150H = 3000[/tex]
Collect Like Terms
[tex]100H - 150H = 3000 - 3750[/tex]
[tex]-50H = -750[/tex]
Divide both sides by -50
[tex]\frac{-50H}{=50} = \frac{-750}{-50}[/tex]
[tex]H = \frac{-750}{-50}[/tex]
[tex]H = 15[/tex]
Hence, 15 cartons of Hammers were ordered
Construct the confidence interval for the population mean mu. c = 0.90, x = 16.9, s = 9.0, and n = 45. A 90% confidence interval for mu is:______.
Answer:
The 90% confidence interval for population mean is [tex]14.7 < \mu < 19.1[/tex]
Step-by-step explanation:
From the question we are told that
The sample mean is [tex]\= x = 16.9[/tex]
The confidence level is [tex]C = 0.90[/tex]
The sample size is [tex]n = 45[/tex]
The standard deviation
Now given that the confidence level is 0.90 the level of significance is mathematically evaluated as
[tex]\alpha = 1-0.90[/tex]
[tex]\alpha = 0.10[/tex]
Next we obtain the critical value of [tex]\frac{\alpha }{2}[/tex] from the standardized normal distribution table. The values is [tex]Z_{\frac{\alpha }{2} } = 1.645[/tex]
The reason we are obtaining critical values for [tex]\frac{\alpha }{2}[/tex] instead of that of [tex]\alpha[/tex] is because [tex]\alpha[/tex] represents the area under the normal curve where the confidence level 1 - [tex]\alpha[/tex] (90%) did not cover which include both the left and right tail while [tex]\frac{\alpha }{2}[/tex] is just considering the area of one tail which is what we required calculate the margin of error
Generally the margin of error is mathematically evaluated as
[tex]MOE = Z_{\frac{\alpha }{2} } * \frac{\sigma }{\sqrt{n} }[/tex]
substituting values
[tex]MOE = 1.645* \frac{ 9 }{\sqrt{45} }[/tex]
[tex]MOE = 2.207[/tex]
The 90% confidence level interval is mathematically represented as
[tex]\= x - MOE < \mu < \= x + MOE[/tex]
substituting values
[tex]16.9 - 2.207 < \mu < 16.9 + 2.207[/tex]
[tex]16.9 - 2.207 < \mu < 16.9 + 2.207[/tex]
[tex]14.7 < \mu < 19.1[/tex]

Step-by-step explanation:
The time it takes to travel from home to the office is normally distributed with μ = 25 minutes and σ = 5 minutes. What is the probability the trip takes more than 40 minutes?
Answer:
The probability is [tex]P(X > x) = 0.0013499[/tex]
Step-by-step explanation:
From the question we are told that
The mean is [tex]\mu = 25[/tex]
The standard deviation is [tex]\sigma = 5 \ minutes[/tex]
The random number [tex]x = 40[/tex]
Given that the time taken is normally distributed the probability is mathematically represented as
[tex]P(X > x) = P[\frac{X -\mu}{\sigma } > \frac{x -\mu}{\sigma } ][/tex]
Generally the z-score for the normally distributed data set is mathematically represented as
[tex]z = \frac{X - \mu}{\sigma }[/tex]
So
[tex]P(X > x) = P[Z > \frac{40 -25}{5 } ][/tex]
[tex]P(X > x) = 0.0013499[/tex]
This value is obtained from the z-table

[tex]=\displaystyle\int_1^2(2(t+3)+4(4-2t))\sqrt{1^2+(-2)^2}\,\mathrm dt[/tex]
[tex]=\displaystyle\sqrt5\int_1^2(22-6t)\,\mathrm dt[/tex]
[tex]=\sqrt5(22t-3t^2)\bigg|_1^2=\boxed{13\sqrt5}[/tex]
I'm tempted to say the answer is B, but it doesn't seem to match up exactly. It's possible that choice contains a typo.
In a certain state, license plates each consist of 2 letters followed by either 3 or 4 digits. How many differen license plates are there that have no repeated letters or digits?
Answer:
26 × 26 × 10 × 10 × 10 = 676 , 000 possibilities
Step-by-step explanation:
There is nothing stating that the letters and numbers can't be repeated, so all 26 letters of the alphabet and all 10
digits can be used again.
If the first is A, we have 26 possibilities:
AA, AB, AC,AD,AE ...................................... AW, AX, AY, AZ.
If the first is B, we have 26 possibilities:
BA, BB, BC, BD, BE .........................................BW, BX,BY,BZ
And so on for every letter of the alphabet. There are 26 choices for the first letter and 26 choices for the second letter. The number of different combinations of 2 letters is: 26 × 26 = 676
The same applies for the three digits. There are 10 choices for the first, 10
for the second and 10 for the third:
10 × 10 × 10 = 1000
So for a license plate which has 2 letters and 3 digits, there are: 26 × 26 × 10 × 10 × 10 = 676 , 000 possibilities.
Hope this helps.
A college financial advisor wants to estimate the mean cost of textbooks per quarter for students at the college. For the estimate to be useful, it should have a margin of error of 20 dollars or less. The standard deviation of prices is estimated to be around 100 dollars. How large of a sample size needs to be used to be 95% confident, with the given margin of error?
Answer:
minimum sample size = 97
Step-by-step explanation:
Margin of error = 20
standard deviation = 100
sample size = n
standard error = 100/sqrt(n)
confidence level, alpha = 95%
Using the standard rule for 95% confidence
standard error <= sample mean [tex]\pm[/tex] 1.96 standard error, or
20 <= 1.96*100 / sqrt(n)
n >= (1.96*100/20)^2 = 9.8^2 = 96.04
=>
n >= 97

In randomized, double-blind clinical trials of Prevnar, infants were randomly divided into two groups. Subjects in group 1 received Prevnar, while subjects in group 2 received a control vaccine. Aft er the second dose, 137 of 452 subjects in the experimental group (group 1) experienced drowsiness as a side effect. After the second dose, 31 of 99 subjects in the control group (group 2) experienced drowsiness as a side effect. Does the evidence suggest that a lower proportion of subjects in group 1 experienced drowsiness as a side effect than subjects in group 2 at the αα=0.05 level of significance?
Answer:
Step-by-step explanation:
From the summary of the given data;
After the second dose, 137 of 452 subjects in the experimental group (group 1) experienced drowsiness as a side effect.
Let consider [tex]p_1[/tex] to be the probability of those that experience the drowsiness in group 1
[tex]p_1[/tex] = [tex]\dfrac{137}{452}[/tex]
[tex]p_1[/tex] = 0.3031
After the second dose, 31 of 99 subjects in the control group (group 2) experienced drowsiness as a side effect.
Let consider [tex]p_2[/tex] to be the probability of those that experience the drowsiness in group 1
[tex]p_2[/tex] = [tex]\dfrac{31}{99}[/tex]
[tex]p_2[/tex] = 0.3131
The objective is to be able to determine if the evidence suggest that a lower proportion of subjects in group 1 experienced drowsiness as a side effect than subjects in group 2 at the α=0.05 level of significance.
In order to do that; we have to state the null and alternative hypothesis; carry out our test statistics and make conclusion based on it.
So; the null and the alternative hypothesis can be computed as:
[tex]H_o :p_1 =p_2[/tex]
[tex]H_a= p_1<p_2[/tex]
The test statistics is computed as follows:
[tex]Z = \dfrac{p_1-p_2}{\sqrt{p_1 *\dfrac{1-p_1}{n_1} +p_2 *\dfrac{1-p_2}{n_2}} }[/tex]
[tex]Z = \dfrac{0.3031-0.3131}{\sqrt{0.3031 *\dfrac{1-0.3031}{452} +0.3131 *\dfrac{1-0.3131}{99}} }[/tex]
[tex]Z = \dfrac{-0.01}{\sqrt{0.3031 *\dfrac{0.6969}{452} +0.3131 *\dfrac{0.6869}{99}} }[/tex]
[tex]Z = \dfrac{-0.01}{\sqrt{0.3031 *0.0015418 +0.3131 *0.0069384} }[/tex]
[tex]Z = \dfrac{-0.01}{\sqrt{4.6731958*10^{-4}+0.00217241304} }[/tex]
[tex]Z = \dfrac{-0.01}{0.051378 }[/tex]
Z = - 0.1946
At the level of significance ∝ = 0.05
From the standard normal table;
the critical value for Z(0.05) = -1.645
Decision Rule: Reject the null hypothesis if Z-value is lesser than the critical value.
Conclusion: We do not reject the null hypothesis because the Z value is greater than the critical value. Therefore, we cannot conclude that a lower proportion of subjects in group 1 experienced drowsiness as a side effect than subjects in group 2

What are Arithmetic operations?Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.
The operator that perform arithmetic operation are called arithmetic operators .
Operators which let do basic mathematical calculation
+ Addition operation : Adds values on either side of the operator.
For example 4 + 2 = 6
- Subtraction operation : Subtracts right hand operand from left hand operand.
for example 4 -2 = 2
* Multiplication operation : Multiplies values on either side of the operator
For example 4*2 = 8
The given expression,
⇒ 2.5a - 7 - 6.8a + 11.1
Combine like terms in expression,
⇒ 2.5a - 6.8a + 11.1- 7
Apply the arithmetic operations
⇒ -4.3a + 4.1
Hence, the simplification form of given expression is -4.3a + 4.1

find the equation of a straight line joining the points (6,9) and (4,7). Please help im bad at mathematic :( and please do a calculation too.
Answer:
y = x+3
Step-by-step explanation:
First step is to find the slope
m = ( y2-y1)/(x2-x1)
= ( 7-9)/(4 - 6)
= -2 / -2
= 1
The we can put is in slope intercept form
y = mx+b where m is the slope and b is the y intercept
y = 1x+b
Putting in one of the points
9 = 1*6+b
Subtracting 6
9-6 = b
3=b
y = 1x+3
y = x+3
Answer:
[tex]\boxed{y=x+3}[/tex]
Step-by-step explanation:
Solve for slope first.
The slope can be found through 2 points.
[tex]slope=\frac{change \: in \: y}{change \: in \: x}[/tex]
[tex]slope=\frac{7-9}{4-6}[/tex]
[tex]slope=\frac{-2}{-2}[/tex]
[tex]slope=1[/tex]
Using slope-intercept form.
[tex]y=mx+b\\m=slope\\b=y \: intercept[/tex]
[tex]y=1x+b[/tex]
Let x = 6 and y = 9.
[tex]9=1(6)+b[/tex]
[tex]9-6=b[/tex]
[tex]3=b[/tex]
[tex]y=1x+3[/tex]
Bethany has $3.10 in nickels and dimes. She has a total of 44 coins. What is the value of the nickels Bethany has?
Answer:
$1.30. Is the answer to your question
Below will be the steps! :)
Step-by-step explanation:
So we know that a nickel is 5 cents and a dime is 10 cents.
Information given:
She has 3.10 in nickels and dimes.
Also in total she has 44 coins
_______________________________________________
In my calculations, there should be 18 dimes and 26 nickels
(44-18 will give you 26.... note:she has 44 coins in total)
When we multiply 26x0.05 we will get 1.30
⭐️So the answer is $1.30.⭐️
Hope this helps!
Answer:
Total value of nickels = $1.30
Step-by-step explanation:
let the number of nickels ($0.05) be "n" and the number of dimes ($0.10) be "d"
given that the total number of coins is 44, we can write :
number of nickels + number of dimes = 44 coins, or
n + d = 44 (rearranging this)
d = 44 - n --------> (eq 1)
we are also given that the total value of coins she has is $3.10.
Hence we can also write:
total value of nickels + total value of dimes = $3.10 ---------> (eq 2)
we know that the total value of nickels is the value of each nickel x number of nickels = $0.05n
Similarly, the total value of dimes is the value of each dime x number of dimes = $0.10d
if we substitute these values into eq 2, we get
0.05n + 0.10d = 3.10 --------> (eq 3)
we can now solve eq 1 and eq 3 by substitution.
substituting eq 1 into eq 3,
0.05n + 0.10d = 3.10
0.05n + 0.10(44-n) = 3.10
0.05n + 4.4 - 0.10n = 3.10
-0.05n + 4.4 = 3.10 (subtract 4.4 from both sides)
-0.05n = 3.10 - 4.4
-0.05n = -1.3 (divide both sides by -0.05)
n = -1.3 / -0.05
n = 26 (i.e she had 25 nickels)
Hence the value of nickels she has (using formula above)
= $0.05n
= $0.05 x 26
= $1.30

Answer:
C (the third table, from the second picture).
Step-by-step explanation:
First, we need to find the slope of the graph.
Two conspicuous points are (0, -3) and (2, 1).
The slope is: (1 - -3) / (2 - 0) = (1 + 3) / 2 = 4 / 2 = 2.
A: In the table, the y-values increase by 2, while the x-values increase by 4. 2 / 4 = 1 / 2 = 0.5. The slope is not the same as the graph.
B: In the table, the y-values decrease by 2, while the x-values increase by 4. -2 / 4 = -1 / 2 = -0.5. The slope is not the same as the graph.
C: In the table, the y-values increase by 4, while the x-values increase by 2. 4 / 2 = 2 / 1 = 2. The slope is the same as the graph, so C is your answer.
D: In the table, the y-values decrease by 4, while the x-values increase by 2. -4 / 2 = -2 / 1 = -2. The slope is not the same as the graph.

The loudness of s pile driver is 112dB . About how many times the sound intensity of a pile driver? round to the nearest ten
Answer:
[tex] db = 10 log_{10} (\frac{I}{I_o})[/tex]
With db =112 db, [tex]I_o =10^{-12} W/m^2[/tex] and solving for I the intensity we have:
[tex] \frac{db}{10}= log_{10} (\frac{I}{I_o})[/tex]
[tex] \frac{112}{10}= log_{10} (\frac{I}{10^{-12}})[/tex]
Now we can exponentiate with base 10 and we got:
[tex] 10^{11.2} = \frac{I}{10^{-12}}[/tex]
And solving we got:
[tex] I= 10^{-12} * 10^{11.2} = 0.158 \frac{W}{m^2} = 0.16 \frac{W}{m^2}[/tex]
Step-by-step explanation:
We knwo that the loudnes os 112 db and we want to find the intensity. So then we can use the following formula:
[tex] db = 10 log_{10} (\frac{I}{I_o})[/tex]
With db =112 db, [tex]I_o =10^{-12} W/m^2[/tex] and solving for I the intensity we have:
[tex] \frac{db}{10}= log_{10} (\frac{I}{I_o})[/tex]
[tex] \frac{112}{10}= log_{10} (\frac{I}{10^{-12}})[/tex]
Now we can exponentiate with base 10 and we got:
[tex] 10^{11.2} = \frac{I}{10^{-12}}[/tex]
And solving we got:
[tex] I= 10^{-12} * 10^{11.2} = 0.158 \frac{W}{m^2} = 0.16 \frac{W}{m^2}[/tex]

Given that:
Sound intensity of jackhammer = 0.004
Sound intensity of compactor = 0.0025
Sound intensity of jackhammer is about 1.6 times the sound intensity of a compactor
Each factor of 10 in intensity corresponds to 10dB
Pile driver with loudness of 112dB ⇒ [tex]\frac{112}{10}=11.2[/tex]
Hence, 10^11.2 = 1.58489 × 10^11
Hence, sound intensity (I) in watts per m²
I = 1.58489 × 10^11 × 10^-12
I = 1.58489 × 10-1
I = 0.158489
Comparing the intensity of pile driver and jackhammer :
Intensity of piledriver / Intensity of jackhammer
[tex]\frac{0.158489}{0.004}[/tex]
= 39.622 ≅ 40 ( to the nearest ten )
PLEASE HELP!!!!! QUICK!! THANKS
Answer:
D. [tex] y = \frac{8}{x} [/tex]
Step-by-step explanation:
The inverse variation between two variables usually takes the following equation form:
[tex] y = \frac{k}{x} [/tex]
In the equation form given above,
[tex] k [/tex] could be value of any real number
x is the explanatory variable (independet variable), while y is the response variable (dependent variable)
Therefore, [tex] y = \frac{8}{x} [/tex] , is an example of an equation that shows inverse variation between the x and y variables.
The right option is D. [tex] y = \frac{8}{x} [/tex]
