Answer:
x=75
Step-by-step explanation:
[tex]We\ are\ given\ that:\\AD\ is\ the\ altitude\ of\ \triangle ABC\\Hence,\\ADC=90[As\ altitudes\ intersect\ the\ base\ side\ at\ 90]\\Hence,\\As\ ADC=(x+15)\ and\ ADC=90\\x+15=90\\x=90-15\\x=75[/tex]
This is only the value of x in terms of AD being an altitude, and is independent off the sides.
Which table does not represent a function
Answer:
B.
Step-by-step explanation:
B. table B has 2 y values for one x, and that makes it not a function but a relation / equation.
The table shows the heights h(in feet) of a sponge t seconds after it was dropped by a window cleaner on top of a skyscraper
See attachment for the scatter plot created using the graphing calculator
The best fitting quadratic model for the data is h = -16t^2 + 280The sponge will hit the ground after 4.18 secondsA. Use a graphing calculator to create a scatter plotThe table of values is given as
Time, t 0 1 1.5 2.5 3
Height, h 280 264 244 180 136
Next, we enter the above values in a graphing calculator to create the scatter plot
See attachment for the scatter plot created using the graphing calculator
B. Find the best fitting quadratic model for the data
From the graphing calculator, we have
h = -16t^2 + 280
C. Use your model to predict when the sponge will hit the groundThis means that
h = 0
So, we have
-16t^2 + 280 = 0
Divide through by -16
So, we have
t^2 - 17.5 = 0
This gives
t^2 = 17.5
Take the square roots
t = 4.18
Hence, the sponge will hit the ground after 4.18 seconds

Ed is a mid segment for this triangle solve for X
I will give a brainless if a kind human being could answer this problem and explain it this is due in 15 mins and I’m confused :(
I will give a Brainlist also :)
Answer:
Step-by-step explanation:
What you are being told is that 3x - 7 is twice as big as x. You can see that because ST (for example) is cut into 2 equal parts. So is UT (cut into two equal parts). So the parts of the Big Triangle (SUT) are twice as Big as the parts of the small triangle DET
So multiply x by 2
3x - 7 = 2x Add 7 to both sides
3x - 7 + 7 = 2x + 7
3x = 2x + 7 Subtract 2x from both sides
3x-2x = 7
x = 7
The Aluminum Association reports that the average American uses 56.8 pounds of aluminum in a year. A random sample of 51 households is monitored for one year to determine aluminum usage. If the population standard deviation of annual usage is 12.3 pounds, what is the probability that the sample mean will be more than 59 pounds _________.
a) 0.1003
b) 0.3997
c) 0.6003
d) 0.8997
e) 0.0003
Answer:
A: 0.1003
Step-by-step explanation:
We are given;
Population mean; μ = 56.8
Population size; n = 51
Population standard deviation; σ = 12.3
We want to find; P(x > 59)
We will use the z-score formula.
z = (x - μ)/(σ/√n)
z = (59 - 56.8)/(12.3/√51)
z = 1.28
From z-distribution table attached, we have; P(z < 1.28) = 0.8997
Thus;
P(z > 1.28) = 1 - 0.8997 = 0.1003
1. What value of x makes the equation 3x - 6 = 9 true?
Answer:
5
Step-by-step explanation:
this is basic algebra so it's important to understand this concept now. you need to combine like terms so 3x-6=9 becomes 3x=15 (you add the 6 to add like terms). You then divide the 3 from 3x on both sides to get x=5
The value of x makes the equation 3x - 6 = 9 true is: x = 5.
Here, we have,
given that,
the equation is: 3x - 6 = 9
so have,
3x-6=9
We need to combine like terms
=> 3x = 9 + 6
(we add the 6 to add like terms).
becomes, => 3x=15
we then divide the 3 from on both sides
=> 3x/3 = 15/3
we get
=> x=5

ANHL player's labor negotiating committee is to be selected from 8 player representatives from the Eastern Conference and 7 player representatives from the Western Conference. Find the probability of selecting 3 Eastern Conference representatives and 2 Western Conference representatives.
a. 1/ 3003
b. 1/3
c. 56/143
d. 140/429
Answer:
21 / 143
Step-by-step explanation:
Given that:
Number of Eastern conference reps = 8
Number of western conference rep = 7
Probability of selecting 3 from Eastern reps and 2 from western reps
Probability = required outcome / Total possible outcomes
Total possible outcomes:
selection to be made = 3+ 2 = 5
Total Number of players = 8 +7 = 15
Total possible outcomes
Using combination formula :
nCr = n! / (n-r)!r!
15C5 = 15! / 10!5! = (15 * 14 * 13 * 12 * 11) / (5*4'3*2*1) = 360360 / 120 = 3003
Total possible outcomes = 3003
Required outcome :
8C3 * 7C2
8C3 = 56 ; 7C2 = 21
8C3 * 7C2 = 56 * 21 = 1176
required outcome / Total possible outcomes
= 1176 / 3003
= 21 / 143
Using the hypergeometric distribution, it is found that the probability is:
c. 56/143
The players are selected from the sample without replacement, hence, the hypergeometric distribution is used.
Hypergeometric distribution:
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes. N is the size of the population. n is the size of the sample. k is the total number of desired outcomes.In this problem:
There are 15 representatives, hence [tex]N = 15[/tex]8 are from the Eastern Conference, hence [tex]k = 8[/tex]Sample of 5, hence [tex]n = 5[/tex].The probability is P(X = 3), hence:
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}[/tex]
[tex]P(X = 3) = h(3,15,5,8) = \frac{C_{8,3}C_{7,2}}{C_{15,5}} = 0.3916[/tex]

What is monthly compounding?
Monthly compounding means that the interest is computed every month, in essence, the interest in January, March and May would be 1% divided by 12 months in a year whereas the interest in February, April, would be 3% divided 12 months making a year.
FV=PV*(1+r1)*(1+r2)*(1+r3)+(1+r4)*(1+r5)

Approximately 54% of mathematics students do their homework on time. In a class of 250 students, what is the mean, variance, and standard deviation if we assume normality and use the normal distribution as an approximation of the binomial distribution?
A) Mean = 135 Variance = 62 Standard Deviation = 8B) Mean = 53 Variance = 62 Standard Deviation = 8C) Mean = 54 Variance = 8 Standard Deviation = 62D) Mean = 135 Variance = 8 Standard Deviation = 62
Answer:
A) Mean = 135 Variance = 62 Standard Deviation = 8
Step-by-step explanation:
Given that :
Proportion (p) = 54%
Sample size (n) = 250
Using Normal approximation :
Mean = np
Mean = 250 * 0.54 = 135
Variance = npq ; q = 1 - p = 1 - 0.54 = 0.46
Variance = (250 * 0.54 * 0.46) = 62.1 = 62
Standard deviation = √variance = √62.1
Standard deviation = 7.8803553 = 8

Find the equation for the line graph below
Write an absolute value equation that has the solutions x=8 and x=18
.
Answer:
|x - 13| = 5
Step-by-step explanation:
Think of absolute value as a distance. For example, |5| can be written as |5 - 0| = 5 since the distance between 5 and zero on the number line is 5. Also, |-5| which is the same as |-5 - 0| is also 5 since the distance between -5 and zero on the number line is 5.
Since you want an absolute value equation with solutions 8 and 18, think of which number is the same distance from both 8 and 18 on the number line? Find the average of 8 and 18, (8 + 18)/2 = 13. 13 is the same distance from both 8 and 18. 13 is 5 units away from both 8 and 18. Now you need an equation that is looking for the numbers x which are 5 units distance from 13.
|x - 13| = 5
