What are ratios and proportions?An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. The numerical relationship between two values demonstrates how frequently one value contains or is contained within another.
Given that the number 90 is divided in the ratio 1:4:5. The division will be done as below,
x + 4x + 5x = 90
10x = 90
x = 90 / 10
x = 9
The ratio will be,
1:4:5 = 9 : ( 9 x 4 ) : ( 9 x 5 )
1:4:5 = 9: 36: 45

Answer:
Step-by-step explanation:
30/34 is .8823 or .88 of a cookie
in 3 hours, she can make 2.647 or 2.7 of a cookie
The required number of cookies made in 3 hours is 2.64.
What is Unitary method ?In order to solve a problem for two different values of a quantity, its unit value is first derived. This method is known as unitary method.
Given that,
The number of cookies made in 34 hour is 30.
Now, in order to calculate the number of cookies made in 3 hours unitary method can be used as follows,
In 34 hour the number of cookies = 30
In 1 hour the number of cookies = 30/34
Thus, in 3 hour the number of cookies = 30/34 × 3 = 2.64.
Hence, the number of cookies made with the given rate in 3 hours is 2.64.

Step-by-step explanation:
Alessandra designed an experiment where subjects tasted water from four different cups and attempted to identify which cup contained bottled water. Each subject was given three cups that contained regular tap water and one cup that contained bottled water (the order was randomized). She wanted to test if the subjects could do better than simply guessing when identifying the bottled water.Her hypotheses were H0: p=0.25H vs.H a :p>0.25H,(where ppp is the true likelihood of these subjects identifying the bottled water).The experiment showed that 20 of the 60 subjects correctly identified the bottle water. Alessandra calculated that the statistic p=20, divided by, 60, 0.3 had an associated P-value of approximately 0.0680.What conclusion should be made using a significance level of α=0.05?A) Fail to reject H0B) Reject H0, and accept HaC) Accept H0
Answer:
3434
Step-by-step explanation:
The conclusion that should be made on the question using a significance level of α=0.05 is; Option A; Fail to reject H₀
We are given the hypotheses;
Null Hypothesis; H₀; p = 0.25
Alternative hypothesis; Hₐ; p > 0.25
p^ = 0.3
p-value = 0.068
Now, we are told that the significance level is α = 0.05
Now, the law in hypotheses testing is that when the p-value is less tan or equal to the significance level, we will reject the null hypothesis but when the p-value is greater than the significance value, we fail to reject the null hypothesis(H₀)
Now, in our question the p-value of 0.068 is greater than the significance level of 0.05 and thus we will fail to reject the null hypothesis.

For 10 values denoted x, it is given that the mean equals7.4.
Find the sum of all values
Answer:
let's see what to do buddy....
Step-by-step explanation:
The mean of the 10 values denoted x equals 7.4
So we have :
[tex] \frac{x(1) + x(2) + x(3) + ... + x(10)}{10} = 7.4 \\ [/tex]
Multiply the sides of the equation by 10 :
[tex]10 \times \frac{x(1) + x(2) + x(3) + ... + x(10)}{10} = 7.4 \times 10 \\ [/tex]
After do that we have :
[tex]x(1) + x(2) + x(3) + ... + x(10) = 74 \\ [/tex]
Which means we have the sum of all values.
And we're done...

a playground is rectangular with a length of 1/2 mi if the area of the playground is 5/8 square miles what is its width and put your answer as a fraction
Answer:
b = 5/4 miles
Step-by-step explanation:
Length of a rectangular playground, l = 1/2 miles
Area of the playground, A = 5/8 square miles
We need to find the width of the playground. We know that, the area of a rectangular shape is given by :
A = l×b, here b is the width of the playground.
[tex]b=\dfrac{A}{l}\\\\b=\dfrac{\dfrac{5}{8}}{\dfrac{1}{2}}\\\\b=\dfrac{5}{4}\ \text{miles}[/tex]
So, the width of the playground is 5/4 miles.

Find the slope of the line above
Answer:
3/5
Step-by-step explanation:
Pick two points that are easy to read. pints that are easy to read are on the intersection of grid lines.
For example, pick (-2, 0) and (3, 3).
slope = rise/run
Rise is a vertical distance.
Run is a horizontal distance.
Start at (-2, 0). To go to (3, 3) by using only horizontal and vertical segments, go up 3 unit. Now go right 5 units.
The rise is 3. The runs is 5.
slope = rise/run = 3/5
Answer: 3/5
The probability density function of the time to failure of an electronic component in a copier (in hours) is f(x) for Determine the probability that
a. A component lasts more than 3000 hours before failure.
b. A component fails in the interval from 1000 to 2000 hours.
c. A component fails before 1000 hours.
d. Determine the number of hours at which 10% of all components have failed.
The question is incomplete. Here is the complete question.
The probability density function of the time to failure of an electronic component in a copier (in hours) is
[tex]f(x)=\frac{e^{\frac{-x}{1000} }}{1000}[/tex]
for x > 0. Determine the probability that
a. A component lasts more than 3000 hours before failure.
b. A componenet fails in the interval from 1000 to 2000 hours.
c. A component fails before 1000 hours.
d. Determine the number of hours at which 10% of all components have failed.
Answer: a. P(x>3000) = 0.5
b. P(1000<x<2000) = 0.2325
c. P(x<1000) = 0.6321
d. 105.4 hours
Step-by-step explanation: Probability Density Function is a function defining the probability of an outcome for a discrete random variable and is mathematically defined as the derivative of the distribution function.
So, probability function is given by:
P(a<x<b) = [tex]\int\limits^b_a {P(x)} \, dx[/tex]
Then, for the electronic component, probability will be:
P(a<x<b) = [tex]\int\limits^b_a {\frac{e^{\frac{-x}{1000} }}{1000} } \, dx[/tex]
P(a<x<b) = [tex]\frac{1000}{1000}.e^{\frac{-x}{1000} }[/tex]
P(a<x<b) = [tex]e^{\frac{-b}{1000} }-e^\frac{-a}{1000}[/tex]
a. For a component to last more than 3000 hours:
P(3000<x<∞) = [tex]e^{\frac{-3000}{1000} }-e^\frac{-a}{1000}[/tex]
Exponential equation to the infinity tends to zero, so:
P(3000<x<∞) = [tex]e^{-3}[/tex]
P(3000<x<∞) = 0.05
There is a probability of 5% of a component to last more than 3000 hours.
b. Probability between 1000 and 2000 hours:
P(1000<x<2000) = [tex]e^{\frac{-2000}{1000} }-e^\frac{-1000}{1000}[/tex]
P(1000<x<2000) = [tex]e^{-2}-e^{-1}[/tex]
P(1000<x<2000) = 0.2325
There is a probability of 23.25% of failure in that interval.
c. Probability of failing between 0 and 1000 hours:
P(0<x<1000) = [tex]e^{\frac{-1000}{1000} }-e^\frac{-0}{1000}[/tex]
P(0<x<1000) = [tex]e^{-1}-1[/tex]
P(0<x<1000) = 0.6321
There is a probability of 63.21% of failing before 1000 hours.
d. P(x) = [tex]e^{\frac{-b}{1000} }-e^\frac{-a}{1000}[/tex]
0.1 = [tex]1-e^\frac{-x}{1000}[/tex]
[tex]-e^{\frac{-x}{1000} }=-0.9[/tex]
[tex]{\frac{-x}{1000} }=ln0.9[/tex]
-x = -1000.ln(0.9)
x = 105.4
10% of the components will have failed at 105.4 hours.

The measure of DE is 10 from the given figure
Since the given trapezoid is an isosceles trapezoid, this shows that two of the sides will be equal. According to the given diagram, we can say that:
DG = EFGiven the following parameters
DG = 2x + 5
EF = 3x + 2
2x + 5 = 3x + 2
Collect the like terms
2x - 3x = 2 - 5
-x = -3
x = 3
Get the measure of DE
DE = 4x - 2
DE = 4(3) - 2
DE = 12 - 2
DE = 10
Hence the measure of DE is 10 from the given figure
