If y varies directly as x, and x=9 when y=15, find y when x=33

Answer:

Perimeter: 50.27

Area: 201.06

Step-by-step explanation:

The perimeter (circumference) is radius times pi times 2

This would be 8 times pi tomes 2 and when you do that you get 50.27

For the area you would do radius squared times pi

This would be 8 squared times pi which is 201.06

Answer:

a) 0.3333 = 33.33% probability that the low bid on the next intrastate shipping contract is below $25,000.

b) 0.1667 = 16.67% probability that the low bid on the next intrastate shipping contract is in excess of $28,000.

Step-by-step explanation:

A distribution is called uniform if each outcome has the same probability of happening.

The uniform distribution has two bounds, a and b.

The probability of finding a value lower than x is given by:

[tex]P(X < x) = \frac{x - a}{b - a}[/tex]

The probability of finding a value higher than x is given by:

[tex]P(X > x) = \frac{b - x}{b - a}[/tex]

Uniformly distributed between 23 and 29

This means that [tex]a = 23, b = 29[/tex]

(a) Find the probability that the low bid on the next intrastate shipping contract is below $25,000.

[tex]P(X < 25) = \frac{25 - 23}{29 - 23} = 0.3333[/tex]

0.3333 = 33.33% probability that the low bid on the next intrastate shipping contract is below $25,000.

(b) Find the probability that the low bid on the next intrastate shipping contract is in excess of $28,000.

[tex]P(X > 28) = \frac{29 - 28}{29 - 23} = 0.1667[/tex]

0.1667 = 16.67% probability that the low bid on the next intrastate shipping contract is in excess of $28,000.

Answer:

x + 4 = 10

Step-by-step explanation:

a number: x

a number increased by 4: x + 4

a number increased by 4 is 10: x + 4 = 10

Since 4 + x and x + 4 are the same, you are correct.

Step-by-step explanation:

Answer:

a) 0.9548

b) 0.0452

Step-by-step explanation:

Specificity of test:

The specificity of a test is the true negative rate, that is, the proportion of people without the disease that test negative.

Sensitivity of test:

The sensitivity of a test is the true positive rate, which is the proportion of people with the disease that test positive.

a. What proportion of the people who test positive for Malaria would we expect to actually have the disease?

This is the sensitivity of the test, which is of 95.48%, so the proportion if 0.9548.

b. What proportion of people who test positive for Malaria will not have the disease?

True positive rate is of 95.48%.

1 - 0.9548 = 0.0452

So the proportion of people who test positive for Malaria will not have the disease is 0.0452.

Multiplication is the process of multiplying. The correct option is D.

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.

The result of the given operation can be written as,

[tex]-2\left[\begin{array}{ccc}-3&5&1\\8&-2&3\\2&1&-4\end{array}\right][/tex]

Since for a multiplication operation, each element of the matrix is multiplied with the given term, therefore, the matrix can be written as,

[tex]= \left[\begin{array}{ccc}-3\times -2&5\times -2&1\times -2\\8\times -2&-2\times -2&3\times -2\\2\times -2&1\times -2&-4\times -2\end{array}\right][/tex]

Solving the multiplication, we will get,

[tex]=\left[\begin{array}{ccc}6&-10&-2\\-16&4&-6\\-4&-2&8\end{array}\right][/tex]

Hence, the correct option is D.

I do know the first figure is 24 square feet.

To get your answer,

Count the amount of the blocks stacked on top each other to make the length, in this case the first photo would be 3, and the width of the block, which is 8. To get the area, you would multiply the length and width together.

Answer:

2.5

Step-by-step explanation:

This is unit rate. All you have to do is 10 divided by 4.

Multiply both sides of the equation by 6

x/2*6-4*6=x/3*6

3x-24=2x

This effectively got rid of all the fractions.

Now combine liked terms.

3x-2x-24+24=2x-2x+24     I subtracted 2x from both sides and added 24 on both sides.

x=24

We can check our answers

24/2-4=8

and 24/3=8 so my answer is correct

x=24

Answer:

C. 73 and 73

Step-by-step explanation:

An isosceles triangle has two angles that are the same, that narrows it down to C and D. The question states that there is only one 34° angle so it has to be C.

Answer:

C. 73° and 73°

Step-by-step explanation:

We know that the sum of interior angles in a triangle is equal to 180° and

Isosceles triangles has two angles with same measurement

it stated in the question that exactly one angle has measure of 34°

So the other two angles must be equal for the triangle to be isosceles

180 - 34 = 146 and this divided by 2

73° and 73° is the answer.

Step-by-step explanation:

The slant height is read from the diagram as 20.1 km.

The radius is half the diameter, so is 9.0 km.

The lateral area is ...

  A = πrs = π(9.0 km)(20.1 km) ≈ 568.3 km²

Desmos uses r for a special purpose, so we have used r₁ to signify the radius of the cone. The "round" function works only to round to an integer, so special effort must be used to get rounding to 1 decimal place.

Answer:

1. c. 515 hours

2.  c. 495 hours

Step-by-step explanation:

Sample mean:

Sum of all values in the sample divided by the number of values.

1. What is the sample mean service life for sample 2?

Sample 2 has four values, which are:

525 515 505 515

So

[tex]M = \frac{525+515+505+515}{4} = 515[/tex]

The answer is given by option C.

2. What is the mean of the sampling distribution of sample means for whenever service life is in control?

3 samples, 12 total values. We find the mean of all these values. So

[tex]M = \frac{495+500+505+500+525+515+505+515+470+480+460+470}{12} = 495[/tex]

The answer is given by option C.
