What is the mean of the high temperatures, in degrees Fahrenheit, for the week? Show your work.

DiKsa [7]

The mean is the average, so add all the numbers and divide by 7 (7 terms).

-14 is the sum, divided by 7 = -2

The mean is -2.

Can we conclude that two similar figures can also be congruent figures? Explain.

SpyIntel [72]

Answer:

No because congruent figures are equal in all dimensions whereas similar figures are not necessarily same size.

A cyclist travels a distance of 837 1/2 feet in 25 seconds. The cyclist travels at a constant rate. What is the unit rate, in fe

wel

Answer:

$\boxed{33.5 \ \text{feet/second}}$

Step-by-step explanation:

To find the unit rate, we need to find out how much distance does the cyclist travel in 1 second. For that, we need to use the unitary method. A unitary method is a method that determines the unit rate of an object.

Note: Since the cyclist travels at a constant rate, unitary method can be used.

$\rightarrow 837 \dfrac{1}{2} \ \text{feet in 25 seconds}$

$\rightarrow 837.5 \ \text{feet} = 25 \ \text{seconds}$

Divide both sides by 25:

$\rightarrow \dfrac{837.5}{25} \ \text{feet} = \dfrac{25}{25} \ \text{seconds}$

$\rightarrow 33.5 \ \text{feet} = 1 \ \text{seconds}$

$\rightarrow \boxed{33.5 \ \text{feet/second}}$

Concentric circles have radil of 4 cm and 8 cm. What is the probability that a

monitta

The probability that a grain of rice dropped onto the circles at random lands outside the circle with the 4-cm radius and inside the circle with a radius of 8 cm is $\frac{3}{4}$ or 75%.

Step-by-step explanation:

Step 1:

First, we need to calculate the areas of both circles.

The area of a circle $= \pi r^{2}$ where r is the radius of the circle.

The inner-circle has a radius of 4 cm.

The area of the inner circle $= \pi (4^{2})= 3.1415(16) = 50.264.$

The outer circle has an inner radius of 4 cm and an outer radius of 8 cm.

So its area is $\pi (R^{2} -r^{2} )$ where R is the outer radius and r is the inner radius.

The area of the outer circle $= \pi (8^{2} -4^{2})= 3.1415(64-16).$

$3.1415(48) = 150.792.$

So the inner circle has an area of 50.264 square cm and the outer circle has an area of 150.792 square cm.

Step 2:

To find the probability of an event we divide the number of favorable outcomes by the total number of outcomes.

The total number of outcomes is the area of the entire circle

$= 50.264+150.792 = 201.056$ square cm.

The number of favorable outcomes is the area of the outer circle i.e. 150.792 square cm.

The probability of the rice falling in the outer circle $=\frac{150.792}{201.056} = \frac{3}{4} = 75 \%$ .
