Answer 1

Answer:

common denominator = 80        

3/80 and 24/30

Step-by-step explanation:

Same thing as last one, you multiply the denominators of each fraction together. 8x10=80 then multiply the fraction with the opposite denominator, 3x10=30 so 3/80 and 3x8=24 so 24/30.

Answer 2

Answer:

common denominator: 40

3/8 = 15/40

3/10 = 12/40

Step-by-step explanation:

8 x 5 = 40 and 10 × 4 = 40. This means 40 is the common denominator.

To get from 8 to 40 you multiply by 5 and so you multiply 3 by 5. This means the numerator is 15.

To get from 10 to 40 you multiply by 4 and so you multiply 3 by 4. This means the numerator is 12.

Step-by-step explanation:

A six-week fitness program was designed to decrease the time it takes retired individuals to walk one mile. At the beginning of the program, 20 randomly selected retired individuals were invited to participate, and their times to walk a mile were recorded. After the six-week program, their times to walk a mile were again recorded. Most participants saw little to no improvement in their times to walk one mile; however, a few participants saw drastic improvements in their times to walk one mile. The program director would like to perform a hypothesis test to determine if the program reduces the mean time for retired individuals to walk a mile. Which of the following statements is true?

a. Because there are 40 observations in total, the sample size is large enough to assume that the sampling distribution of the sample mean differences is approximately normal.
b. Because the walk times before and after the program are paired, a hypothesis test is not appropriate.
c. The sampling distribution of sample means can be assumed to be approximately normal because the distribution of the sample data is not skewed.
d. Because the sample size of 20 is less than 30 and the improvements in walk times in the sample data appear to be skewed, the distribution of sample means should not be assumed to be approximately normal.
e. Because the program recruited only retired individuals, the distribution of sample means should not be assumed to be approximately normal.

Answers

Answer:

c. The sampling distribution of the sample means can be assumed to be approximately normal because the distribution of the sample data is not skewed

Step-by-step explanation:

From the given data, we have;

The category of the sample = Retired individuals

The number of participants in the sample = 20

The duration of program = six-weeks

The improvement seen by most participants = Little to no improvement

The improvement seen by few participants = Drastic improvement

Therefore, given that the participants are randomly selected and the majority of the participants make the same observation of improvement in the time to walk a mile, we have that, the majority of the outcomes show little difference in walk times after the program, therefore, the distribution of the sample data is not skewed and can be assumed to be approximately normal

If Sheila rotates triangle PQR 90° counterclockwise to form triangle LMN, what is the measure of angle MNL?
A.130 °
B.100 °
C.50 °
D.30 °

Answers

Answer:

30

Step-by-step explanation:

This is a bit nasty, but you must keep the order in mind. PQR means that Q is the middle letter. M is also the middle letter. That's the easy part. What does MNL mean?

The lettering goes clockwise. MNL is the same thing as QRP. So what is R?

50 + 100 + R = 180

150 + R = 180

R = 180 - 150

R = 30

I think it's (0,3) sorry if it not

Answer:

(3, 0)

Step-by-step explanation:

The vertex point is 3 units to the right of the origin, making the x-coordinate 3, but it doesn’t move up or down, meaning that the y-coordinate is 0.

so it’s (3,0)

Btw, the vertex is the point of the parabola where it’s the minimum or maximu (minimum in this case). You answered for the y-interceptm which is where the parabola touches the y-axis.

find the probability that a randomly selected point within the circle falls in the red shaded area round to the nearest hundredth r = 4 cm 2.5 cm 3 cm 3 cm

Answers

Answer:

[tex]p\approx 0.39[/tex]

Step-by-step explanation:

We are given a circle of radius 4 cm, and a triangle inscribed within the circle with a vertical height of 6.5 cm and a base of 6 cm.

To find the probability a randomly selected point lands in the red area, we can divide the red area by the total area.

The area for a circle is given by:

[tex]A=\pi r^2[/tex]

Since the radius is 4 cm, the area of the circle or total area is:

[tex]A=\pi (4)^2=16\pi \text{ cm}^2[/tex]

The area for a triangle is given by:

[tex]\displaystyle A=\frac{1}{2}bh[/tex]

The base of the triangle is 6 cm total and the vertical height is 6.5 cm. Therefore, the area is:

[tex]\displaystyle A=\frac{1}{2}(6)(6.5)=19.5\text{ cm}^2[/tex]

The probability of landing in the red shaded area is:

[tex]\displaystyle p=\frac{\text{Red Region}}{\text{Total Region}}[/tex]

Therefore:

[tex]\displaystyle p=\frac{19.5}{16\pi}\approx 0.39=39\%[/tex]
