Answer:

7 1/7

Step-by-step explanation:

For the problem:

5 /7 × 10 = ?

Convert any mixed numbers to fractions:

10 = 10

Multiply all of the numerators by each other. Do the same with the denominators and form a new fraction with these values:

5 × 10

7 × 1

50 /7

50 ÷ 7 = 7R1, therefore:

50 /7 = 7 1/7

The result is:

× 10 = 7 1/7

Help,, i'll mark as brainliest

PtichkaEL [24]

The first question would be distance from the start, as it is steadily going up as time goes on.

The second question would be distance from the end, as it is steadily going down as time goes on.

The third question would be speed, as the speed is staying stable as shown by the straight lines seen within the distance from start/end graphs being linear lines.

Plz guys step by step with answer

kotegsom [21]

Answer:

Step-by-step explanation:

You can rearrange the equation to make it: 4y=3x-2

The slope right now is 3,but that's not the answer

So you divide the whole equation by 4 (it will give you: y=3/4 x- 0.5

So from that you can see that the slope is 3/4, C

Doing research for insurance rates, it is found that those aged 30 to 49 drive an average of 38.7 miles per day with a standard

Alja [10]

Answer: 0.4302

Step-by-step explanation:

Given : Mean : $\mu=\text{38.7 miles }$

Standard deviation : $\sigma=\text{6.7 miles }$

Sample size : $n=60$

Also, these distances are normally distributed.

Then , the formula to calculate the z-score is given by :-

$z=\dfrac{x-\mu}{\sigma}$

For x=32.5

$\\\\ z=\dfrac{32.5-38.7}{6.7}=-0.925373134\approx-0.93$

For x=40.5

$\\\\ z=\dfrac{40.5-38.7}{6.7}=0.268656\approx0.27$

The p-value = $P(-0.93$

$=P(0.27)-P(-0.93)=0.6064198- 0.1761855=0.4302343\approx0.4302$

Hence, the required probability :-0.4302
