Answer:

≈ 12

Step-by-step explanation:

To estimate, we'll round these mixed numbers to the nearest whole number, then multiply. Let's start with 4 1/3. 4 1/3 is <em>closest</em> to 4, since 1/3 is smaller than 1/2. Then, we can look at 2 3/4. This mixed number is <em>closest</em> to 3, since 3/4 is greater than 1/2.

Now, the two numbers we have are 4 and 3. What is 4 × 3? Well, that's pretty simple - the answer is 12. So, 4 1/3 × 2 3/4 ≈ 12. Hopefully that's helpful! :)

The mean speed of vehicles along a stretch of highway is 56 mph with a standard deviation of 4 mph. You

Elenna [48]

The corresponding z score for speed of 62 mph, 47 mph, and 56 mph is 1.5, -2.25 and 0 respectively.

<h3>Z score</h3>

Z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:

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

Where x is raw score, μ is mean, σ is standard deviation

Given that:

σ = 4, μ = 56, hence

for x = 62:

$z=\frac{62-56}{4 } =1.5$

for x = 47:

$z=\frac{47-56}{4 } =-2.25$

for x = 56:

$z=\frac{56-56}{4 } =0$

The corresponding z score for speed of 62 mph, 47 mph, and 56 mph is 1.5, -2.25 and 0 respectively.
