Answer:

The probability is 0.0069

Step-by-step explanation:

First thing to do here is to calculate the z-score

Mathematically;

z-score = (x-mean)/SD/√(n)

where x = 9.1 , mean = 8.4 , SD = 1.8 and n = 40

Plugging these values into the z-score equation, we have;

z-score = (9.1-8.4)/1.8/√(40) = 0.7/1.8/6.325 = 0.0615

Now, we check the standard normal table for P(z > 2.46) = 0.0069

Why is 1/2 of 2 equals one whole
algol [13]
Hey There :)

This is because one is half of two. You could also multiply 2 * 0.5= 1, 0.5 represents \frac{1}{2} and two is the whole number. This is how \frac{1}{2} of two equals one.

Jake bought 3 drawing pens for $8.07. Each pen costs the same amount. About how much did he spend for one pen? * 2 points
Marina86 [1]

Given:

Jake bought 3 drawing pens for $8.07.

Each pen costs the same amount.

To find:

How much did he spend for one pen?

Solution:

Let x be the cost of each pen. Then

Cost of three pens = 3x

Jake bought 3 drawing pens for $8.07.

3x=8.07

Divide both sides by 3.

x=\dfrac{8.07}{3}

x=2.69

Therefore, he spend $2.69 for one pen.
