If he flipped the coin 100 times and got 50 heads, then the answer would be 0.5 (since 50/100 = 1/2 = 0.5). I think you might be mixing theoretical probability with empirical probability.

In this case, he got 28 heads out of 75 flips
so 28/75 = 0.373333... where the 3's repeat forever
This rounds to 0.37

That's why the answer is actually choice A

Hawick is 1515 miles south of Abbotsford, and Kelso is 1717 miles east of Abbotsford. What is the distance from Hawick to Kelso?

Mashcka [7]

Answer:

As per the statement:

Hawick is 15 miles south of Abbotsford, and Kelso is 17 miles east of Abbotsford.

Let H represents Hawick , A represents Abbotsford and K represents Kelso

See the diagram as shown below:

Distance of AH = 15 miles

Distance of AK = 17 miles.

We have to find the distance HK:

Using Pythagoras theorem;

$\text{Hypotenuse side}^2 = \text{Adjacent side}^2 + \text{opposite side}^2$

then;

$\text{HK}^2 = 15^2+17^2 = 225 + 289 = 514$

or

$HK = \sqrt{514} =22.671581$ miles.

Therefore, the distance from Hawick to Kelso( to the nearest tenth place) is 22.6 miles

11cm

(6) + 5

11cm

therefore it is a square when x = 6 because the sides are all equal

Find the nonpermissible replacement for b in b - 1/ b + 7

This will be -7 because this would make the denominator b + 7 = 0.

Jaqleen can unload a grocery truck twice as fast as Marco. Together, they can unload the truck in 5 hours. How long would it tak

amm1812

Jaqleen unloads a truck in x hours and Marco takes 2x hours.

Working together (x*2x) / (x+2x) = 5 hours

2x^2 / 3x = 5 Multiplying both sides by 3x equals 2x^2 -15x = 0

x = 7.5 hours

So Jaqleen takes 7.5 hours and Marco takes 15 hours

Double-Check (7.5 * 15) / (7.5 + 15) = 112.5 / 22.5 equals

5 hours Correct!!
