Calculate the loss on selling 50 shares of stock originally bought as 13 3/4 and sold at 12

kaheart [24]

First we multiply 50 and 13 and 3/4
13 and 3/4 could also = 13.75
sooo lets multiply
50 x 13.75 = 687.50
so $687.50 was spent on the stock
now lets fund out how much they sold them for
we multiply 12 and 50
50 x 12 = 600
now we need to find out the loss by subtracting
$687.50 - $600 =$ 87.50
so that means this company lost $87.50 :(
hope this helps :)

alisha [4.7K]

Answer:

Part a: So the number of business owners giving holiday gift to their employees from survey is 12.

Part b: p-value is 0.00003

Part c: value of p is less that a we reject the null hypothesis.

Step-by-step explanation:

Part a

number of business owners=20% x n

number of business owners= 0.2x 60

number of business owners=12

Part b

H0: p=0.46

H1: p<0.46

Here

n=60, $\hat{p}$ =0.2, p=0.46

So test statistics is given as

$z=\frac{\hat{p}-p}{\sqrt{\frac{p(1-p)}{n}}}\\z=\frac{0.20-0.46}{\sqrt{\frac{0.46(1-0.46)}{60}}}\\z=\frac{-0.26}{0.064}\\z=-4.04$

p-value is P(z<-4.04)= 0.00003

Part c

As value of p is less that a we reject the null hypothesis.

Answer:

1) add 5 to each side

2) multiply 8 by 2

+5 +5

since -5+5 =0 then thats going to go away leaving us with ×/2=3

3+5=8

×/2=8 multiply 2 by 8 since you want to find x

and the answer is ×=16
