What is the reciprocal of each mixed number? (drag and drop homework)
kolezko [41]
In order to solve this, you need to make these irregular fractions. So, take the integers, 4, 5, and 1, and multiply them by the denominator, 6(Make sure to keep the denominator below them). You should now have 24/6, 30/6, and 6/6. Next, add each number to it’s corresponding fraction. You should now have 25/6, 35/6, and 11/6. Finally, just reverse them!
A 4 1/6—> 3. 6/25
B 5 5/6—> 4. 6/35
C 1 1/6 —> 1. 6/11

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.

laurens suv was detected exceeding the posted speed limit of 60 kilometers per hour , how many kilometers would she have been tr
Vlada [557]

Answer:

60 kilometers per hour (kmph) over the limit

Step-by-step explanation:

The speed limit is 60 kmph

Let's find his original rate:

We know D = RT

Where

D is the distance, in km

R is the rate, in kmph

T is the time in hours

He went 10 km in 5 minutes, so we need the time in hours, first. That would be:

5/60 = 1/12 hour

So, putting into formula, we find rate:

D = RT

10 = R(1/12)

R = 10/(1/12)

R = 10 * 12

R = 120 kmph

He was going over by:

120 - 60 = 60 kmph
