We need a common denominator before we subtract. Both numbers go into 8. 5/8 stays as 5/8 and 1/2 becomes 4/8

Now we can subtract: 5/8 - 4/8
All we have to do is subtract the numerators (5 - 4) and keep the same denominator.

5 - 4 = 1

The answer is <span>1/8.</span>

Find the number that makes 4:12 equivalent to 28:__.
guapka [62]

Answer:

84

Step-by-step explanation:

We can set up a proportion using fractions.

\frac{4}{12} = \frac{28}{x}

Now, let's cross multiply by multiplying 12 and 28 then dividing by 4.

12\cdot28=336\\\\336\div4=84

Hope this helped!

As a store manger you would like to find out the average time it takes to unload the truck which delivers the merchandise for yo
Georgia [21]

Answer:

The upper boundary of the 95% confidence interval for the average unload time is 264.97 minutes

Step-by-step explanation:

We have the standard deviation for the sample, but not for the population, so we use the students t-distribution to solve this question.

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 35 - 1 = 35

95% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 34 degrees of freedom(y-axis) and a confidence level of 1 - \frac{1 - 0.9}{2} = 0.975([tex]t_{975}). So we have T = 2.0322

The margin of error is:

M = T*s = 2.0322*30 = 60.97

The upper end of the interval is the sample mean added to M. So it is 204 + 60.97 = 264.97

The upper boundary of the 95% confidence interval for the average unload time is 264.97 minutes

What is the value of x?
vazorg [7]

Answer:

x = 58

Step-by-step explanation:

Angle =  1/2(difference of intercepted arcs)

51 = 1/2 ( 160 -x)

Multiply each side by 2

2*51 = 160-x

102 = 160-x

Subtract 160

102 -160 = -x

-58 = -x

58 =x
