Answer:

D

Step-by-step explanation:

We can tell that the final number must be -2 from the graph. This means we can cross off A and C. We can also tell that 2/3 must be negative since the graph curves downwards.

Editors preparing a report on the economy are trying to estimate the percentage of businesses that plan to hire

The number of randomly selected employers that would have to be contacted is 9604

<h3>How to solve for the value of n</h3>

The confidence level is 95%

1 - 0.95 = 0.05

We have to get the z value at 0.05

0.05/2 = 0.025

Using the standard normal table, the critical value at 0.025 = 1.96

We have to define the probability as P = 50% = 0.5

we have to define q = 1 - 50% = 0.5

The formula that would be used to find the value of n is given as

n = pq\frac{Zc}{E} ^2

These variables used are:

pq = variance of population

E = margin of error = 0.01

critical value = Zc = 1.96

n = 0.5*0.5 (\frac{1.96}{0.01})^2

= 0.25 * 38416

= 9604

Hence the sample space is given as 9604

There are 108 flowers. 1/9 of them bloomed. How many did not bloom? How many did?
levacccp [35]

Answer:

96 flowers did not bloom and 12 did.

Explanation:

Total flower = 108

Number of flower that bloomed

= ⅑ of the total flowers

= ⅑ of 108

= ⅑ × 108

= 108/9

= 12

So, number of flowers that did not bloom

= Total flowers - Number of flowers that bloomed

= 108 - 12

= 96

So, 96 flowers did not bloom and 12 flowers did.

PLEASE HELP On a clock, what is the angle formed by the hour hand and minute hand at 1:30? Assume the hour and minute hand each
SpyIntel [72]

Answer:

D. 135°

Step-by-step explanation:

Time is 1:30

The minute hand traveled half of full circle

The minute hand position is:

  • 360°×1/2= 180°

The hour hand traveled 1.5 hr ÷ 12 hr= 1/8 of full circle

The hour hand position is:

  • 360°×1/8= 45°

the difference between the hands:

  • 180°-45°= 135°

Choice D. 135° is the correct one
