Joelle ordered 12 dozen doughnuts for the honor roll
Serjik [45]

Answer:

The answer is there are 30 glazed donuts

Step-by-step explanation:

there are 12 donuts to a dozen therefore 12 * 12 = 144 donuts all together.

donuts with chocolate icing

144 \times  \frac{3}{8}  = 54

with white icing and sprinkles

144 \times \frac{1}{4}  = 36

donuts with pink icing

144 \times  \frac{1}{6}  = 24

Total donuts minus donuts with icing equal glazed donuts

144 - 54 - 36 - 24 = 30

A researcher asks random samples of residents of two separate counties as to whether they had purchased organically grown food i
Leni [432]

Answer:

2 proportions z test

The two populations are named as residents from the first county and residents from the second county.

Step-by-step explanation:

This is testing hypothesis about the difference between two proportions.

When the proportions are tested if they are the test statistic

z= ( p^1-p^2)- (p1-p2) / √p₁q₁/n₁ + p₂q₂/ n₂

where p^1 is the proportion of success in the first sample and   p^2 of size n₁   is the proportion of success in the second sample of size n₂ with unknown proportions of successes p1 and p2 respectively.

When the sample sizes are sufficiently large

z= ( p^1-p^2)- (p1-p2) / √p₁q₁/n₁ + p₂q₂/ n₂ is approximately standard normal.

The two populations are named as residents from the first county and residents from the second county.

F + 0.3 &lt; 1.7 <br><br> Graph the solution on a number line
rusak2 [61]
So we can do anything to the equation as long as we do it to both sides
f+0.3<1.7
subtract 0.3 from both sides
f+0.3-0.3<1.7-0.3
f+0<1.4
f<1.4
so f is less than 1.4 not including 1.4
a number line would have a dot that is NOT filled in on 1.4 and then from that dot, it would go in the negative direction forever (normally to the left)

number line included

An isosceles trapezoid has base angles of 45° and bases of lengths 9 and 15. The area of the trapezoid is 36 sq. units 72 sq. un
Butoxors [25]

Answer:

Area = 36 sq units

Step-by-step explanation:

An isosceles trapezoid have two triangles and probably a rectangle or a square.

To find the area, let's determine the height of the trapezoid.

The base length of one of the triangle

= (15-9))2

= 6/2 = 3

The height will be x

X /sin 45= 3 / sin 45

X= 3

The area of the trapezoid

= 1/2(a+b)h

Where a = 15

b = 9

h = 3

Area= 1/2(15+9)3

Area= 1/2 *24*3

Area= 12*3

Area = 36 sq units
