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

with white icing and sprinkles

donuts with pink icing

Total donuts minus donuts with icing equal glazed donuts

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.
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)

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
-23(3) + 1
-69 + 1
f(3)= -68
