Answer:

b=58 ( vertically opposite angle)

58+65+x=180 (Beaing straight angle)

123+x=180

x=180-123

:.x=57

65+b+c=180 (beaing straight angle)

65+58+c=180

123+c=180

c=180-123

c=57

a=65 (beaing vertically opposite angle)

answer

:.b=57

:.c=57

:.a=65

Answer:

See below.

Step-by-step explanation:

I see there are no answer choices you've provided, but in order to interpret a confidence interval correctly, you might say something like "We are 90% confident that the true difference in the mean number of drops is contained within the interval".

Judy has a sugar cone and wants to know how many cubic inches of ice cream it will hold if it is filled completely to the top of
stepladder [879]
The answer is 10.6 cubic inches.

The formula for a volume of the cone is V = 1/3 π r² h,
where:
V - the volume of the cone,
<span>r - radius of the cone base,
</span>h - height of the cone.

It is given:
h = 4.5 in
r = 1.5 in.
π = 3.14

If:
<span>V = 1/3 π r² h,
</span>Then:
V = 1/3 × 3.14 × (1.5 in)² × 4.5 in
V = 1/3 × 3.14 × 2.25 × 4.5 in³
V = 10.6 in³

Therefore, Judy's sugar cone can hold 10.6 <span> in³.</span>

Can someone help and explain how you got the answer? Thanks^^
andreyandreev [35.5K]

Answer:

C) (0,5)

Step-by-step explanation:

f(x) is y and x is x

The table is providing you with points

y-y over x-x gives you a slope of -5

Use the points and turn it into a point-slope equation and convert to y-intercept equation

y-15=-5(x+2)

y-15=-5x-10

y=-5x+5

So the y-intercept is 5 or (0,5)
