3 0

Answer:

\large\boxed{12(4c+1)}

Step-by-step explanation:

How to factor expressions?

Find the G.C.F. and divide it into the terms of the expression you need to factor, like this:

48c+12=12(4c+1)}. So I took the 12 and pulled it out of both terms, obtaining 12(4c+1).

David goes into a candy store with $5.00. he buys 9 peppermints for $0.15 each, and some sour candies. each sour candy costs $0.
ANEK [815]
Step one. $5.00 - 9 peppermints
= $5.00 - $1.35
= $3.65
Step two. Figure out how many 25 cents are in $3.65.
$3.65 divided by .25
= 14.6 So David can buy 14 sour candies.

Suppose a triangle has two sides of length 14 and 14, and that the angle between these two sides is 122 degrees. What is the len
Dafna1 [17]

Suppose we have a triangle ΔABC,

Length of AB = 14

Length of AC = 14

Angle ∠BAC = 122 degree

This triangle is isosceles triangle so, angle B = angle C = (180 - 122)/2 = 29

We know the two side and one angle of triangle ABC, here we use Sine Rule.

(In trigonometry, the law of sines, sine law, sine formula, or sine rule is an equation relating the lengths of the sides of a triangle (any shape) to the sines of its angles.)

According to the law,

\frac{a}{sinA} = \frac{b}{sinB} = \frac{c}{sinC}

\frac{a}{sinA} =\frac{14}{sin29}

Solve for a

a = 24.49 option C

To construct an interval estimate for the difference between the means of two populations when the standard deviations of the tw
kobusy [5.1K]

Answer:

C. (n₁ + n₂ - 2) degrees of freedom

Step-by-step explanation:

The t-test for difference between two mean when variance are equal is:

t=\dfrac{\bar{x}_1-\bar{x}_2}{s\sqrt{\frac{1}{n_1}+\frac{1}{n_2}}}

where ,

\bar{x}_1 = Mean of Sample 1

\bar{x}_2 = Mean of Sample 2

s = standard deviation

n_1 = size of Sample 1

n_2 = size of Sample 2

 and t is Student's t-test with (n₁ + n₂ - 2) degrees of freedom.

Solve.<br> a + 1 = Vb + 1 for b.
Katarina [22]

Answer:

b = a² + 2a

Step-by-step explanation:

a + 1 = √(b + 1)

(a + 1)² = b + 1 (Square both sides)

a² + 2a + 1 = b + 1 (Expand left side)

a² + 2a = b (Subtract 1)
