Step-by-step explanation:

Probability is the ratio of the required outcome to the total possible outcome

Total outcome = 75

Number of times target was hit (expected outcome) = 41

Pr(she will hit target)= 41/75

Next is to state in percent and u do that by multiplying the resulting fraction by 100

send help!!!! Please!! The sum of the measures of the angles from any triangle is 180 degrees. In triangle ABC, angles A and B h
Ratling [72]

Let Angle A = X

Since Angle B is the same, angle B is also X

Then angle C = X +45


Add the 3 angles together: X +X +X +45 = 3x+45


That equals 180 degrees:

3x+45 = 180

Subtract 45 from both sides:

3x = 135

Divide both sides by 3:

X = 135/3

X = 45

Angle A = 45

Angle B = 45

Angle C = 45+45 = 90

Use synthetic division to divide (x3 + 12x2 + 38x + 26) ÷ (x + 4)
KengaRu [80]
Divisor is -4
Use coefficients 1    12    38    26

Bring down 1 multiply by -4 and add to 12 =8
Multiply 8 by -4 and add to 38 = 6 
Multiply 6 by -4 and add to 26 = 2 which is the remainder

looks like     1    12    38    26
                          -4   -32   -24
                    ________________
                     1     8      6     R 2
so answer A of x squared + 8x + 6 +R2 is correct
