Question is attatched
almond37 [142]

Answer:

D

Step-by-step explanation:

If you are told that the slope is 2 that means that the equation cannot be A.

The slope is the number in front of the x. So far what you know is that

y = 2x + b

b is found from the given point.

  • x = - 8
  • y = 7
  • 7 = 2*(-8) + b                 Expand the right side
  • 7 = - 16 + b                    Add 16 to  both sides
  • 7+16 = -16 + 16 + b        
  • 23 = b

answer y = 2x + 23

The answer is D

Find the equation of the line that passes through the following lines points (0,-1) and (3,12).​
Temka [501]

Answer:

y=13/3x-1

Step-by-step explanation:

k=(y2-y1) /(x2-x1)

A(0,-1) x1=0,y1=-1

B(3,12) x2=3, y2=12

k=(12-(-1))/(3-0)

k=(12+1)/3

k=13/3

y-y1=k(x-x1)

y-(-1)=13/3(x-0)

y+1=13/3*x

y=13/3*x-1

Write 7 over 10 as a percentage
Levart [38]

70%

A percentage is the same thing as a fraction with a denominator of 100. To make our current denominator change to 100, we must multiply it by 10. So, we must do the same thing to the numerator. 7 times 10 is 70, and 10 times 10 is 100. This means 7/10 equals 70/100, which is 70%.

The probability that an individual is left-handed is 0.12. in a class of 39 students, what is the probability of finding five le
Snezhnost [94]

We are given:

p = probability = 0.12<span>
n = total students = 39 </span>

x = left handers = 5<span>
u = mean = p* n = 4.68 
σ = standard dev = √ ( n*p*(1-p)) = √ ( 39 * 0.12 * 0.88 ) = 2.03</span>

 

Calculating for the z score:

z = (x – u) / σ<span>
z = (5 – 4.68) / 2.03</span>

<span>z = 0.1576 = 0.16

</span>

Using the standard tables for z, the p value is:

p value = 0.5636 = 56.36%

 

Hence there is a 56.36% chance.
