Answer:

D and E

Step-by-step explanation:

He divides the number line into 6 equal parts. Meaning that 6/6 would be the whole, and the denominator would be 6, or a simplified version of that.

so you got the generic 1/6, 2/6, 3/6, 4/6 and 5/6, which is D

but E is the simplified version of the previous one

2/6 simplifies into 1/3

4/6 simplifies ino 2/3

So technically E is correct as well, just a simplified version of D, thus your answer choices being D and E.

An equation of a line through (-1,4) which is perpendicular to the line y = 4x + 1 and the slope is -1/4 what is the y-intercept

Ilya [14]

The equation of the line is $y=-\frac{1}{4}x+\frac{15}{4}$

The y - intercept of the equation is $\frac{15}{4}$

Explanation:

Given that the equation of the line is $y=4 x+1$ and the slope is $m=-\frac{1}{4}$

<u>Equation of the line:</u>

The equation of the line can be determined using the formula,

$y-y_1=m(x-x_1)$

Substituting the point (-1,4) and the slope $m=-\frac{1}{4}$ , we get,

$y-4=-\frac{1}{4}(x+1)$

Simplifying, we get,

$y-4=-\frac{1}{4}x-\frac{1}{4}$

$y=-\frac{1}{4}x-\frac{1}{4}+4$

$y=-\frac{1}{4}x+\frac{15}{4}$

Thus, the equation of the line is $y=-\frac{1}{4}x+\frac{15}{4}$

<u>y - intercept:</u>

The y - intercept of the equation is value of y when x = 0

Hence, substituting x = 0 in the equation $y=-\frac{1}{4}x+\frac{15}{4}$ , we get,

$y=-\frac{1}{4}(0)+\frac{15}{4}$

$y=\frac{15}{4}$

Thus, the y - intercept of the equation is $\frac{15}{4}$

It is believed that approximately 75% of American youth now have insurance due to the health care law. Suppose this is true, and

prohojiy [21]

Answer:

Step-by-step explanation:

Binomial distribution can be used in this case

P(x=r) nCr×q^n-r×q^r

n =15

p = 75/100= 0.75

q= 1-p = 0.25

a) The distribution of x is discrete

b) the probability that x is at least 10

= probability of x greater than or equal to 10 = P(x= 10) +P(x = 11) + P(x=13) +P(x=14) +P(x =15)

P(x= 10) =15C10×0.25^5×0.75^10=0.1651

P(x = 11) =15C11×0.25^4×0.75^11=0.2252

(x=12) =15C1×0.25^3×0.75^12=0.2251

(x=13) =15C13×0.25^2×0.75^13=0.1559

(x=14)=15C14×0.25^1×0.75^14=0.0668 (x=15)=15C15×0.25^0×0.75^15=0.0134

probability of x greater than or equal to 10 = P(x= 10) +P(x = 11) + P(x=13) +P(x=14) +P(x =15)= 0.1651+ 0.2252+0.2251+0.1559+0.0668+0.0134

= 0.8381

The probability that X is at most 10 =

1-probability of x is greater than or equal to 11

= 1- (0.2252+0.2251+0.1559+0.0668+0.0134 =1-0.673

=0.327

d)P(x=10)=0.1651

Mean = np =15*0.75=15

Standard deviation = npq=15×0.25=2.8125

Variance =2.8125^2=7.91
