a=1.5 a=-2

n=-1.5 n=4

Step-by-step explanation:

(a) (b) (c)

10a2+5a-30

x=-b+-√b2-4ac/2a

a=-5+-√(5)2-4(10)(-30)/2(10)

a=-5+-√25+1200/20

a=-5+-√1225/20

a=-5+√1225/20

a=1.5

a=-5-√1225/20

A population has a mean of 125 and a standard deviation of 16. A sample of 64 observations will be taken. The probability that the sample mean will be between 122.4 and 126.1 is

Answers

Answer:

0.61204

Step-by-step explanation:

μ = 125 ; σ = 16 ; n = 64

Probability that mean will be between 122.4 and 126.1

Z = (x - μ) / σ/sqrt(n)

x = 122.4

Z = (122.4 - 125) ÷ 16/sqrt(64)

Z = - 2.6 ÷ 2 = - 1.3

P(Z < - 1.3) = 0.0968

x = 126.1

Z = (126.1 - 125) ÷ 16/sqrt(64)

Z = 1.1 ÷ 2 = 0.55

P(Z < 0.55) = 0.70884

P(Z < 0.55) - P(Z < - 1.3)

0.70884 - 0.0968

= 0.61204

Step-by-step explanation:

Question:

which point is 8 units away from ( 7, 5 ) ?

Choices:

A : (0,-3 )B (15,13) C ( 7, -3 ) D ( 1, 5 )

Solution:

(7, 5) and (7, 3) have the same x-coordinate, 7.

They are both on a vertical line that passes through point (7, 0).

(7, 5) is 5 units above the x-axis.

(7, -3) is 3 units below the x-axis.

5 + 3 = 8

(7, 5) and (7, 3) are 8 units apart.

Answer: C ( 7, -3 )

Yolanda created a scatter plot of the relationship between the number of times she visited different friends each month, y, and the distance in miles of the friends from her home, x. She calculated the equation of the trend line to be y = −3.5x + 20. Use this information to predict the number of times in one month Yolanda would visit a friend who is 4 miles from her home.

Answers

Answer:

6 times

Step-by-step explanation:

y = −3.5x + 20 ; x = 4

y = -3.5(4) + 20

y = -14 + 20

y = 6

In two or more complete senteces compare the number of x-intercepts in the graph of f(x)=x^2 to the number of x-intercepts in the graph of g(x)=x^2-7. Be sure to include the transformation that occured between the parent function f(x) and its image g(x)

Answers

Answer:

Step-by-step explanation:

f(x) = x² is an up-opening parabola with vertex (0,0). There is one x-intercept, and that is the vertex.

g(x) = x²-7 is the equivalent to f(x) shifted down 7 units. Since the vertex is below the x-axis and the parabola opens upwards, it intercepts the x-axis at two points.

Step-by-step explanation:

Given

[tex]a = 5.7[/tex]

[tex]b = 9.3[/tex]

[tex]c = 14^\circ[/tex]

Required

The area of the triangle

This is calculated as:
