A multiple choice test consists of six questions, each of which has four choices. Each question has exactly one correct answer.

1 answer:

6 0

To get 4 or fewer correct, at least 2 answers have to be wrong. And the probability of that is:
3/4 x 3/4=9/16
1-9/16=probability that 4 or fewer are correct=7/16 ☺☺☺☺

Which of the following is an equation in slope-intercept form of the line that passes through the given point and with the given

Diano4ka-milaya [45]

Answer:

$y=2x-14$

Step-by-step explanation:

we know that

The equation of the line in slope intercept form is equal to

$y=mx+b$

where

m is the slope

b is the y-intercept

In this problem we have

$m=2\\point\ (9,4)$

substitute the given in the equation

$4=2(9)+b$

Solve for b

$4=18+b$

subtract 18 both sides

$4-18=b$

$b=-14$

therefore

The linear equation in slope intercept form is equal to

$y=2x-14$

Can we conclude that two similar figures can also be congruent figures? Explain.

shusha [124]

Answer:

In similar figures, the angles are congruent, even if the sides are not. Notice that one angle in each pair of figures corresponds to an angle in the other figure. They have the same shape but not the same size

Twice the larger of two consecutive integers is equal to fifteen less than three times the smaller. Find the integers.

Alexxandr [17]

Answer:

17,18

Step-by-step explanation:

let the smaller integer be "a" and the larger be "b"

Then 2b = 3a -15 ........................equ 1

but they are consecutive integers, b= a+1 ; substitute b into equ 1,thus,

2(a+1) = 3a - 15

2a + 2 = 3a-15

collect like terms,

2+15 =3a-2a

17 = a

b= a+1

b = 17+1

b=18.

The integers are 17,18
