7.

To swap a figure to 90 degrees counter clock wise turn the points from

(x,y) to (-y,x)

Let’s get your points

(-2,3) ; (-4,2) ; (-2,-4)

Swap the values and make the new x’s negotiate

(-3,-2) ; (-2,-4) ; (4,-2)

These should be the points of the new figure with is 90 degrees counterclockwise of the first one.

10.

To find x you can either:

Add 93 and 54
Or
Find the missing value of the triangle and subtract it from 180. Let’s do both

x = 93 + 54
x = 147

Or

180 - 93 - 54
33
180 - 33 = 147

x = 147

8.

First we dilate the coordinates by 0.5

(-4,6) ; (2,6) ; (2,-4) ; (-4,-4)

Basically divide each x and by by two

(-2,3) ; (1,3) ; (1,-2) ; (-2,-2)

Two units left would be to subtract two from the x values

(-4,3) ; (-1,3) ; (-1,-2) ; (-4, -2)

Add three to each y value

New coordinates:

(-4,6) (-1,6) (-1,1) (-4,1)

6.

Since these are the same circle, then we need to multiply the radius by 2 and then make the newly formed diameters equal to each other

2(6x) = 10x + 8

Multiply

12x = 10x + 8

Get x on one side

2x = 8

Divide

x = 4

Plug in 4 for an equation

2(6(4))

48

Circumference = pi * diameter

Unsure if you use 3.14 for pi

If you use 3.14 :

(3.14) (48) = 150.72

If you use pi :

Pi (48) (rounded) = 150.80

Q2. In a school, 60% of the students are girls. 50% of the girls walk to school. 20% of the boys walk to school. What percentage
Sphinxa [80]

<em>Answer:</em>

<em>38%</em>

<em>Step-by-step explanation:</em>

<em>60 percent girls</em>

<em>50 percent of girls walk</em>

<em>50 percent take the bus</em>

<em></em>

<em>40 percent boys</em>

<em>20 percent walk</em>

<em>80 percent take the bus</em>

<em></em>

<em>If there are 100 people in the school</em>

<em>60 girls</em>

<em>30 girls take the bus</em>

<em></em>

<em>40 boys</em>

<em>8 boys walk</em>

<em></em>

<em>8+30=38</em>

<em>38% of the people walk to school</em>

(2,1),(-3,1) how do you solve this I’m looking for the slope I also have to show work
shutvik [7]

Answer: 0

Step-by-step explanation:

To find the slope, you would need to use the formula m=\frac{y_2-y_1}{x_2-x_1}.

m=\frac{1-1}{-3-2} =\frac{0}{-5} =0

The slope is 0, meaning the line is horizontal.

a test consists of 10 true false questions to pass a test a student must answer at least six questions correctly if a student gu
Delicious77 [7]

Answer:

P(X \geq 6) = P(X=6) +P(X=7) +P(X=8) +P(X=9) +P(X=10)

And using the probability mass function we got:

P(X=6)=(10C6)(0.5)^6 (1-0.5)^{10-6}=0.205

P(X=7)=(10C7)(0.5)^7 (1-0.5)^{10-7}=0.117

P(X=8)=(10C8)(0.5)^8 (1-0.5)^{10-8}=0.0439

P(X=9)=(10C9)(0.5)^9 (1-0.5)^{10-9}=0.0098

P(X=10)=(10C10)(0.5)^{10} (1-0.5)^{10-10}=0.000977

And adding the values we got:

P(X\geq 6) = 0.377

The best answer would be:

D. 0.377

Step-by-step explanation:

Let X the random variable of interest, on this case we now that:

X \sim Binom(n=10, p=0.5)

The probability mass function for the Binomial distribution is given as:

P(X)=(nCx)(p)^x (1-p)^{n-x}

Where (nCx) means combinatory and it's given by this formula:

nCx=\frac{n!}{(n-x)! x!}

For this case in order to pass he needs to answer at leat 6 questions and we can rewrite this:

P(X \geq 6) = P(X=6) +P(X=7) +P(X=8) +P(X=9) +P(X=10)

And using the probability mass function we got:

P(X=6)=(10C6)(0.5)^6 (1-0.5)^{10-6}=0.205

P(X=7)=(10C7)(0.5)^7 (1-0.5)^{10-7}=0.117

P(X=8)=(10C8)(0.5)^8 (1-0.5)^{10-8}=0.0439

P(X=9)=(10C9)(0.5)^9 (1-0.5)^{10-9}=0.0098

P(X=10)=(10C10)(0.5)^{10} (1-0.5)^{10-10}=0.000977

And adding the values we got:

P(X\geq 6) = 0.377

The best answer would be:

D. 0.377
