Answer:

2.86

Step-by-step explanation:

So I'm pretty sure we don't want the probability, just the zscore

to find the zsore subtract the mean and divide by the standard deviation

(93-87)/2.1= 2.86

Answer:

Step-by-step explanation:

If cost is directly proportional to speed, then the equation for this is

£ = ks, where k is the constant of proportionality. We need to solve for this first.

400 = k4 so

100 = k. Now we will use that k value in the next equation to find the cost of a 6GHz processor:

£ = (100)(6) so

£ = 600

Answer:

(x - 4)(x - 2)²

Step-by-step explanation:

x³ - 8x² + 20x - 16

x³ - 4x² + 4x - 4x² + 16x - 16

x(x² - 4x + 4) - 4(x² - 4x + 4)

(x - 4)(x² - 4x + 4)

(x - 4)(x² - 2x - 2x + 4)

(x - 4)(x(x - 2) - 2(x - 2))

(x - 4)(x - 2)(x - 2)

(x - 4)(x - 2)²

(x - 4)(x - 2)²

Answer:

AC ≈ 11.0 cm

Step-by-step explanation:

Using Pythagoras' identity in Δ CDE and Δ ADE

CE² + DE² = DC²

CE² + 7² = 8²

CE² + 49 = 64 ( subtract 49 from both sides )

CE² = 15 ( take the square root of both sides )

CE = [tex]\sqrt{15}[/tex]

-------------------------------------------------------

AE² + DE² = DA²

AE² + 7² = 10²

AE² + 49 = 100 ( subtract 49 from both sides )

AE² = 51 ( take the square root of both sides )

AE = [tex]\sqrt{51}[/tex]

Then

AC = AE + CE = [tex]\sqrt{15}[/tex] + [tex]\sqrt{51}[/tex] ≈ 11.0 cm ( to the nearest tenth )

==========================================================

Explanation:

If you apply the distance formula, you should find that triangle DEF has the following side lengths

Those distances are exact. The sqrt(50) approximates to 7.071

Since 7.071 is the longest side, we'll make c = sqrt(50)

Then we have a = 5 and b = 5

Note that a^2+b^2 = 5^2+5^2 = 50 while c^2 = (sqrt(50))^2 = 50

Both a^2+b^2 and c^2 are equal to 50.

That means a^2+b^2 = c^2 is a true equation for the a,b,c values mentioned.

By the converse of the pythagorean theorem, we have shown that triangle DEF is a right triangle.

Side notes:

Answer:

right

Step-by-step explanation:

we should find the distance of

DE

EF

FD

for DE

D(2,3) = (x1,y1)

E(5,7) = (x2,y2)

disatnce = [tex]\sqrt{(x2 - x1)^2 + (y2 - y1)^2}[/tex]

=[tex]\sqrt{(5-2)^2 + (7-3)^2}[/tex]

=[tex]\sqrt{3^2 + 4^2}[/tex]

=[tex]\sqrt{16+9}[/tex]

=[tex]\sqrt{25}[/tex]

=5 units

for EF

E(5,7) = (x1 , y1)

F(9,4) = (x2 , y2)

distance =[tex]\sqrt{(x2 - x1)^2 + (y2 - y1)^2}[/tex]

=[tex]\sqrt{(9-5)^2 + (4-7)^2}[/tex]

=[tex]\sqrt{(4)^2 + (-3)^2}[/tex]

=[tex]\sqrt{16 + 9}[/tex]

=[tex]\sqrt{25}[/tex]

=5 units

for DF

D(2,3) = (x1 , y1)

F(9,4) = (x2 , y2)

diatance =[tex]\sqrt{(x2 - x1)^2 + (y2 - y1)^2}[/tex]

=[tex]\sqrt{(9-2)^2 + (4-3)^2}[/tex]

=[tex]\sqrt{7^2 + 1^2}[/tex]

=[tex]\sqrt{49 + 1}[/tex]

=[tex]\sqrt{50}[/tex]

=[tex]5\sqrt{2}[/tex]

It is a right angle triangle .

to prove right angle triangle

sum of square of two smaller sides = sum of square of longest side

5^2 + 5^2 =[tex](5\sqrt{2})^2[/tex]

25 + 25 = 52 *2

50 + 50

hence proved.

Answer:

x = 70

Step-by-step explanation:

The two angles are same side interior angles and same side interior angles add to 180

45+ (2x-5) = 180

Combine like terms

2x +40 = 180

Subtract 40 from each side

2x+40-40 =180-40

2x =140

Divide by 2

2x/2 = 140/2

x = 70

Answer:

x=70

Answer:

x=16

Step-by-step explanation:

angle TVQ = angle VWS (if they are parallel they can be said as corresponding angles)

5x-22 = 3x+10

5x-3x = 10+22

2x = 32

x = 32/2

x = 16

Answer:

B

Step-by-step explanation:

If PQ and RS are to be parallel, then

∠ TVQ = ∠ VWS ( corresponding angles ) , that is

5x - 22 = 3x + 10 ( subtract 3x from both sides )

2x - 22 = 10 ( add 22 to both sides )

2x = 32 ( divide both sides by 2 )

x = 16

For PQ and RS to be parallel then x = 16

Answer: baby 5

Step-by-step explanation:

5 + 5 = baby 5 BOOM BABY ITS THAT SIMPLE :)

Answer:

61 degrees

Step-by-step explanation:

Considering angle <GJI and <IKD, these two angles are corresponding angles. Recall that corresponding angles are equal hence,

m<GJI = m<IKD = 119 degrees

Again

m<GJI and m<AJG are on a straight line at a point. Recall that the sum of angles on a straight line is 180 degrees. Hence

m<GJI + m<AJG = 180

119 + m<AJG = 180

m<AJG = 180 - 119

= 61 degrees

Hope this help!!!

Have a nice day!!!

Answer:

X = 132

Step-by-step explanation:

The sum of two interior angles in a triangle is equal to an exterior angle that is supplementary to the third interior angle therefore

x = 46 + 86

x = 132

Answer:

The measures of exterior angle is 132° .

Step-by-step explanation:

We know that the sum of interior angle is equal to the sum of exterior angle of triangle.

86° + 46 ° = x

combine like terms

132° = x

Answer:

a^8

Step-by-step explanation:

When dividing exponents simply subtract the exponents and keep the base the same

So a^10 / a^2

Subtract the exponents

10-2=8

And keep the base

We would get a^8

f-¹f(10)=10

Answer:

Solution given:

f(x)=3x-2

let

y=3x-2

interchanging role of x and y

x=3y-2

y=[tex]\frac{x+2}{3}[/tex]

so

f-¹(x)=[tex]\frac{x+2}{3}[/tex]

now

f(10)=3*10-2=28

now

f-¹f(10)=f-¹(28)=[tex]\frac{28+2}{3}[/tex]=10

the person below isn't giving the right answer choice did you ever get the answer for this question please comment me the answer cuz they clearly don't see the answer choice

Answer:

below

Step-by-step explanation:

you can find the distance between the y values for each x value and if it comes out to be an even increase/decrease you know it is linear

Answer:

It does not form a linear equation.

Step-by-step explanation:

For this question, you should check that they all have the same gradient.

To work out the gradient, use [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex].

Using the top 2 rows, this gives [tex]\frac{-1--3}{-2--6}[/tex], or [tex]\frac{2}{4}[/tex], simplified to [tex]\frac{1}{2}[/tex]. This means for every increase in x by 1, y increases by [tex]\frac{1}{2}[/tex].

Between the first 2 rows, x increases by 4 and y by 2 (half of 4), so it is true.

Between the second and third rows, x increases by 2 and y by 2 (which isn't half of 2). This is false, meaning this does not form a linear equation.

**This question involves solving linear equations using gradients, which you may want to revise. I'm always happy to help!

(x), (x-2), (x-5), (x-5), (x-7) and (x-9) are NOT zeros, they are FACTORS. The zeros are 0, 2, 5, 5, 7, and 9. Since 5 is listed twice it is said to be a zero of multiplicity 2. To find a polynomial with those zero, we start by setting x equal to each zero: x=0, x=2, x=5, x=5, x=7, and x=9. Then we subtract the zero on the right from both sides of each of those 6 equations: x-0=0, x-2=0, x-5=0, x-7=0, x-9=0 Then we use the principle that equals multiplied by equals gives equals. So we multiply all the left sides together and all the right sides together. (Multiplying all the right sides together just gives 0.) (x-0)(x-2)(x-5)(x-5)(x-7)(x-9) = 0 And since x-0 is just x, we have (x)(x-2)(x-5)(x-5)(x-7)(x-9) = 0 Those are the factors you gave. But again, the zeros are 0,2,5,5,7,9

Sorry if I'm wrong I'm in 8 grade I learned it in this year

Answer:

$18

Step-by-step explanation:

Given the following data;

Number of friends = 8

Total expense = $120

Tip = 20%

To find how much each friend would pay?

First of all, we would determine the amount of tip.

Tip = 20/100 * 120

Tip = 2400/100

Tip = $24

New balance = total expense + tip

New balance = 120 + 24

New balance = $144

Next, we find how much each friend would pay using the mathematical expression;

Each paid = 144/8

Each paid = $18
