Answer:

0.63043

Step-by-step explanation:

Given that :

Mean = 225

Standard deviation = 45

P(x > 210) : (x - mean) / standard deviation

P(x > 210) = (210 - 225) / 45

P(x > 210) = - 0.333

P(Z > - 0.333) = 0.63043 (Z probability calculator)

Answer:

x=121°

Step-by-step explanation:

the sum of angles in a triangle always equal 180°

that means that 22°+37°+x°=180°

so we solve the equation by isolating the variable

add 22 and 37 together

59°+x°=180°

subtract 59 from both sides

x=121°

that means that x is 121 degrees

Answer:

Step-by-step explanation:

Recall that the quantity 25^(1/2) with fractional exponent 1/2 can be rewritten in the equivalent √25.  In other words, the exponential form

25^(1/2) has the same value (outcome) as does √25.

In general, b^(1/a) is equivalent to (index a root of b).

[tex]\sqrt{23}[/tex] is the equivalent expression of [tex]23^{\frac{1}{2} }[/tex]

An expression is combination of variables, numbers and operators.

Equivalent expression is the expression whose value will be same when we simplify.

The given expression is Twenty three power one by two.

[tex]23^{\frac{1}{2} }[/tex]

By the exponential property.

Root of twenty three is expression equivalent to twenty three power of one by two.

[tex]\sqrt{23}[/tex]

Hence, [tex]\sqrt{23}[/tex] is the equivalent expression of [tex]23^{\frac{1}{2} }[/tex]

Answer:

x ≈ 14.7

Step-by-step explanation:

Assuming the triangle is right then use Pythagoras' identity.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² + 15² = 21²

x² + 225 = 441 ( subtract 225 from both sides )

x² = 216 ( take the square root of both sides )

x = [tex]\sqrt{216}[/tex] ≈ 14.7 ( to the nearest tenth )

Answer:

y-8=-7/5(x-5)

Step-by-step explanation:

find the slope by rewriting the line's equation.

5y=3-7x

5y=-7x+3

y=-7/5x +3/5

since its parallel, the slope will be the same (-7/5)

use the formula y-y1=m(x-x1) for the point (5,8)

y-8=-7/5(x-5)

rearrange in the form y=mx+b if you wish.

Answer:

Step-by-step explanation:

Answer:

a; d = 20n

Step-by-step explanation:

you can use the process of elimination and an example problem to help!

so if mason mowed 2 lawns, he'd make $40, right? now you could try each equation to see which one equals $40

a. d = 20(2) ⇒ d = 40

b. n = 20d ⇒ 2 = 20d ⇒ d = 0.1

c. d = 20 ÷ n ⇒ d = 10

d. n = 20 + d ⇒ 2 = 20 + d ⇒ d = -18

therefore, your answer would be A!

Answer:

Slope = [tex]\frac{-1}{1}[/tex] or -1

y = 6

Step-by-step explanation:

The equation given (y = 6 - x) is the same as saying

y = -1x + 6

Since we have a negative x variable and a positive 6 and would also be graphed the same. The only difference is that the second equation I just mentioned resembles the y = mx + b expression more. In this case the slope would be

Slope = [tex]\frac{-1}{1}[/tex] or -1

While the y-intercept would be

y = 6 - x

y = 6 - 0

y = 6
