Answer:

(-18, 0).

(-14, 1).

(-22, -1).

Step-by-step explanation:

x - 4y = -18

x = -18 + 4y

Let y = 0, then x = -18 so one point is (-18, 0).

Let y = 1 then x = -18+4 = -14 so another point is (-14, 1).

Let y = -1 then x = -18 +4(-1) = -18 - 4 = -22 so another point is (-22, -1).

Answer:

2000 = 600 + 2/5x ; 3500 ft

How To Solve:

2000 = 600 + 2/5x

Combine multiplied terms into a single fraction

2000 = 600 + 2/5x

2000 = 600 + 2x/5

Subtract 600 from both sides of the equation

2000 = 600 + 2x/5

2000 - 600 = 600 + 2x/5 - 600

Simplify

Subtract the numbers

1400 = 600 + 2x/5 − 600

Subtract the numbers

1400 = 2x/5

Solution

X = 3500

What values of a and b make the equation true? sqrt(648)=sqrt(2^a•3^b)

Anuta_ua [19.1K]

ANSWER

The value of a and b are:

$a=3,b=4$

EXPLANATION

The expression given to us is

$\sqrt{648} = \sqrt{ {2}^{a} \times {3}^{b} }$

We square both sides of the equation to obtain

$648= {2}^{a} \times {3}^{b}$

We now find the prime factorization of 648 to obtain,

${2}^{3} \times {3}^{4} = {2}^{a} \times {3}^{b}$

We now compare the exponents on both sides of the equation to obtain,

$a=3,b=4$

Therefore the correct option is C

The sat scores have an average of 1200 with a standard deviation of 120. a sample of 36 scores is selected. what is the probabil

Naya [18.7K]

We first standardise $\bar{x}$ :
P(1224 > $\bar{x}$ )=P( $\frac{1224-1200}{\frac{120}{ \sqrt{36} }}$ > $\frac{\bar{x}-1200}{\frac{120}{\sqrt{36}}}$ )
which reduces to finding P(Z > 1.2) = 0.115
