Answer:

\displaystyle \frac{1}{5} \\ \frac{211}{1500} \\ \frac{11}{300}

Step-by-step explanation:

\displaystyle \frac{1,8}{9} = 0,2 = \frac{1}{5}

Greatest Common Divisor [GCD]: 9

\displaystyle \frac{2,11}{15} = \frac{211}{1500}

Greatest Common Divisor [GCD]: 1⁄100

\displaystyle \frac{3,3}{90} = \frac{11}{300}

Greatest Common Divisor [GCD]: 3⁄10

I am joyous to assist you.

BRAINLIESTTTT ASAP!!!!
Lesechka [4]

Answer:  (B)  y - 3 = 2(x - 1)

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

The Point-Slope formula is: y - y₁ = m(x - x₁)   where

  • m is the slope
  • (x₁, y₁) is any point on the line

It is given that the slope (m) is 2 and a point on the line (x₁, y₁) is (1, 3), so the equation is: y - 3 = 2(x - 1)

The sample consisted of 50 night students, with a sample mean GPA of 3.02 and a standard deviation of 0.08, and 25 day students,
bulgar [2K]

Answer: The test statistic is t= -0.90.

Step-by-step explanation:

Since we have given that

n₁ = 50

n₂ = 25

\bar{x_1}=3.02\\\\\bar{x_2}=3.04\\\\\sigma_1=0.08\\\\\sigma_2=0.06

So, s would be

s=\sqrt{\dfrac{n_1\sigma_1^2+n_2\sigma_2^2}{n_1+n_2-2}}\\\\s=\sqrt{\dfrac{50\times 0.08^2+25\times 0.06^2}{50+25-2}}\\\\s=0.075

So, the value of test statistic would be

t=\dfrac{\bar{x_1}-\bar{x_2}}{s(\dfrac{1}{n_1}+\dfrac{1}{n_2})}\\t=\dfrac{3.02-3.04}{0.074(\dfrac{1}{50}+\dfrac{1}{25})}\\\\t=\dfrac{-0.04}{0.074(0.02+0.04)}\\\\t=\dfrac{-0.04}{0.044}\\\\t=-0.90

Hence, the test statistic is t= -0.90.
