Feliz [49]

Answer:

test stat=1.7986

p value =0.0391

Step-by-step explanation:

given

n=50

d = 7.3

s d = 28.7

formula to calculate test statistic

t=\frac{d}{\frac{s d}{\sqrt{n} } }

⇒ t=\frac{7.3}{\frac{28.7}{\sqrt{50} } }

⇒t=1.7986

for 49 df and t=1.7986  ,p value can be obtained from software

p value=0.0391

Liang has a goal of walking at least 18 miles. She walks at a rate of 4 miles per hour. Which inequality can Liang use to find h
stich3 [128]

Answer:

F (4h>18)

How To Do It:

She's walking at a rate of 4 miles per hour. Which means that you would be multiplying 4 by the amount of hours Liang walks(4h). The next part of the inequality is the sign and the other value. To get this from the equation we see that it says she must walk at least 18 miles. Meaning that the 4h will always be greater than the 18 that is on the other side.

Divide both sides by -2

-2 takes out -2 and -2 divides -10 and gives 5

x > 5

Use the distance formula to determine the distance between (-8,10) and (-6,7)
hjlf

Answer:

Distance: \sqrt{13} units

Step-by-step explanation:

The distance formula is d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} where:

  • d is the distance between points (x_1,y_1) and (x_2,y_2)
  • (x_1,y_1) are the coordinates of the first point
  • (x_2,y_2) are the coordinates of the second point

We are given that:

  • (x_1,y_1)=(-8,10)
  • (x_2,y_2)=(-6,7)

To determine the value of our distance, d, we plug in our given information into the formula and solve for

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

d=\sqrt{(-6-(-8))^2+(7-10)^2}

d=\sqrt{(-6+8)^2+(-3)^2}

d=\sqrt{(2)^2+(-3)^2}

d=\sqrt{4+9}

d=\sqrt{13}

Therefore, the distance between (-8,10) and (-6,7) is \sqrt{13} units.

See the attached graph for a visual.
