He wonders if the newspaper's claim holds true at his company. To find out, Dr. Huber asks a simple random sample of 125 tea-drinking employees which the prefer: green tea of black tea. Here's Dr. Huber's null hypothesis: H_0 : The proportion of all tea-drinkers at the company that prefer green tea to black tea is...

Step-by-step explanation:
Midsegment means it's the middle, or half-way . It chops the sides into even parts. The line that's the midsegment is going to be parallel to the base and half the size of the base. In other words, double the midsegment and that's equal to the base. Then, just solve for x.

Find the value of x in the trapezoid below.
124°
Answer:
56 degrees
Step-by-step explanation:
just cause
Answer:
56 degrees
Step-by-step explanation:
the total degrees in a quadrilateral is 360
and in a trapezoid the top two angles measure the same and the bottom two measure the same
so since one of the top angles is 124 the one beside it is too
add 124 and 124 you get 248
then subtract it from 360 and you get 112
divide 112 by 2 and you get 56 which is the angle of x
A rectangular swimming pool measures 50 meters in length and 25 meters in width. A scale drawing of the swimming pool will be made where 1 centimeter represents 5 meters.
Answer:
the pool would be 10 cm by 5 cm
Answer:
The scale drawing would be 10 centimeters by 5 centimeters
Step-by-step explanation:
It's 1:5
If you multiply each side by 10, you get 10:50, that shows it'd be 10cm for the length and then you do the same for the width, 5:25, to get 5cm.

Solve for x
x+4=−2
help please.
Answer:
x=-6
Step-by-step explanation:
The only thing to do is to transpose 4 and it will become negative,so-2-4=-6
Answer:
X = -6
Step-by-step explanation:
The equation is x + 4 = -2. Make the (+4) to cross over the equal sign which makes a new equation :- x = -2 - 4
Work out the new equation:-
x = -2 - 4
NOTE: -2 - 4 = -6
Therefore x = -6
GUYS I NEED HELP ASAP!!
I believe this is correct! Good luck :)
Theoretical Probability:
P(rolling a 2) = 16.7%
P(rolling a 5) = 16.7%
P(rolling 2 or 3) = 33.4%
P(greater than 4) = 33.4%
P(3 or less) = 50.1%
Experimental Probability:
P(rolling a 2) = 20%
P(rolling a 5) = 6%
P(rolling 2 or 3) = 36%
P(greater than 4) = 24%
P(3 or less) = 54%
Explanation:
Theoretical probability can be calculated based on the idea that each of the six numbers on the die has an equal chance of being rolled and all numbers' probabilities total to 100%. Experimental probability is based on the outcomes of your experiment (rolling the dice yourself).
When finding the probability of rolling a number or another number (for example, rolling a 2 or 3), just add the probabilities together (You rolled 2 ten times and 3 eight times, so the experimental probability of rolling a 2 or 3 is 18/50 = 36%)

Mathhhhhhh testtttt Add a statement, equation and concluding statement
Answer:
Charlene earns $700 per week
Kristi earns $550 per week
Sascha earns $800 per week
Step-by-step explanation:
Since Kristi earns 150 less than Charlene which is 100 less than Sascha, this is equal to the value of Sascha minus 250. We put this in the equation as s-250.
Together, they all earn $2050, so we must equal this to Charlene's value k+150, plus Kristi's value k, plus Sascha's value s.
k+150+k+s=2050
The next step here is to put the variables on one side and to put the numeric values on the other.
2k+s=1900
Like we said before, Kristi's value is equal to s-250, so we would replace k with that expression.
2(s-250)+s=1900
2s-500+s=1900
3s=2400
s= 800
We now have Sandra's weekly pay, which we can use to find the others' pay.
c= s-100
c= 800-100
c= 700
k= c-150
k= 700-150
k= 550

a gift box has dimensions of 8 1/2 inches 5 1/2 inches and 2 1/2 inches respectively how many cubes with side lengths of 1/2 inches would be needed to fill the gift box
Find the volume of each and then divide the volume of the box by the volume of the cube.
Volume of box: 8 1/2 x 5 1/2 x 2 1/2 = 116 7/8 cubic inches.
Volume of cube = 1/2^3 = 1/8 cubic inches
Number of cubes: 116 7/8 / 1/8 = 935 cubes.
