Answer:
Step-by-step explanation:
x+y=180; y+z=180
145+z=180
z= 35
y=180-35
y =145
x=180-145
x= 35
---------------------
2x-10=x+80
x=90
3y-4 =y+20
2y = 24
y = 12
Answer:
16.2
Step-by-step explanation:
because 3x2=6
I AM SOOOO SORRY IF I GET IT WRONG
Hello!
I believe the answer is 2.
I hope it helps!
Answer:
it equals to 1 ive taken the test multiple times!!!
Hot Chocolate Sales and Outside Temperatures:
(A) The scatter plot is shown below.
(B) The anomaly is located at (189, 16°F).
(C) A negative correlation exists.
(D) Sales are the dependent variable, and temperature is the independent variable.
What is Temperature?
The physical concept of temperature indicates in numerical form how hot or cold something is. A thermometer is used to determine temperature. Thermometers are calibrated using a variety of temperature scales, which historically defined various reference points and thermometric substances.
The following information is provided for hot chocolate sales and outside temperatures:
(Y) Sales Temperature (X)
100 92
213 88
830 54
679 62
209 85
189 16
1110 52
456 65
422 68
235 89
199 91
(A)
Attached below is the scatter plot.
(B)
A cluster is a group of points or values gathered in one location.
A cluster of three values between the temperatures of 80°F and 100°F may be seen on the scatter plot.
A value that differs significantly from the other values in a data set is referred to as an outlier. Either it's too little or it's too big.
In the given data collection, there is an outlier.
The anomalous value is (189, 16°F).
(C)
The scatter plot's points have a decreasing slope.
This suggests that the variables temperature and sales have a bad relationship.
There is a bad association as a result.
(D)
Dependent variables are variables that are being studied, or being kept an eye on for any changes while the other variables in the model are altered.
The variables that are changed to cause the dependent variable to vary proportionately are known as independent variables.
According to the outside temperature, the data in this case shows the sales of hot chocolate.
Sales are therefore the dependent variable, and temperature is the independent variable.
This is due to an increase in hot chocolate sales as the temperature drops.
