Find the value of x and the measure of the angle labeled 3x”.
Answer:
D is the correct one
Step-by-step explanation:
The whole angle equals 72 and the partial angle equals 45
You put
72-45= 27
So 3x=27
Then you solve this equation
3x = 27
x = 27/3
x = 9
Step-by-step explanation:
Answer:
x = 10, 3x = 30

B) Candle B is 290 millimeters tall and burns at 5 millimeters per hour
C) Candle A burns faster because it has a rate of burning that is 1 millimeter faster per hour than Candle B (coefficient in front of t)
D) 58 hours
Step-by-step explanation:
Candle A Went down 24 in 4 hours so thats 6 millimeters per hour.
A) h= 201-6t
Candle A Went down 24 in 4 hours so thats 6 millimeters per hour (how i found the coeffiecient in front of t.)
B) Candle B is 290 millimeters tall and burns at 5 millimeters per hour
(Just interpreted the given equation)
C) Candle A burns faster because it has a rate of burning that is 1 millimeter faster per hour than Candle B, although candle B is still 50% larger than candle A at the beginning of burning.
D) 290=5t
t=58 hours
It would take 58 hours for Candle B to burn down completely, from the given equation.

What is the equation of the polynomial function shown on the graph?
Answer:
-(x+4)(x+1)(x-3).
Step-by-step explanation:
Let find the roots of the polynomial function. Roots are the x intercept( what is the value of x when y=0)
The roots are -4,-1,and 3. We can represent that as
(x+4)(x+1)(x-3)
This is a negative polynomial so we will reflect it across the x axis by putting a negative sign in front of the roots.
-(x+4)(x+1)(x-3).

g A highway department is studying the relationship between traffic flow and speed. The following model has been hypothesized. where traffic flow in vehicles per hour vehicle speed in miles per hour The following data were collected during rush hour for six highways leading out of the city. Traffic Flow () Vehicle Speed () 1257 36 1329 45 1227 30 1336 50 1349 55 1124 25 a. Use the data to compute the coefficients of this estimated regression equation (to decimals). Enter negative value as negative number. (Create the variable first using Data/Transform
Answer:
ŷ = 0.1286X - 123.2175 ;
r = 0.947
r² = 0.896
Step-by-step explanation:
Given the data:
Traffic Flow, X : ____Vehicke speed ;Y()
1257 ______________36
1329 ______________45
1227 ______________30
1336 ______________50
1349 ______________55
1124 ______________ 25
The estimated regression equation using a linear regression calculator based on the data given above is given thus:
ŷ = 0.1286X - 123.2175
Where ;
y = dependent variable (vehicle speed)
x = predictor variable (traffic flow)
Slope = 0.1286
Intercept = 123.2175
The correlation Coefficient, R, obtained using the correlation Coefficient calculator is 0.9465, This depicts a very strong positive relationship between traffic flow and vehicle speed.
The Coefficient of determination, R² which is the squared value of the correlation Coefficient = 0.9465² = 0.8958 gives the proportion of explained variance ; This means about 89.5% of variation in Vehicle speed can be explained by the regression line.

Answer:
the answer of this question is
x+13+10x+13+2x-2=180
13x+24=180
13x=156
x=12
q=10.12+13
123
Answer:
P = 25
Q = 133
R = 22
Step-by-step explanation:
x + 13 + 10x + 13 + 2x - 2 = 180 add x's
13x + 13 + 13 - 2 = 180 add number's on left
13x + 24 = 180 subtract 24 from both sides
13x = 156 divide both sides by 13
x = 12
x + 13 = 12 + 13 = 25
10x + 13= 10(12) + 13 = 133
2x -2 = 2(12) - 2 = 22

Step-by-step explanation:
A recent study revealed that the average weight of babies born in the US is normally distributed with a mean of 7.5 pounds. One researcher decides to look at the age of the mother to determine if younger mothers have babies that are significantly heavier or lighter than average. The researcher collects data from 87 babies who were born to mothers between the ages of 16 and 18. The average weight for these babies was 7.3 pounds with a standard deviation of .6 pounds. Which of the following statements is relevant to the assumption of Appropriate Measurement of the Variables?
a. the standard deviation for young mothers is not expected to be different than the standard deviation in the population
b. only one baby was measured per mother
c. weights of babies are normally distributed in the population
d. the study used a sample that is different than the comparison population and measured weight on a ratio scale
Answer:
c. Weights of babies are normally distributed
Step-by-step explanation:
The research has been conducted to identify the weight of new born babies in comparison to the weight of their mother. The samples are collected from young mothers who are at age of 16 to 18. The babies average weight turned out to be 7.3 pounds. It is assumed that the weight of babies is normally distributed.
