Choose the expression that is NOT equivalent to the following expression:
45y + 99
5(9y + 19.8)
9(5y + 11)
2(22.5y + 49.5)
4(11y + 22)
Answer:
4(11y +22)
Step-by-step explanation:
5(9y+19.8) =45y+99
9(5y+11)=45y+99
2(22.5y+49.5)=45y+99
4(11y+22)=44y+88
you must expand the numbers to get the total
for example you multiply 5×9y and 5×19.8 in a

If your roll a six sided die what is the probability of getting a 2 or a 6
(A) 1/3
(B) 1/4
(C) 1/6
(D) 2/3
Answer:
(A)1/3
Step-by-step explanation:
probability of getting a 2 = 1/6
probability of getting a 6 = 1/6
so the probability of getting a 2 or a 6
=(probability of getting a 2+probability of getting a 6)
=(1/6+1/6)
=2*(1/6)
=1/3
RESEARCH STUDY 11.2: Dr. Bloedorn is a health psychologist who researches nutrition. She is curious as to whether a new drink additive will help people consume fewer calories during a meal. The drink additive is a white, odorless, tasteless powder that a person can add to any drink. She collects a random sample of 63 overweight students on campus and measures the calories they eat during lunch using a bomb calorimeter. She then gives this additive to the same 63 participants to use at dinner and measures how many calories they eat (again using the bomb calorimeter). Imagine that Dr. Bloedorn finds no difference between the calories consumed with the drink additive and without. This is known as
Answer:
This is known as null effect
Step-by-step explanation:
A null effect is the outcome of an experiment that does not give the effect or result expected. Although an experiment with a null effect has a result, however the result of the experiment does not support the hypothesis
An example of a null result that remains importantly useful is the Michelson-Morley experiment from that partly made possible the formulation of special relativity theory

Find the value of x.
Answer:
x= 128*
Step-by-step explanation:
180*-52*=128*
Answer:
x = 128
Step-by-step explanation:
well we know that for a polygon, the interior angles always add up to 360.
One angle is 52, and since the other two have squares it means that they are a perfect 90 degree angle. add those up to get 232, and then subtract 232 from 180 to get 128
Write an exponential model given the points ( 7, 12 ) and ( 8, 25 ). Round to the nearest hundredth.
Answer:
The exponential model is [tex]y = 0.07\cdot e^{0.73\cdot x}[/tex].
Step-by-step explanation:
The exponential model can be modelled by the following mathematical expression:
[tex]y = A\cdot e^{B\cdot x}[/tex] (1)
Where:
[tex]x[/tex] - Independent variable.
[tex]y[/tex] - Dependent variable.
[tex]A, B[/tex] - Coefficients.
If we know that [tex](x_{1}, y_{1}) = (7,12)[/tex] and [tex](x_{2}, y_{2}) = (8,25)[/tex], then we get the following system of equations:
[tex]A\cdot e^{7\cdot B} = 12[/tex] (2)
[tex]A\cdot e^{8\cdot B} = 25[/tex] (3)
If we divide (3) by (2), we calculate the value of [tex]B[/tex]:
[tex]e^{B}=\frac{25}{12}[/tex]
[tex]B = \ln \frac{25}{12}[/tex]
[tex]B \approx 0.734[/tex]
And by (2), we determine the value of [tex]A[/tex]:
[tex]A = 12\cdot e^{-7\cdot B}[/tex]
[tex]A = 0.0704[/tex]
The exponential model is [tex]y = 0.07\cdot e^{0.73\cdot x}[/tex].
Find the value of x. 120
Answer:
x = 25
Step-by-step explanation:
2x + 70 = 120 {Subtract 70 from both sides}
2x = 120 -70
2x = 50 {divide both sides by 2}
x = 50/2
x = 25

Answer:
C
Step-by-step explanation:
The length of arc AC (L) is calculated as
L = circumference of circle × fraction of circle
= 2πr × [tex]\frac{150}{360}[/tex]
= 2π × 12 × [tex]\frac{5}{12}[/tex]
= 2π × 5
= 10π ≈ 31.42 → C

On Monday, Homeroom 104 turned in 64 canned goods. This is 17 less than the number of canned goods Homeroom 106 turned in. Select the equation that could be used to find the number of canned goods c Homeroom 106 turned in on Monday.
Multiple choice question.
A)
c−64=17
B)
64−c=17
C)
c+64=17
D)
17+c=64
Answer:
i think its B) because its a subtraction equation
The equation that represents the total number of canned goods in Homeroom 106 on Monday will be 64 - c = 17. Then the correct option is B.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The act of converting a specified statement into an expression or equation is known as a sentence-to-equation transformation.

Math help please answer question a and b ( show work please)
Answer:
a) 24 degrees
b) 50 degrees
Step-by-step explanation:
part a : use sine-1
sine-1 = [tex]\frac{opposite}{hypotenuse}[/tex]
sine-1 = [tex]\frac{17}{42}[/tex]
sine-1 = 0.405
missing angle = 23.89
round to the nearest degree = 23.89 = 24
part b : use cosine-1
cos-1 = [tex]\frac{adjacent}{hypotenuse}[/tex]
cos-1 = [tex]\frac{16}{25}[/tex]
cos-1 = 0.64
missing angle = 50.208
round to the nearest degree = 50.208 = 50

Step-by-step explanation:
To find the diameter of a circle, you multiply the radius (the radius is the distance from the outside of the circle to the middle) by 2.
Ex: the first one has 6m as the radius. So you would multiply the 6 by 2. Which would be 12.
The radius is half of the diameter. So for number 8, the answer would be 2.
