Answer:
Adult=58
Step-by-step explanation:
c=child, a=adult
6.4c+9.7a=1145 equation 1
c+a=149 equation 2
a=149-c modified equation 2 to isolate a
6.4c+9.7(149-c)=1145 substitute value of a from equation 1 into equation 2
6.4c+1445.3-9.7c=1145
-3.3c=-300.3
c=91
solve for a
c+a=149
91+a=149
a=58
Check answer:
6.4c+9.7a=1145
6.4(91)+9.7(58)=1145
582.40+562.60=1145
1145=1145

Answer:
x = 39
Step-by-step explanation:
The Pythagorean theorem tells you the sum of the squares of the sides of a right triangle is the square of the hypotenuse.
x² +80² = 89²
x² = 89² -80² = 7921 -6400 = 1521
x = √1521

Answer: C/ The third one
Step-by-step explanation:
Two functions are shown below.
f(x) = 1/3 (3)^x
g(x) - 2x + 4
What is the largest integer value of x such that f(x) < g(x)?
Answer: 3
Step-by-step explanation:
Given
[tex]f(x)=\dfrac{1}{3}3^x[/tex]
[tex]g(x)=2x+4[/tex]
For [tex]f(x)<g(x)[/tex] to be true, the domain is given by observing the graph of two i.e. [tex]x\in (-1.981,3.117)[/tex]. In this range [tex]g(x)[/tex] is greater than [tex]f(x)[/tex].
From the above domain largest integer that can satisfy the condition is 3.
AB is the midsegment of AXYZ and PQ is the midsegment of XAB. What is the relationship in length between PQ and YZ? O PQ = 1/8 Y Z O PQ = 1/2YZ O PQ = 1/4Y Z O PQ = 1/3YZ
Answer:
third option: PQ = 1/4(YZ)
Step-by-step explanation:
By the Midsegment Theorem, a midsegment is 1/2 the side across it. Using this, we can say:
In triangle XYZ, AB = 1/2(YZ)
And in triangle XAB, PQ = 1/2(AB)
We can substitute AB into the second equation to get:
PQ = 1/2(1/2(YZ))
PQ = 1/4(YZ)
This is the third option.

jack and clint are running backs on rival college football teams. the table below shows the number of yards they have ran in each of their first five games of a season. how many yards would clint need to run in his next game to average the same number of yards as jack?
Answer:
Clint would have to run 127 yards next game to average the same number of yards as Jack.
Step-by-step explanation:
First, we find the boys' averages by adding all their yards and then dividing by the number of games.
For Jack, we get 490 yards in total, which we divide by 5, the number of games. We get a 98 yard average.
For Clint, we get 461 yards in total, which we divide by 5, the number of games. We get a 92.2 yard average.
We know Clint wants to average 98 yards at the end of the next game. That would make 6 games total. We can multiply 98 x 6 to get the total number of yards for a 98 yard average in 6 games. We get 588 yards in total. Clint already ran 461 yards in total, so we can subtract that from 588. We have 127 yards left. We now know that Clint needs to run 127 yards in the next game for a 98 yard average.
The number of yards that client needs to run in his next game to average the same number of yards as jack will be 127.
What is mean?The mean is the average of a data set. Mean gives us an idea of that how small the amount of overall data have.
In other words, the mean is the foundation of the deviation of data from all data sets.
Mean = sum of data / Number of data
The average of Jack = (123 + 87 + 108 + 80 + 92)/5 = 98
The average of Clint = (88 + 101 + 96 + 92 + 84)/5 = 92.2
To make this average 98 let's say Clint's score in the next game is x.
Mean = (88 + 101 + 96 + 92 + 84 + x)/6 = 98
(92.2 x 5 + x) = 98 x 6
x = 127
Hence"Clint needed to add 127 to be mean as same as Jack".

we need to find that whether it is a proportional or not
So here we can say that proportional relationship would be expressed in the form of
y = kx
And, k represent the constant
Therefore
y = kx equivalent to Y = 10x

Triangle ABC is graphed in the coordinate plane with vertices A(1, 1); B(3, 4) and C(- 1, 8) as shown in the figure.
Answer:
(-4,-2)
Step-by-step explanation:
B(3,4)
x=3 , y=4
(3-7,4-6)
(-4,-2)
Transformation involves changing the position of a shape.
The coordinates of B after the translation is (-4,-2)
The vertices are given as:
[tex]\mathbf{A =(1,1)}[/tex]
[tex]\mathbf{B =(3,4)}[/tex]
[tex]\mathbf{C =(-1,8)}[/tex]
The translation rule is given as:
[tex]\mathbf{(x-7,y-6)}[/tex]
So, the coordinates of B' is calculated using:
[tex]\mathbf{(x,y) \to (x-7,y-6)}[/tex]
This gives
[tex]\mathbf{(3,4) \to (3-7,4-6)}[/tex]
[tex]\mathbf{(3,4) \to (-4,-2)}[/tex]
Rewrite as:
[tex]\mathbf{B' = (-4,-2)}[/tex]
Hence, the coordinates of B after the translation is (-4,-2)

PLEASE Hurry If f(x)=7x2−2 and g(x)=2(x−7)2 , which is an equivalent form of f(x)−g(x) ? A 5x2−100 B 5x2+28x−100 C 5x2+14x−51 D 3x2+56x−198
Answer:
5x^2 +28x - 100
Step-by-step explanation:
f(x)=7x^2−2 and g(x)=2(x−7)^2
First simplify g(x)
g(x) = 2 ( x-7)(x-7) = 2( x^2 - 7x -7x +49) = 2(x^2 -14x +49) = 2x^2 -28x +98
Now f(x) - g(x)
f(x) - g(x) = 7x^2−2 - (2x^2 -28x +98)
Distribute the minus sign
= 7x^2−2 - 2x^2 +28x -98
Combine like terms
= 5x^2 +28x - 100

Write an addition equation or a subtraction equation (your choice!) to describe the diagram.
Which of the following equations describes the line shown below? Check all
that apply.
Answer:
B. y = 2x - 2
E. [tex] y + 4 = 2(x + 1) [/tex]
F. [tex] y - 6 = 2(x - 4) [/tex]
Step-by-step explanation:
The equation of the line can be found using either the point-slope equation or the slope-intercept equation.
✔️Equation of the line in point-slope using the slope and the coordinates of the point (4, 6):
Slope = m = change in y/change in x
Using (4, 6) and (-1, -4),
m = (-4 - 6)/(-1 - 4)
m = -10/-5
m = 2
Substitute m = 2, and (a, b) = (4, 6) into the point-slope equation form [tex] y - b = m(x - a) [/tex]
Thus:
[tex] y - 6 = 2(x - 4) [/tex]
✔️Equation of the line in point-slope using the slope and the coordinates of the point (-1, -4):
Slope = m = 2
Substitute m = 2, and (a, b) = (-1, -4) into the point-slope equation form [tex] y - b = m(x - a) [/tex]
Thus:
[tex] y - (-4) = 2(x - (-1)) [/tex]
[tex] y + 4 = 2(x + 1) [/tex]
✔️Equation of the line in slope-intercept form, y = mx + b
Where,
m = slope = 2
b = y-intercept = -2 (the point where the line intercepts the y-axis)
Thus, substitute m = 2 and b = -2 into y = mx + b
y = 2x + (-2)
y = 2x - 2

Suppose you conduct a hypothesis test based on a sample where the sample size is n = 50, and arrive at a p-value of 0.08. You then refer back to your notes and discover that you made a careless mistake, the sample size should have been n = 500. Will your p-value increase, decrease, or stay the same? Explain.
Answer:
Decrease
Step-by-step explanation:
The Pvalue is used to measure the level or decide if a particular research claim is significant or not. The sample size also plays a role in the Pvalue of a statistical analysis. Larger sample sizes tend to prove the significance of the claim. Using the Pvalue approach, the significance of a claim is examined by the and established by small P values. Therefore, an initial Pvalue of 0.08 obtained using a sample size of 50. The Pvalue will most likely witness a further decrease in the Pvalue if the sample size is increased to 500 as this would move the claim closer to being significant.
