Answer:
A) that’s a $.30 decrease so to find the percent you do the formula
3.50x=.30
3.50x/3.50=.30/3.50
X=.0857
.0857=8.57% so$3.20 is 8.57% of $3.50
B) $3.20 markup=18.5% and $3.50 markup is 29.6% but this depends on where you round up at and you get the answer the same way, with the formula $2.70x=.80 because $3.50-$2.70 =.80

Answer:
Step-by-step explanation:
A triangle adds up to 180 degrees. So, just add all the angles together
75 + 40 + (x+30) = 180
115 + x + 30 = 180
145 + x = 180
x = 35

In the data set below, what is the interquartile range?
23 58 58 64 76 87
Answer: IQR= 18
Step-by-step explanation:
First, you need to put the numbers in order from least to greatest, which they already are.
23, 58, 58, 64, 76,87
then, you draw an imaginary line down the middle of the numbers (between 58 and 64), and then you find the number in the middle of these. The Q1 is 58, and the Q3 is 76. In order to find the Interquartile range (IQR), you simply subtract the two.
76-58= 18
And you have your answer
Hope this helps!
Answer:
44
Step-by-step explanation:
First, we need to find the median in the data set.
It's between 58 and 64. To find the median, we add those two numbers and then divide by 2.
58 + 64 = 122
122 ÷ 2 = 61 (Mark this point in between the numbers on the data set)
median = 61
23, 58, 58, | 64, 76, 87
Now that we have the median, we have to find the upper quartile and the lower quartile in order to find the interquartile range.
Lets find upper quartile first. In order to do that, add up all the numbers to the right of the data set from the median point, then divide by 2.
64 + 76 + 87 = 227
227 ÷ 2 = 113.5
The same goes for the lower quartile (to the left).
23 + 58 + 58 = 139
139 ÷ 2 = 69.5
Lastly, to find the interquartile range, simply subtract the lower quartile from the upper quartile.
113.5 - 69.5 = 44
Therefore interquartile range = 44.

What’s j+12=25 tape diagram
An equation is a mathematical statement that shows two mathematical expressions equal.
An equation consists a variable that does not have a fixed value to it.
Given,
j+12=25
Here ‘j’ is the variable.
To find ‘j’ we just need to 12 from 25.
So, 25 - 12 = 13
Hence, now we know that ‘j’ is equal to 13.
13 + 12 = 25

Answer:

Step-by-step explanation:
if im correct the answer is D
Answer:
C
Step-by-step explanation:
3/4 w=6 solve for w
Bc.
To solve for w, you need to isolate the variable on one side of the equation.
The equation is 3/4 w = 6.
To isolate w, you need to divide both sides of the equation by 3/4.
3/4 w / 3/4 = 6 / 3/4
The left side simplifies to w, because the 3/4 on the left side cancel out.
w = 6 / 3/4
To divide by a fraction, you need to multiply by its reciprocal.
w = 6 * 4/3
The right side simplifies to 8.
w = 8
Therefore, w = 8.

Answer:
H. 95°
Step-by-step explanation:
m∠BGC is 10° smaller than m∠CGD, which means that m∠BGC is x° - 10°
m∠DGE is 25° more than m∠EGF, which means that m∠DGE is x° + 25°
The sum of all angles in a placement like this will always equal 360°
So we put all the measures of all angles on one side of thee equation and set it equal to 360*
x° + x° - 10° + 2x° + 25° + 2x° + 3x° + 30° = 360°
After combining like terms we get 9x° + 45° = 360°
After some algebra we get x = 35°
Now at the start we said that m∠DGE is x + 25°
Plug in 35° for x and we get 35° + 25°
The final answer is m∠DGE = 95°

Consider the standard form of an exponential function:
\(y=a(b)^x\)
How does changing the base number (inside the parentheses) change your graph?
Answer:
Step-by-step explanation:
Challenge 1
We have exponential decline if 0 b 1. As you move from left to right, the curve will get less steep.
If b is greater than 1, exponential growth is present, and the curve slopes upward from left to right.
Examples include exponential decline (y = 2(0.5)x) and exponential growth (y = 2(1.2)x).
Remember that b cannot be negative.
===========================================
Challenge 2
In the general template provided, enter x = 0.
y = a(b)^x
y = a(b)^0
y = a(1) (1)
y = a
When x = 0 is plugged in, the result is y = a.
The curve is therefore on the point (0,a). The y intercept appears here. It is the point when the curve veers off the y axis. The y intercept is altered if the value of "a" is altered.
Examples:
One person tosses a ball in the air from ground level, which is represented by the function f(t)=−4t2+16t Another person tosses a ball in the air from the top of a building, which is represented by the function g(t)=−16t2+64t+192 The variables of the function are represented by time in seconds and the height of the ball f(t), g(t) in feet.

Answer: Range and mean = 8 of both
variance of Set X= 4.7
variance of Set Y= 4.6
Step-by-step explanation:
Two sets of data, set X and set Y are given
a.) Range is the difference of the highest value and the lowest value,
Therefore, Range of set X = 12-4=8
Range of set Y = 12-4=8
Now, Mean of a given data set is the average of all the terms present in the given data set
Mean of set X= Σxif/n = (4+5+6+7+16+18+24)/10 = 8
Mean of set Y= (4+5+7+32+20+12)/10= 8
Therefore, both the data sets has same range and mean.
b.) Standard deviation tells about the variability of the date and is given by,
S.D= σ = √∑ ( X − μ )^2/n
S.D of set X= √(16+9+4+1+0+1+16)/10= √4.7
S.D of set Y= √(16+9+1+0+4+16)/10= √4.6
Variance is the square of S.D, that is, σ^2
Therefore, variance of set X=4.6
variance of set Y= 4.7
c.) The calculated variances of set X and set Y are 4.7 and 4.6 respectively. It implies that the data is more distributed or varied in set X than in set Y. In the other words, data in set Y is more consistent data than of set X.
