Answer:
1.388
Step-by-step explanation:
2 7/9 / 2 =
7/9 = 0.777

2.777 / 2 = 1.388
What is the slope-intercept form of the equation of the line that passes through the points (−3, 2) and (1, 5)?
y=34x−92
y=34x+72
y=34x−74
y=34x+174
Answer:
y = 3/4x + 17/4
Step-by-step explanation:
Step 1: Find slope m
m = (5 - 2)/(1 + 3)
m = 3/4
y = 3/4x + b
Step 2: Find b
5 = 3/4(1) + b
5 = 3/4 + b
b = 17/4
Step 3: Rewrite equation
y = 3/4x + 17/4
Answer:
y = 3/4x + 17/9
Step-by-step explanation:
Find the slope:
5 - 2/ 1 - (- 3)
3/ 1 + 4
3/4
Find the y-intercept:
2 = 3/4(-3) + b
2 = -9/4 + b
17/4 = b
Put it in an equation:
y = 3/4x + 17/9

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.

CHECK IMAGE !! shawna drew this picture of a circle use vocabulary terms to explain how she could determine the distance around the circle.
— some vocab terms: RADIUS, CIRCUMFERENCE, VOLUME, DIAMETER
tip : (just sound really smart, bc i am really smart)
Answer:
the 3 cm is the radius, if you multiply the radius by 2 you get the diameter, which is 6 cm in this case. If you use the formula for the circumference of a circle (diameter x pi = circumference) (circumference is distance around the circle) you get 6 x pi = 18.85 (note: 18.85 is not exact but rounded to 2 decimal points)
So the distance around the circle is 18.85 cm
18.85 cm

The cost of the piece of granite is $137.70. What would you expect to pay for a similar piece of granite that is 108 inches by 60 inches?
Answer:
2203.20
Step-by-step explanation:
The first piece is 15 by 27 = 405 sq in. (as shown in the pic someone else posted.)
$137.70 / 405 = 34 cents per sq in\
A piece that is 108 by 60 = 6480 sq in
6480 x .34 = $2,203.20

The Graf family made two pizzas. They ate 1 and 1/8 pizza before watching a movie, and 1/2 pizza more after the movie. What is a reasonable estimate for the amount of pizza left? Tammy chose A as the correct answer. How did she get that answer?
Answer:
3/8
Step-by-step explanation:
So 1 pizza was already eat right and 1/8 was eating I'm assuming it 1/8 then 1/2 is 4/8 so add that witch is 5/8 so 5/8 - 8/8= 3/8
Answer:
There were 3/8s left
Step-by-step explanation:
1 1/8 + 1/2 = 1 5/8
2- 1 5/8= 3/8

Write this number in scientific notation.
Thank you!
Answer:To write the number 0.0000149 in scientific notation, we need to express it as a number between 1 and 10 multiplied by a power of 10.
First, we move the decimal point to the right until there is only one non-zero digit to the left of the decimal point, which gives us:
1.49 × 10^-5
Since we moved the decimal point 5 places to the right, the exponent of 10 is negative 5.
Therefore, the scientific notation of 0.0000149 is 1.49 × 10^-5.
Step-by-step explanation:
Answer:
1.49×10^-5
Step-by-step explanation:
0.0000149=1.49×10^-5
it's to the power of -5 because it's a decimal number not a whole number

Figure ABCD is shown on the coordinate plane. Suppose a graphic designer wants to dilate the figure so that the resulting image has a smaller area than figure ABCD. Describe a way the designer can achieve this type of dilation.
Answer:
Step-by-step explanation:
If the dilated image is smaller than the original, then 0<k<1.
Meaning the scale factor is less than one, but greater than zero.
You would mulitply each coordinate by this scale factor - to obtain the coordinates of the dilated figure.
Let's choose \(\frac{1}2}\).
In the original figure Point A = (-4,3) dilating by \(\frac{1}{2}\) results in A' being (-2, 1.5). When you multiply each cooordinate (-4,3) by one half.
Applying the scale factor of one half to the other coordinates - yields these results.
Point B (4,3) becomes Point B' (2, 1.5)
Point C (-4,-4) becomes Point C' (-2,-2).
Point D (4, -4) becomes Point D' (2,-2)
Answer:
K will equal something more than 0 and less than 1.
Explanation:
Multiply each side length by the same factor, a number between 0 and 1.
Part 1: How's the weather?
Investigate the weather forecast in your city.
Record the high and low temperatures that are forecast for the next 7 days in the table below. In the columns titled, Difference," record the change in temperature from the day before. To do this, subtract the previous temperature from the current temperature Be sure to use positive and negative numbers as needed! For example, if yesterday’s temperature was 70 and today’s temperature was 65, the difference is 65 – 70 = -5.

Jasmine, Abby, and Amber had $865 altogether. Jasmine spent 2/5 of her money. Abby spent $40, and Amber spent twice as much as Jasmine. If the three friends had the same amount of money left, how much money did Abby have in the beginning?
Answer:
288.333333333
Step-by-step explanation:
Me, personally am not great with math, but I can say you have to take $865 then take away $40 then decide how much they get apiece. to do that you must divide 865 from 3. afterwards you should take that number away from 865 remember that you are also taking away 40 then you have your final answer

A triangle has angles of 124°, 28°, and 28°. Explain whether or not the triangle can have its three side lengths equal to 7 units, 6 units, and 14 units.
No it cannot. There are a couple of ways to prove this. The easiest way is that we know by looking at the angles that we have an Isosceles triangle, because we have 2 angles of the same value. We know that an Isosceles triangle must have at least 2 sides of the same length, which means that this triangle cannot have the side lengths listed.
