Histogram, because a large number of scores are reported as ranges. The correct option is A.
What is a histogram?The graphic representation of data points arranged into user-specified ranges is called a histogram. The histogram, which resembles a bar graph in appearance, condenses a data series into an intuitive visual by collecting numerous data points and organizing them into logical ranges or bins.

x = 61
Step-by-step explanation:
The two angles add to a right angle, which is 90 degrees
29+x = 90
Subtract 29 from each side
29+x-29 = 90-29
x = 61
Answer:

Step-by-step explanation:
if Y is 29 degrees and the entire angle is a 90 degree angle than x would be 61 degrees to equal a 90 degree angle

Okay, so on a grid, points Q and R are parallel to each other on the point 6, we just have to figure out how far apart they are, and to figure that out, we have to find the distance between 8 and -4 so:
8 - -4 = 8 + 4 = 12
So, the distance from point Q to point R is 12

Step-by-step explanation:
From the figure drawn, it is given that AB is parallel to DE, in ΔABC and ΔCDE, we have
∠BAC=∠DEC(Alternate angles)
∠ACB=∠DCE(Vertically opposite angles)
Thus, by AA rule, ΔABC is similar to ΔCDE.
Since the line connecting from the whales to the sharks is parallel to the line connecting from the penguins to the fish tanks, the triangles shown in the figure are similar. Using the property of similar triangles.

Answers
Answer:

Step-by-step explanation:
To find the area of a circle from the radius, you square the radius (r*r, or in this case, 6*6) and then multiply by pi. You end up with 36*3.14 or, 113.04.

1.What percent of the entire garden is devoted to roses and zinnias
2.If alyssum is planted outside of the petunias and the pattern shown in the diagram continues,
how many square feet are devoted to alyssum
Answers
Answer:
1. 30% 2. 160 square feet
Step-by-step explanation:
1.The entire area of the garden is 20x16=320 square feet
The area of the Zinnias(including roses) is 8x12 = 96 square feet
To get the percent, we have to divide the smaller number by the bigger number and multiply by 100, like 96/320x100=30%
2. The width progresses in the first rectangle by four 8 to 12, then again by four 12, 16 and again by four 16 to 20, which means that the next rectangle would have a width of 20+4=24. Doing the sale analysis for the height, we get that the increase is with 4 feet at a time or the new rectangle would have a width of 24 and height of 20, which means a total area of 480 feet. We would have to subtract all other rectangles and the new area would be 480 - (20x16) = 160 square feet
can I pls have brainliest?
Conveniently enough, the roses and zinnias are right next to each other, within the same rectangle. 12 x 8 = 96 square feet.
But we need to know what percentage that area takes place within the whole garden, so we need the garden’s area too. 20 x 16 = 320 square feet.
Now, to find the percentage of roses and zinnias within the garden. We start by putting it as a fraction, 96/320, which simplifies to 3/10. You can now easily tell that 3/10, as a percentage, is 30%
2. 160 square feet
First, you have to analyze the blueprint and see what the pattern is for every new plant added. 4 is added to the length, and 4 is added to the width. 4 would be added from 20 and 4 would be added from 16 if alyssum was added, giving 24 x 20 = 480 square feet.
We now have to subtract the old area of the garden from the new one we just calculated. And we already calculated the old garden from the last problem!
480 - 320 = 160 square feet.

30: 9
31: 180
Step-by-step explanation:
29: if c=9 then squared then it is 9 times 9 which equals 81 then a equals 1/2 which is 0.5 in fraction so we add 81 + 0.5 =81.5
30: c equals 9 which we times by 2 and equals 18 then we times 18 by a which is 0.5 and it goes back down to 9
31: b equal 15 and it is squared so we times 15 by 15 which equals 225 and then we multiply 5 times c and c is 9 so 5 times 9 is 45 and 225 minus 45 equals 180

Also use 3.14 as pi, and the top part is cut off a little bit, but it still counts as a full semi circle. Please help me.
Answers
Answer:
The continuous closed line that makes the boundary of a two-dimensional shape is known as the perimeter. It’s easy to work out the perimeter of a shape with straight edges, such as a square, because you simply add the lengths of each edge together. A different formula is required to work out the perimeter of a semi circle (a circle cut in half), because it consists of a curved edge as well as a straight edge. That formula is
Step-by-step explanation:
P = \frac{1}{2} πd + dP=

where d is the diameter of the semi circle.

P = \frac{1}{2} πd + dP=

Pi is a circle's circumference divided by its diameter and is always the same value, 3.14.

A single die is rolled. Find the probability of rolling 2 or an odd number.
Answers
Answer:
4/6 or 2/3
Step-by-step explanation:
1/2 of the die is odd numbers so, you would add one more number which would be 4/6 or 2/3
The probability of rolling 2 or an odd number is 2/3.
What is probability?"Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one".
For the given situation,
Rolling a die s = {1,2,3,4,5,6}
⇒[tex]n(s)=6[/tex]
The event a is rolling 2 = {2}
⇒[tex]n(a)=1[/tex]
Probability of rolling 2, [tex]p(a)=\frac{n(a)}{n(s)}[/tex]
⇒[tex]p(a)=\frac{1}{6}[/tex]
The event b is rolling an odd number = {1,3,5}
[tex]n(b)=3[/tex]
Probability of rolling an odd number, [tex]p(b)= \frac{n(b)}{n(s)}[/tex]
⇒[tex]p(b)=\frac{3}{6}[/tex]
Thus probability of rolling 2 or an odd number = [tex]p(a)+p(b)[/tex]
⇒ [tex]\frac{1}{6} + \frac{3}{6}[/tex]
⇒[tex]\frac{4}{6}[/tex]
⇒[tex]\frac{2}{3}[/tex]
Hence we can conclude that the probability of rolling 2 or an odd number is 2/3.
