The predicted value of the scatter plot at x=40, according to Sandra's trend line prediction will be 130.
What is a scatter plot?A scatter plot is a form of plot or mathematical diagram that displays values for two variables for a collection of data using Cartesian coordinates. One more variable can be presented if the points are programmed.
To get the predicted value to the scatter plot at x=40, substitute the value of x as 40 in the given function of the trend line. Therefore, the value will be,
[tex]y = 3x+10\\\\y = 3(40)+10\\\\y=130[/tex]
Hence, the predicted value of the scatter plot at x=40, according to Sandra's trend line prediction will be 130.

Here is an expression 3.2 evaluate the expression when t is 4 middle school math
Answers
Answer: Answer: C. 3.2 × 10^4
Step-by-step explanation: for this case the multiplication of the values with exponent are summed, as the exponent are the 6 and -3
6 - 3 = 3
this will be the exponent of the common value which is the 10.
after you only need to multiply 8 and 4 by separate the
8 * 4 = 32.
then we only need to place the values one by one
32 × 10^3
3 is the result of the sum of the exponent.
10 is the common value.
32 is the result of the product.
if we add another zero to the multiplication we get 3.2 and exponent finish with one more zero, then we get this result
3.2 × 10^4
because of that the C is the correct answer, keep in mind that the other answers do not apply correctly the rule of the exponent, because the rest of answer give us wrong answer with final result of the exponent.

8 × 3.14 × 1/2 = 12.56 (perimeter for the half circle)
12.56 + 10 + 8 + 10 = 40.56
Answer:
Perimeter = 40.56 inches
Explanation:
The perimeter of a shape is all side lengths added up, so, we know there are sides with the lengths 10 inches, 10 inches, 8 inches, and a semicircle.
To find the perimeter of a semicircle, the formula is
C = πd/2, circumference equals pi times diameter divided by 2 OR C = πr, circumference equals pi times radius.
The diameter is 8, so, filling out the formula, it's
C = 3.14 x 8 /2
C = 25.13/2
C = 12.56
So, adding all the sides up, it's 10 in. + 10 in. + 8 in. + 12.56 in.
Therefore, the answer/perimeter/circumference is 40.56 inches.

Answers
Answer:
244140625 or 5^12
Step-by-step explanation:
When it comes to multiplication, you add exponents IF the base (the 5 at the bottom is called base) is the same answer. for example: 1^16 x 1^9, since the exponents are the same you just add the exponents (16 & 9) which is 25 or 1^25
Dividing is the same as multiplying except your subtracting with the examples, adding and subtracting is simplifying and solving, for example
14^2 + 13^3
14 * 14 = 196
13*13*13 =2,197
196+2,197 = 2,393
Same thing for subtraction
13^3 - 14^2
2,197 - 196 = 2,001

Answer:
C. The perimeter of the kiteStep-by-step explanation:
Answer A is not correct because if the kite moves both right and up, the x and y coordinates will change
Answer B is the same as answer A. The kite moved so the coordinates will change.
Answer D is also the same. If the kite moves both on the x and y axis, any angle and distance will change.
Answer C is correct. Since C does not rely on the coordinates, it will always be the same. The position of a shape does not change it´s perimeter.

A rectangle has sides that are 10 m, 10m, 5m, and 5 m. What is the rectangle’s length?
5m
20 m
10 m
30 m
Answers
The way the question is worded is a little confusing.
I think I would say 10m. It could be 5m, but usually they list length first, then width. The perimeter, the whole distance around the outside, is 30 m (10 + 10 + 5 +5)
The length of the rectangle will be 10 m.
What is a rectangle?A rectangle is a two-dimensional shape (2D shape) in which the opposite sides are parallel and equal to each other and all four angles are right angles.
Given that, a rectangle has sides that are 10 m, 10 m, 5 m, and 5 m.
We need to find the length of the rectangle,
We have the dimensions 5 m x 10 m,
Lengths in a rectangle tells that how much the rectangle is long and the width tells how much the width tells about the breadth of the rectangle,
So, we can say that,
Length = 10 m
Width = 5 m
Hence, the length of the rectangle is 10 m.

Answers
The type of graph that allows you to compare the frequency of intervals, but not the frequency of exact values is a stem-and-leaf plot.
What is a Histogram?An histogram is a graphical representation of a data distribution, which uses bars or bins to represent the frequency of the data distribution that are in intervals.
Similarly, in dot plot the total number of dots tells us the total number of observations of the values of that thing we did.
The Stem and leaf plot is to show the data distribution while retaining its uniqueness which shows the raw values by retaining the original data,
The type of graph that allows you to compare the frequency of intervals, but not the frequency of exact values is a stem-and-leaf plot.
Therefore, the graph used to show data in intervals is: B.a stem-and-leaf plot

This graph is a function because it passes the vertical line test. The vertical line test ensures that no x value has more than one y value. You can take a pencil, hold it vertically, and move it horizontally across your paper to test whether or not the graph contains multiple y values for a single x value. If it passes this test, then the graph is indeed a function.
