Answer:
Step-by-step explanation:
Subtracting a number is the same as adding its opposite. So, subtracting a positive number is like adding a negative; you move to the left on the number line. Subtracting a negative number is like adding a positive; you move to the right on the number line.

Answer:
d =13 cm
r = 6.5 cm
Step-by-step explanation:
The diameter is the distance across the circle, going through the center
d = 13 cm
The radius is 1/2 of the diameter
r = d/2 = 13/2 = 6.5 cm
Answer:
Radius is 6.5
Diameter is 13
Step-by-step explanation:
The diameter is the distance across the circle. The radius is half the distance across the circle.
A circle with circumference 6 has an arc with a

E) Calculate the residuals for your scatterplot in step 2d (image attached below)
F) create a residual plot for your data
I’LL VOTE 5 STARS TOO!
Answer:
In the simplest meaning, you have:
Residual (e) = Observed value (y) - Predicted value (y')
Here, observed value y has been provided in table.
The predict value y' is calculated based on the linear regression model shown in your picture: y = 0.161x + 0.748, by substitute x into this model, you obtain the predict value y'.
x = 1.11, 18, 21.9, 18, 16.7, 20, 15.5, 19.5
=> Corresponding y' would be:
y' = 0.93, 3.65, 4.27, 3.65, 3.44, 3.97, 3.24, 3.89
From the table, you have corresponding observed value y:
y = 0.7, 4, 3.69, 3.8, 3.21, 4, 3.92, 3.77
=> Subtract y to y', you obtain the corresponding residual e:
e = -0.23, 0.35, -0.58, 0.15, -0.23, 0.03, -0.68, -0.12
Plot vector e on y axis, and vector x on x-axis respectively, you got the residual plot
Hope this helps!

Answer:
E) -0.23, 0.35, -0.58, 0.15, -0.23, 0.03, -0.68, -0.12
F) on the horizontal axis, take the x values and on the vertical axis, take residuals
Step-by-step explanation:
Given:
y = 0.7, 4, 3.69, 3.8, 3.21, 4, 3.92, 3.77
Using the regression equation:
y' = 0.93, 3.65, 4.27, 3.65, 3.44, 3.97, 3.24, 3.89
Residuals: y - y'
-0.23, 0.35, -0.58, 0.15, -0.23, 0.03, -0.68, -0.12
What is the sample space for a 5 sided number cube?
Answer:
{1, 2, 3, 4, 5}
Step-by-step explanation:
Sample space is the set of all possible outcomes. Supposing that the 5 sided number cube has numbers one to five on its sides, the possible outcomes are the numbers that can be rolled, then its sample space is: {1, 2, 3, 4, 5}

Answer:
11.3
Step-by-step explanation:

Answer:
11.3
Step-by-step explanation:
In a right angled triangle: the square of the hypotenuse is equal to
the sum of the squares of the other two sides.
[tex]8^{2} + 8^{2} = x^{2}[/tex] (x is the hypotenuse)
64 + 64 = [tex]x^{2}[/tex]
[tex]x^{2}[/tex] = 128

population. Which was most likely true of the representative sample?

The representative sample contained all 160 students,
The representative sample contained more boys than girls.
The representative sample contained more girls than boys.
The representative sample contained an equal number of boys and girls,
Save and Exit
Next
Submit
Mark this and retum
Answer:
The representative sample contained more girls than boys.
Step-by-step explanation:
A "sample" of something is a small part of it. A "representative sample" is a small part of the students that represents them all. A random sample would not include all 160 students. It is more likely that there would be more girls than boys, than more boys than girls. In total, there are more girls than boys: 95 girls to 65 boys. It is more likely that a sample of the total students would be just like the total, but smaller.

What type of function is represented in the table? x|0|1|2|3|4|5|
A exponential B logarithmic C linear D quadratic. y|-1|0|-3|-10|-21|-36|
Answer:
This may be wrong but im guessing it is B.logarithmic
Step-by-step explanation:
The type of function is Quadratic.
What is function?An expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given that;
x 0 1 2 3 4 5
y - 1 0 - 3 - 10 - 21 - 36
As, we can see from the table ,
The first differences of the y-values are 1, 0, -3, -7, -11, -15, which are not constant.
However, the second differences are all equal to -4, which indicates that the function has a quadratic form.
Hence, the function is quadratic.

The average age of people attending a concert was 23 years old, with a standard deviation of 7. What percentage of people at the concert were older than 37 years old?
Answer:
2.28%
Step-by-step explanation:
We have that the mean (m) equals 23 and that the standard deviation (sd) is 7.
We can calculate the value z and in this way we can calculate the probability in this case with the calculation of the normal distribution table:
z = m - x / sd
we know that x is 37, replacing:
z = (23 - 37) / 7
z = -2
according to the normal distribution table the value of z = -2, is equivalent to 0.0228
So the probability is 2.28%
Segments AB, DC and Ec intersect at point C. Angel DCE measures 148. Find the value of x.
The image is attached.
Answer:
x = 16°
Step-by-step explanation:
Segment AB, segment DC and segment EC all intersect at point C.
Here, we are told angle DCE measures 148°.
This is a semi-circle, and the total angle of a semi-circle is 180°.
Which means, x+x+148 = 180
Solving for x, we have:
x+x+148 = 180
2x + 148 = 180
2x = 180 - 148
2x = 32
[tex]x = \frac{32}{2}[/tex]
x = 16°
The value of x is 16°

10. Two sides of a triangle have
the following measures. Find the
range of possible measures for
the third side.
35, 29
7
6
8
9
Answer:
The range of possible measures for the third side are 6 < x < 64.
Step-by-step explanation:
The sum of two sides of a triangle is always greater than the third side.
The two sides of a triangle are:
A = 35
B = 29
Suppose the third side is, C = x.
Then,
A + B > C
⇒ 35 + 29 > x
⇒ 64 > x
⇒ x < 64
But for the inequality theorem to be consistent for all the three sides, the third side must have a lower bound.
The difference between the two provided side is,
Diff = 35 - 29 = 6
The third side should not be less than 6 for the inequality theorem to hold.
Thus, the range of possible measures for the third side are 6 < x < 64.
Which trigonometric ratio for a˚ belongs with each value. Enter sin, cos, or tan in each box.
A right angle triangle with one angle a degree. The adjacent sides 6 and opposite side is 9. The hypotenuse 3 square root of 13.
= 313√13
= 213√13
= 32
Hey there! I'm happy to help you!
When talking about trigonometric ratios, we can use a handy little mnemonic device called soh cah toa which shows us the ratios for each one. Soh is sine equals opposite over hypotenuse, cah is cosine equals adjacent over hypotenuse, and toa is tangent equals opposite over adjacent.
In our triangle, we can apply the following with the given information.
[tex]sin=\frac{opposite}{hypotenuse} =\frac{9}{3\sqrt{13} } =\frac{3}{\sqrt{13} } =\frac{3\sqrt{13} }{13} \\\\cos=\frac{adjacent}{hypotenuse} =\frac{6}{3\sqrt{13} } =\frac{2}{\sqrt{13} } =\frac{2\sqrt{13} }{13} \\\\tan=\frac{opposite}{adjacent} =\frac{6}{9} =\frac{2}{3}[/tex]
Therefore, the answers will be sin, cos, and then tan going down in the answer order you gave!
