Answer:
Marsha's shading: 0.80Grace's shading: 2.40Step-by-step explanation:
You are being asked for the decimal equivalents of 0, 4/5, and 2 2/5.
You have correctly noted that the decimal equivalent of 0 is 0, or 0.0.
__
The decimal equivalents you want are apparently in hundredths. To find the fractional part, solve the proportion ...
(your fraction) = x/100 ⇒ x = 100×(your fraction)
So, for the decimal equivalent of 4/5, you have ...
x = 100(4/5) = 80
and the decimal is
80/100 = 0.80 . . . decimal representing Marsha's shading
__
Similarly, the decimal equivalent of 2/5 is ...
x = 100(2/5) = 40
2 2/5 = 2 40/100 = 2.40 . . . decimal equivalent of Grace's shading

Find the measure of angle BCA?
Answer: 33
Step-by-step explanation: When a tangent and radius intersect (as in the diagram) they will always be perpendicular. And using the Triangle Sum Theorem that all angles add up to 180 when get that m<BCA must be 33 degrees.

A realtor collects the data set given in DS 12.2.4 concerning the sizes of a random selection of newly constructed houses in a certain area together with their appraised values for tax purposes.
1. Fit a linear regression model with appraised value as the explanatory variable and size as the dependent variable.
2. What is the estimate of the error variance?
Answer:
12.327X + 452.084
45206.327
Step-by-step explanation:
The linear regression model obtained by fitting the data using technology is :
ŷ = 12.327X + 452.084
Where, 12.327 = slope ; 452.084 = Intercept ; X = appraised value ; y = Area
The estimated error variance which is the degree of variation between the actual and predicted value.
Error variance = ΣSSE /n-2
n = sample size = 15
ΣSSE = 587682.2638
Error variance = 587682.2638/13
Error variance = 45206.327

Pedro compró un minigimnasio para ejercitarse
en casa y mejorar su condición física. En la
compra le hicieron dos descuentos sucesivos del
30% y el 20%. Si ahorró S/ 352, ¿cuánto pagó?
Answer:
Pedro pagó $448
Step-by-step explanation:
Sea P el precio inicial de un objeto.
Si aplicamos un descuento del X%, entonces el nuevo precio del objeto es:
NP = P*(1 - X%/100%)
y lo que estamos ahorrando es:
P - NP
En este caso, primero tenemos un descuento del 30%, entonces:
NP = P*(1 - 30%/100%) = P*(1 - 0.3)
Luego tenemos otro descuento, esta vez del 20%, entonces:
NP' = NP*(1 - 20%/100%) = P*(1 - 0.3)*(1 - 20%/100%) = P*(1 - 0.3)*(1 - 0.2)
Lo que Pedro ahorra es igual a $352
entonces:
P - NP' = $352
P - P*(1 - 0.3)*(1 - 0.2) = $352
P*(1 - (1 - 0.3)*(1 - 0.2)) = $352
P*(1 - 0.56) = $352
P = $352/(1 - 0.56) = $800
Esto significa que el precio original era $800.
Y lo que pedro pago esta dado por la ecuación:
NP' = P*(1 - 0.2)*(1 - 0.3) = $800*(1 - 0.2)*(1 - 0.3) = $448.
Which of the following statements are true? Select all that apply.
22 and 23 form a linear pair
21 and 24 are supplementary angles.
21+ 2+ 3 = 180
23 + 24 = 21+ 22
21 and 24 are vertical angles.
Answer:
The only true statement is:
"∠3 + ∠4 = ∠1 + ∠2"
Step-by-step explanation:
When we have two lines intersect each other, there are 4 angles generated in the intersection.
Two vertical angles are angles whose only "contact point" is the intersection itself. The vertical angles are supplementary only if the two lines are perpendicular.
While a linear pair are two angles that are separated by one of the lines, and linear pairs are always supplementary.
Now let's look at the image and see which statements are true and which ones aren't.
"∠2 and ∠3 form a linear pair"
If we look at the image, we can see that ∠2 and ∠3 are not separated by one of the lines, ∠2 and ∠3 are vertical angles, then this statement is false.
"∠1 and ∠4 are supplementary angles"
Two angles are supplementary if the sum of the measures is equal to 180°, such that, as stated before, a linear pair of angles are supplementary angles.
In the case of ∠1 and ∠4, we can see that these angles are vertical angles, and we also can see that the lines are not perpendicular, then angles ∠1 and ∠4 are not supplementary.
"∠2 and ∠3 = 180°"
This is the same as saying that "∠2 and ∠3 are supplementary"
By the exact same reasoning than in the previous statement, we can find that this one is false.
"∠3 + ∠4 = ∠1 + ∠2"
We know that ∠1 and ∠2 are a linear pair, then ∠1 and ∠2 are supplementary angles, then:
∠1 + ∠2 = 180°
And we know that ∠3 and ∠4 also are a linear pair, and then also are supplementary angles, then we also have:
∠3 + ∠4 = 180°
Then is true that:
∠3 + ∠4 = ∠1 + ∠2
This statement is true.
"∠2 and ∠4 are vertical angles"
We can see that ∠2 and ∠4 are separated by one of the lines, then these angles form a linear pair.
The statement is false.

Ellianna made a scatter plot that showed a positive association and had one outlier. Write a possible scenario for Ellianna's scatter plot
Hint
o
The scatter plot could show test scores based on number of student absences. The outlier could be a student with high test scores who has many
absences,
The scatter plot could show the amount of pay workers at a factory received based on the number of years they have worked at the factory. The
outlier could be someone who is very skilled and has learned her job quickly.
The scatter plot could show the amount of weight that someone gains based on the number of calories that they consume. The outlier could be
someone who eats few calories and does not gain much weight.
The scatter plot could show the amount of weight that a elephant gains based on its age. The outlier could be an adult elephant that weighs more
than a baby elephant.

Find the value of x. Round your answer to the nearest tenth.
Answer:
B. 16.5
Step-by-step explanation:
Here we can use the opposite and the adjacent from the angle with measurement 20, or tan.
tan theta = opposite / adjacent
Substitute values.
tan 20 = 6 / x
Multiply by x.
x * tan 20 = 6
Divide by tan 20.
x = 6 / tan 20
Evaluate tan 20.
x = 6 / 0.36397023
Divide.
x = 16.48486451
Rounded to the nearest tenth, that makes your answer
B, 16.5

Find the slope and y-intercept of the equation.
y + 7 = 4x

&
y-intercept: -7
slope: 4
&
y-intercept: 7
slope: -4
& y-intercept: 7
Answer:
slope: 4
Y-intercept: -7
Step-by-step explanation:
you would have to solve for y so you subtract the 7 on both sides. then it is in slope-intercept form which is y=mx+b where m is slope and b is the y-intercept. the slope would be 4 and the y-intercept would be -7

Which choices are equivalent to the expression below? Check all that apply 4√3
Answer:
answer is E
Step-by-step explanation:
4 x 12 i= 48
square root of 4=2
12= 4x3
square root of 4 again = 2
2x2 =4
so left with 4 square root 3
The equivalent expressions are (a) [tex]4\sqrt 3 = \sqrt{24} \cdot \sqrt{2}[/tex], (d) [tex]4\sqrt 3 = \sqrt{12} \cdot \sqrt{4}[/tex] and (e) [tex]4\sqrt 3 = \sqrt{48}[/tex]
Equivalent expressionsEquivalent expressions are expressions that have equal values
The expression is given as:
[tex]4\sqrt 3[/tex]
Express 4 as the square root of 16
[tex]4\sqrt 3 = \sqrt{16} \times \sqrt 3[/tex]
Combine the roots
[tex]4\sqrt 3 = \sqrt{16\times 3}[/tex]
[tex]4\sqrt 3 = \sqrt{48}[/tex]
Express 48 as the product of 12 and 4
[tex]4\sqrt 3 = \sqrt{12 \cdot 4}[/tex]
Split, into factors
[tex]4\sqrt 3 = \sqrt{12} \cdot \sqrt{4}[/tex]
Express 48 as the product of 24 and 2 in [tex]4\sqrt 3 = \sqrt{48}[/tex]
[tex]4\sqrt 3 = \sqrt{24 \cdot 2}[/tex]
Split
[tex]4\sqrt 3 = \sqrt{24} \cdot \sqrt{2}[/tex]
Hence, the equivalent expressions are (a), (d) and (e)
