EVELYN HAD 9 DOLLS, BUT SHE LOST 1/3RD OF THEM AT DAYCARE. HOW MANY TOTAL DOLLS WOULD EVELYN HAVE HAD IF SHE HAD NOT LOST THEM?
Answer:
Total Dolls would Evelyn have had if she had not lost them = 9 Dolls
Step-by-step explanation:
As given,
Total dolls Evelyn had = 9
Total dolls lost = [tex]\frac{1}{3}[/tex]× 9 = 3
So, Now
Evelyn had total dools after lost = 9 - 3 = 6
If she had not lost te dolls , then she had 3 dolls more
∴ we get
If she had not lost any dolls , Evelyn had total dolls = 6 + 3 = 9
So, The answer would be :
Total Dolls would Evelyn have had if she had not lost them = 9 Dolls
Describe and correct the error in graphing the system of inequalities.
Answer: The boundary lines are correct, but there shouldn't be any shaded region
==========================================================
Explanation:
The graph of [tex]y \le x-1[/tex] will have us graph the boundary line y = x-1, and then shade below this solid boundary line. The boundary line y = x-1 is shown as the bottom boundary line of that diagram.
The graph of [tex]y \ge x+3[/tex] involves the boundary line y = x+3, with shading above the boundary line. The graph of y = x+3 is shown as the top boundary line of that diagram.
The boundary lines are correctly graphed, but the shaded region is incorrect. Instead, there shouldn't be any shaded region. The two shaded regions mentioned in the previous paragraphs do not overlap at all, so we don't have any (x,y) point that is in both shaded regions simultaneously. Therefore, there are no solutions to this entire system.
-----------------------------
Here's another reason why there's no solution region.
For each given inequality, subtract x from both sides
So [tex]y \le x-1[/tex] turns into [tex]y-x \le -1[/tex], while [tex]y \ge x+3[/tex] turns into [tex]y-x \ge 3[/tex]
Next, let z = y-x
We can replace each copy of 'y-x' with 'z' and we end up with the two inequalities [tex]z \le -1[/tex] and [tex]z \ge 3[/tex]
However, no such number is both -1 or smaller, AND 3 or larger
So there is no solution to that system involving z. Consequently, there are no solutions to the original system of inequalities.

Over what interval is the function in this graph constant? A. 65*10 B, 1 sxs6 C. -4 sxs1 D. -10 5-4
Given:
The graph of a function.
To find:
The interval at which the graph of the function is a constant.
Solution:
From the given graph it is clear that the graph is a horizontal line and parallel to the x-axis over the interval [tex]1\leq x\leq 6[/tex].
Over the interval [tex]1\leq x\leq 6[/tex], the value of the function is constant, i.e., y=7.
It means the graph of the function is constant over the interval [1,6].
Therefore, the correct option is B.

What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the number be A = 42
Now , let the percentage of the number A = 23 %
And , the equation will be
The 23 % of the number be = y
So , y = 23 % of 42
And , the equation is
y = ( 23 / 100 ) x 42
y = 0.23 x 42
On simplifying the equation , we get
y = 9.66
y ≈ 9.7
Therefore, the value of y is 9.7
Hence , The value of 23 % of 42 is 9.7

Step-by-step explanation:
I apologize if any of my answers are wrong.
For #1, WT is the same at WU, so the answer should be 7 inches
For #2, it looks like QT is just WT+QW. 7+16 is 23. Answer is 23 inches
For #3, PW is the same as QW so we can automatically assume the answer is 16 inches.
For #4, PU is the same at QT, so 23 inches
For #5, I'm pretty sure the distance between TR is the same as PT, so 8 inches for #5
For #6, PR*2 or 8*2 is 16, so 16 inches

Step-by-step explanation:
Multiply the dividend fraction numerator with the divisor fraction denominator to get the numerator
Multiply the dividend fraction denominator with the divisor fraction numerator to get the denominator = 36/12
Reduce the fraction by finding the greatest common factor. The greatest common factor of 36 and 12 is 12
Divide the numerator and denominator by the greatest common factor (12)
= 3/1
Convert to a mixed fraction by finding the whole number and remainder

Answer:
Step-by-step explanation:
∠L = 52
∠N = 26
8) ∠M + ∠N = 180 {in trapezoid, LM // PN, co interior angles}
∠M + 26 = 180
∠M = 180 - 26
∠M = 154
11) ∠LPN + ∠L = 180 {in trapezoid, LM // PN, co interior angles}
∠LPN + 52 = 180
∠LPN = 180 - 52
∠LPN = 128
9)In ΔPAN,
∠PAN + ∠N + ∠NPA = 180 {Angle sum property}
90 + 26 + ∠NPA = 180
116 + ∠NPA = 180
∠NPA = 180 - 116
∠NPA = 64
∠LPA + ∠NPA = ∠LPN
∠LPA + 64 = 128
∠LPA = 128 - 64
∠LPA = 64
10) ∠MAP = 90 {PA ⊥ MN}

5(y+2/5)=-13
what is y
Answer:
y=11/5
Step-by-step explanation:
first divide by 5 on both sides
y+2/5=-13/5
subtract 2/5 on both sides to isolate the y
y=11/5
:))
Answer:
y=-3
Step-by-step explanation:
5(y+2/5) = -13
5y+2 = -13
subtract 2 from each side
5y+2-2 = -13-2
5y = -15
divide each side by 5
5y/5 = -15/5
y=-3
check:
5(y+2/5) = -13
substitute -3 for y
5(-3)+2/5) = -13
-15+2= -13
-13 = -13

Answer:
x is less than or equal to 0
Step-by-step explanation:
- you need to multiply both sides of the inequality by 5/2
- then you reduce the numbers with the greatest common factor 5
- then you reduce the numbers with the greatest common factor 2
- any expression multiplied by 0 equals 0
- so you get x is less than or equal to 0

Make a conditional relative frequency table for the columns of movie type. Determine which statement has the strongest association.
Do you prefer watching a comedy, a drama, or a thriller movie?
Comedy Drama Thriller Row Totals
Males 40 23 56 119
Females 21 45 18 84
Column Totals 61 68 74 203
Females prefer drama movies.
Males prefer comedy movies.
Males prefer thriller movies.
Females prefer comedy movies.
Answer:
C. Males Prefer thriller movies. I'm pretty sure. I'd need the photo.
Step-by-step explanation:
If you look at the graph you'll see that 56 males like thriller while only 18 of women like it. These two data points have a difference of 38, making it the largest difference than any other category, therefore, its the strongest.
The females who prefer drama movies has the strongest association option (A) Females who prefer drama movies is correct.
What is a conditional relative frequency?It is defined as the frequency that can be evaluated by the two-way frequency table. Usually, we can obtain this frequency by dividing the frequency that is not in the total the equency cell to total frequency.
We have:
A conditional relative frequency is given:
From the data:
Probability of Females preferring drama movies :
= n(Females who prefer drama)/n(females )
= 45/84 = 0.53
Probability of Males preferring comedy movies :
n(males who prefer comedy) / n(males)
= 40/119 = 0.33
The probability of Males prefers thriller movies.
n(males who prefer prefer thriller ) / n(males)
= 56/119 = 0.47
The probability of Females prefers thriller movies.
n(females who prefer prefer thriller ) / n(females)
= 18/84 = 0.21
Thus, the females who prefer drama movies has the strongest association option (A) Females who prefer drama movies is correct.

Answer:
7 (6 as exponent)
Step-by-step explanation:
Given the repeated product of a number to be expressed in exponential terms, we take the number as the base and the number of times it is multiplied as the exponent or power.
As such, given 7 x 7 x 7 x 7 x7 x 7
the base is 7 and since the number of 7s being multiplied is 6, the result is
7 exponent 6 which may be written as 7^6
