Emily answer'd 7 questions correct and 8 incorrect in the second round what was her score in the second round.
Answers
Answer
A. -30 points
B. 60 points
Step-by-step explanation:
20 points for correct answer and 10 points deducted for wrong answer
Each deduction is -10 while each correct answer gives + 20
4 questions correctly and 11 incorrectly
= 4(20) + 11(-10)
= 80-110 = -30 points
Second round
7 correct, 8 incorrect
= 7(20) - 8(10)

Evaluate 7 to the power of 2 pls help
Answers
Answer:
49
Step-by-step explanation:
Whenever you power something, you are just multiplying that number by itself amount of times you are powering
7 to the power of 2 is 7² = 49
The power (or exponent) of a number define how many times to use the number in a multiplication.
It is written as like a small number to the right and above the base number.
In this example the little "2" says to use 8 two times in a multiplication: 82 = 8 × 8 = 64.
To evaluate 7 to the power of 2.
7² = 7 × 7 = 49
Therefore, 7 to the power of 2 is 49.

Fifteen billiard balls are numbered 1 to 15. One billiard ball is selected at random. Determine the odds for and the odds against for (6 Points) a) selecting the number 7 b) selecting a number greater than 10
Answers
Answer:
Odds for & against selecting number 7 = 1/14 & 14
Odds for & against selecting number more than 10 = 4/11 & 11/4
Step-by-step explanation:
Odds for event = Prob (event) / Prob (no event)
Odds against event = Prob (no event) / Prob (event)
Odds for selecting number 7Prob (No. 7 chosen) = 1/15 , Prob (No. 7 not chosen) = 14/15
Odds for number 7 = (1/15) ÷ (14/15) = 1/14
Odds against number 7 = (14 / 15) ÷ (1/15) = 14
Odds for selecting number > 10Prob (No. > 10 chosen) = 4 / 15 , Prob (No. > 10 not chosen) = 11/15
Odds for No. > 10 = (4/15) ÷ (11/15) = 4/11
Odds against No. > 10 = (11/15) ÷ (4/15) = 11/4

Answers
Answer:
m=4
Step-by-step explanation:
−9(m+3)+14=−49
Step 1: Simplify both sides of the equation.
−9(m+3)+14=−49
(−9)(m)+(−9)(3)+14=−49(Distribute)
−9m+−27+14=−49
(−9m)+(−27+14)=−49(Combine Like Terms)
−9m+−13=−49
−9m−13=−49
Step 2: Add 13 to both sides.
−9m−13+13=−49+13
−9m=−36
Step 3: Divide both sides by -9.

When completing the square is carried out on the quadratic [tex]x^2+11x[/tex] we get

when expressed as a binomial squared, we get

To complete the square, we need to add a term to the expression
[tex]x^2+11x[/tex]
that would make it a perfect square. Generally, given the quadratic expression
[tex]x^2+bx[/tex]
to make it a perfect square, we have to add half the square of the coefficient of [tex]x[/tex]. That is, add [tex]\left(\frac{b}{2}\right)^2[/tex], or [tex]\frac{b^2}{4}[/tex] to the quadratic expression to get

The volume of a fish tank is given by the function V (x) = (x + 7) (1-4) (2x + 3). Write a function describing a fish tank that has the same height but is
longer in length by 3 units and wider by 2 units.
Answers
Answer:
V(x)=(x+9) * (3) * (2x + 6)
Step-by-step explanation:
A fish tank is usually made in the shape of a 3-Dimensional rectangular prism. The volume of this shape can be obtained by using the following formula
V = w * h * l
in this formula w represents the width, h represents the heigh, l represents the length, and V represents the volume of the rectangular prism/fish tank. Therefore, we can use the function provided in the question and simply add 3 units to the length and 2 units to the width in order for it to work for our new fish tank.
V(x)=(x+9) * (3) * (2x + 6)

Answer:
Fraction of saving = 1/8
Step-by-step explanation:
Given:
Spent on bills = 3/8
Spend on food = 2/5
Spend on entertainment = 1/10
Find:
Fraction of saving
Computation:
Fraction of saving = 1 - Spent on bills - Spend on food - Spend on entertainment
Fraction of saving = 1 - 3/8 - 2/5 - 1/10
By taking LCM
Fraction of saving = [40 - 15 - 16 - 4]/40
Fraction of saving = [5]/40
Fraction of saving = 1/8

Marita's nose is 2 inches long and her head is 9 inches tall. Assume Mount Rushmore was carved using the same ratio. If Teddy Roosevelt's head is 60 feet tall, how long should his nose be? Round to the nearest foot, if necessary.
Answers
Answer:
13 1/3
Step-by-step explanation:
So the question is Marita's nose is 2 inches long and her head is 9 inches tall. Assume Mount Rushmore was carved using the same ratio. If Teddy Roosevelt's head is 60 feet tall, how long should his nose be? Round to the nearest foot, if necessary.
First divide 60 by 9 to figure out the first part of the ratio. So that is 60/9 or 6 2/3.
Then multiply 2 by 6 2/3 which is 13 1/3.
Finally when rounded to the nearest foot, it will be 13.

Misty correctly determined the equation of the linear function represented by the table of values below to be y = negative 2 x + 9 in slope-intercept form by using the ordered pairs (1, 7) and (2, 5).
Answers
Answer:
we can verify that the determined equation is the same as the equation determines by Misty, hence, we conclude that Misty had correctly determined the equation of the linear function.
Step-by-step explanation:
As Misty determined the equation of linear function:
[tex]y=-2x+9[/tex]
We need to check whether she has got the correct equation or not.
As the linear equation passes through the points [tex](1, 7)[/tex] and [tex](2, 5)[/tex].
Finding the slope:
The slope between two points [tex](1, 7)[/tex] and [tex](2, 5)[/tex]
[tex]\left(x_1,\:y_1\right)=\left(1,\:7\right),\:\left(x_2,\:y_2\right)=\left(2,\:5\right)[/tex]
[tex]m=\frac{5-7}{2-1}[/tex]
[tex]m=-2[/tex]
As we know the point-slope form is:
[tex]y-y_1=m\left(x-x_1\right)[/tex]
So, the equation of the line will be:
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-5=-2\left(x-2\right)[/tex]
Add 5 to both sides
[tex]y-5+5=-2\left(x-2\right)+5[/tex]
[tex]y=-2x+9[/tex]
From the above calculation, we can verify that the determined equation is the same as the equation determines by Misty, hence, we conclude that Misty had correctly determined the equation of the linear function.
