6. HANG GLIDING Aida
was hang gliding. After losing
35 feet in altitude, she was
gliding at 125 feet. Write and
solve an equation to find her
height when she started hang
gliding.
Answer:
35+125=160
She was 160 feet up when she began hang gliding
Answer:
160
Step-by-step explanation:
let A represent Aida hang gliding
we know that she was at 125 ft in the air
we know that she lost 35 ft in altitude
so the equation would be
125=A[-35]
what is boxed you change the opposite so the opposite of subtraction would be addition.
125=A[-35]
125=A+35
now we move the +35 under 125
if we add 125 and 35 it would give us 160 so the answer would be 160

The points (0,2), (1,3), (2,6), and (3,11) are on the graph of a function. Which of the following equations represents that function?
A.h(x)=x^2+2
B.h(x)=0.5x^2+1.5
C.h(x)=2x^2
D.h(x)=x+2
Given:
The points (0,2), (1,3), (2,6), and (3,11) are on the graph of a function.
To find:
The function.
Solution:
In option A,
[tex]h(x)=x^2+2[/tex]
Putting x=0, 1, 2, 3 respectively, we get
[tex]h(0)=(0)^2+2=2[/tex]
[tex]h(1)=(1)^2+2=3[/tex]
[tex]h(2)=(2)^2+2=6[/tex]
[tex]h(3)=(3)^2+2=11[/tex]
The function passes through the points (0,2), (1,3), (2,6), and (3,11). So, [tex]h(x)=x^2+2[/tex] is the required function.
In option B,
[tex]h(x)=0.5x^2+1.5[/tex]
At x=0,
[tex]h(0)=0.5(0)^2+1.5=1.5\neq 2[/tex]
So, option B is incorrect.
In option C,
[tex]h(x)=2x^2[/tex]
At x=0,
[tex]h(0)=2(0)^2=0\neq 2[/tex]
So, option C is incorrect.
In option D,
[tex]h(x)=x+2[/tex]
At x=2,
[tex]h(2)=(2)+2=4\neq 6[/tex]
So, option D is incorrect.
Therefore, the correct option is A.
An inspector working for a manufacturing company hasa 99% chance of correctly identifying defective items and a 0.5% chance of incorrectly classifyinga good item as defective. The company has evidence that 0.9% of the items its line produce isnonconforming.(a) What is the probability that an item selected for inspection is classified as defective
Answer:
Step-by-step explanation:
From the given information:
Let A be the event where an item is identified as defective;
B₁ to be the event where an item is actually defective
B₂ to be the event that the item is good
So;
P(B₁) = 0.009
P(B₂) = 0.991
Probability that an item is classified as defective when it is actually defective is P(A|B₁) = 0.99
Probability that an item is classified as defective when it is actually good is P(A|B₂) = 0.005
∴
Probability of classifying a product as defective = P(A)
P(A) = P(A|B₁) × P(B₁) + P(A|B₂) × P(B₂)
P(A) = 0.99 × 0.009 + 0.005 × 0.991
P(A) = 0.0139
P(A) = 1.39%
the quotient of 12 and the product of 4 and 5 as a numerical expression.
Answer:
Step-by-step explanation:
The "product of 4 and 5" is (4)(5). 12
The quotient of 12 and the product of 4 and 5 is ------------
(4)(5)
The numerical expression for the given phrase is 12/(4×5).
What is a quotient?In arithmetic, a quotient is a quantity produced by the division of two numbers. The quotient has widespread use throughout mathematics, and is commonly referred to as the integer part of a division, or as a fraction or a ratio.
The given phrase is the quotient of 12 and the product of 4 and 5.
Now, 12/(4×5)
= 12/20
= 3/5
= 0.6
Therefore, the numerical expression is 12/(4×5).

A card is drawn from a standard deck and replaced. After the deck is shuffled, another card is pulled. What is the probability that the first card drawn is a diamond and the second card is a club?
Answer:
0.0625 = 6.25% probability that the first card drawn is a diamond and the second card is a club
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
Probability of independent events:
The probability of independent events happening at the same time is the multiplication of the probabilities of each events.
First card:
A standard deck has 52 cards, of which 13 are diamonds. So
[tex]P(A) = \frac{13}{52} = \frac{1}{4}[/tex]
Second card:
The first card is replaced, so still 52 cards, of which 13 are clubs. So
[tex]P(B) = \frac{13}{52} = \frac{1}{4}[/tex]
What is the probability that the first card drawn is a diamond and the second card is a club?
Each drawing is independent, so
[tex]P(A \cap B) = P(A)*P(B) = \frac{1}{4}*\frac{1}{4} = \frac{1}{16} = 0.0625[/tex]
0.0625 = 6.25% probability that the first card drawn is a diamond and the second card is a club
Answer:
0.0625 = 6.25% probability that the first card drawn is a diamond and the second card is a club

P-21=34 P=34-21 P=13
What is the value of p?
Simplifying
P + -21 + -21 = 34 + -21
-21 + -21 + P = 34 + -21
Combine like terms: -21 + -21 = -42
-42 + P = 34 + -21
Combine like terms: 34 + -21 = 13
-42 + P = 13
Solving
-42 + P = 13
Solving for variable 'P'.
Move all terms containing P to the left, all other terms to the right.
Add '42' to each side of the equation.
-42 + 42 + P = 13 + 42
Combine like terms: -42 + 42 = 0
0 + P = 13 + 42
P = 13 + 42
Combine like terms: 13 + 42 = 55
P = 55
Simplifying
P = 55

One circle has a diameter of 6 inches. A second, larger circle has a diameter that is four times the diameter of the first circle. What is the ratio of the area of the smaller circle to the larger circle?
A 2:3
B 1:6.4
C 1:16
D 1:64
Answer:
Step-by-step explanation:
d₁ = 6 inches
r₁ = 3 inches
area = πr₁² = 9π in²
d₂ = 24 inches
r₂ = 12 inches
area = πr₂² = 144π in²
ratio of areas = (9π)/(144π) = 9/144 = 1/16

Aaron has $36.00 from doing yard work. He gave 1/4 of his $36.00 to his
brother Ryan. How much of his money is still leftover?
Answer:
$27 is left over.
Step-by-step explanation:
If you divide 36 by 4, you can find out what 1/4 of 36 is. 36/4 = 9
This $9 is how much he gave away to his brother. In order to find out how much he has leftover for himself, subtract the $9 from the $36.
36-9 = 27.
Therefore, Aaron has $27 leftover for himself.
