145 + 19t
Step-by-step explanation:
The set of ordered pairs below is a relation. {(0.5,2), (1.5,5), (4.0,12), (6.5,15)} Which relation has the same domain as the given relation?
{(1,5),(2,2),(-3,15),(-8,12)}
{(0.5,1),(1.5,4),(4.0,11),(6.5,14)}
{(2,1,1),(5,2.2),(12,3.3),(15,4.4)}
{(-1,6.5),(-3,1.5),(-6,4.0),(-10,0.5)}
Given:
The set of ordered pairs is
{(0.5,2), (1.5,5), (4.0,12), (6.5,15)}
To find:
Which relation has the same domain as the given relation?
Solution:
We know that, domain is the set of input values or x-values.
For the given set {(0.5,2), (1.5,5), (4.0,12), (6.5,15)}, the domain is
Domain={0.5, 1.5, 4.0, 6.5}
Similarly,
For {(1,5),(2,2),(-3,15),(-8,12)},
Domain = {1, 2, -3,-8}
For {(0.5,1),(1.5,4),(4.0,11),(6.5,14)},
Domain={0.5, 1.5, 4.0, 6.5}
For {(2,1,1),(5,2.2),(12,3.3),(15,4.4)},
Domain = {2, 5, 12, 15}
For {(-1,6.5),(-3,1.5),(-6,4.0),(-10,0.5)},
Domain = {-1, -3, -6, -10}
So, the relation {(0.5,1),(1.5,4),(4.0,11),(6.5,14)} has the same domain as the given relation.
Therefore, the correct option is B.

In ΔPQR, what is the m∠Q? Enter your answer in the box.
m∠Q=
Answer:
105
Step-by-step explanation:
all of the angles added will add up to equal 180 so we setup the equation
180=11x-5+6x+5+x and solve
step 1 combine like terms
180=18x
step 2
divide each side by 18
x=10
then we just plug in 10 to 11x-5
11x10=110-5=105
angle q=105

0. The weight of an object on the Moon is about 16.5% of its weight on Earth. The weight of an astronaut on the Moon is 24.75 pounds. How much does the astronaut weigh on Earth?
Answer: 150 pounds
Step-by-step explanation:
Let the the astronaut weight on Earth be represented by x.
Based on the information given in the question, thus can be formed into an equation as:
16.5% of x = 24.75
16.5% × x = 24.75
16.5/100 × x = 24.75
0.165x = 24.75
x = 24.75/0.165
x = 150 pounds
The astronaut weigh 150 pounds on Earth.

Kathy was packing lunches for her 5 kids. She put the same items in each lunch box. She then decided to add 2 Oreos to each box. All together, she put 30 items in the lunch boxes. Which equation represents this situation?
Answer:
30/5-2 = number of items in each lunch box before adding the 2 Oreos.
Step-by-step explanation:
30/5=6 items in each box
6-2 Oreos=4 item besides the Oreos
30/5-2 = number of items in each lunch box before adding the 2 Oreos.
A set of biology exam scores are normally distributed with a mean of 70 points and a standard deviation of six points X equal the score on a randomly selected exam from the set find P(X< 73)
Answer: .69
Step-by-step explanation:
Answer on khan
We can write the value in the range P(64 < {x} < 76) as 0.68.
What is standard deviation?In statistics, the standard deviation is a measure of the amount of variation or dispersion of a set of values.
Given is that a set of biology exam scores are normally distributed with a mean of 70 points and a standard deviation of six points X equal the score on a randomly selected exam from the set.
It is given that -
μ = 70
σ = 6
For the range of {x}, we can write -
(μ - σ) < {x} < (μ + σ)
64 < {x} < 76
We can write the range of {z} value as -
(64 - 70)/6 < {z} < (64 + 70)/6
- 1 < {z} < + 1
Now -
P(64 < {x} < 76) = P(x < 76) - P(x < 64) = 0.84 - 0.15 = 0.68
Therefore, we can write the value in the range P(64 < {x} < 76) as 0.68.
