What is 1.6 + 4x > 14.
Answers
Answer:
Simplifying
1.6 + 4x = 14
Solving
1.6 + 4x = 14
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-1.6' to each side of the equation.
1.6 + -1.6 + 4x = 14 + -1.6
Combine like terms: 1.6 + -1.6 = 0.0
0.0 + 4x = 14 + -1.6
4x = 14 + -1.6
Combine like terms: 14 + -1.6 = 12.4
4x = 12.4
Divide each side by '4'.
x = 3.1
Simplifying
x = 3.1

Answers
Answer:
A'(1, -1), B'(-1, 1), C'(-1, -1)
Step-by-step explanation:
Coordinates of the vertices of the given triangle ABC are,
A(-1, 1), B(1, -1), C(-3, -1)
We have to find the new coordinates of these vertices after reflection across y = x,
Rule for the reflection of a point across a line, (y = x) is,
(x, y) → (y, x)
Following the given rule of transformation,
A(-1, 1) → A'(1, -1)
B(1, -1) → B'(-1, 1)
C(-3, -1) → C'(-1, -3)

If adult females are randomly selected, find the probability that they have pulse rates with a mean between 70beats per minute and 82beats per minute.
Answers
This question is incomplete.
Complete Question
Assume that females have pulse rates that are normally distributed with a mean of u = 76.0 beats per minute and a standard deviation of 12.5 beats per minute. If 1 adult female is randomly selected, find the probability that her pulse rate is between 70 beats per minute and 82 beats per minute. The probability is (Round to four decimal places as needed.)
Answer:
0.3688
Step-by-step explanation:
The formula for calculating a z-score when given a random sample of numbers is is z = (x-μ)/σ/√n
where x is the raw score,
μ is the population mean, and
σ is the population standard deviation.
mean = 76.0 beats per minute and a standard deviation = 12.5 beats per minute.
n = number of random samples = 1
For 70 beats per minute
z = 70 - 76/12.5/√1
z = -0.48
Probability value from Z-Table:
P(x = 70) = 0.31561
For 82 beats per minute.
z = 82 - 76/12.5/√1
z = 0.48
Probability value from Z-Table:
P(x = 82) = 0.68439
The probability that her pulse rate is between 70 beats per minute and 82 beats per minute.
P(x = 82) - P(x = 70)
0.68439 - 0.31561
= 0.36878
≈ 0.3688

A particle travels along the x axis such that it’s position at time t is given by the function x(t)=2t+t. What is the average speed of this particle over the interval 2
Answers
The required average speed of this particle over interval 2 is less than or equal to t which is less than or equal to 10 is 32 meters/second.
Given that,
A particle travels along the x-axis such that its position at time t is given by,
Function; [tex]\rm x(t)=2t^2+t[/tex]
We have to find,
What is the average speed of this particle over interval 2 is less than or equal to t which is less than or equal to 10?
According to the question,
The position of the particle is given by,
[tex]\rm x(t)=2t^2+t[/tex]
The average speed of this particle is determined by differentiating the function with respect to x,
[tex]\rm \dfrac{dx}{dt} = \dfrac{d(2t^2+t)}{dx}\\\\\dfrac{dx}{dt} = 4t + 1 \\\\v(t) = 4t+1[/tex]
Then,
The average speed of the particle over interval 2 is,
[tex]\rm v(t) = 4t+1 \\\\v(2) = 4(2)+1\\\\v(2) = 8+1 \\\\v(2) = 9 \ meter \ per \ second[/tex]
And the average speed of the particle over interval 10 is,
[tex]\rm v(t) = 4t+1 \\\\v(10) = 4(10)+1\\\\v(10) = 40+1 \\\\v(10) = 41 \ meter \ per \ second[/tex]
Therefore,
The average speed of this particle over interval 2 is less than or equal to t which is less than or equal to 10 is,
[tex]\rm v(t) = v(10)-v(2)\\\\v(t) = 41-9\\\\v(t)= 32 \ meter \ per \ second[/tex]
Hence, The required average speed of this particle over interval 2 is less than or equal to t which is less than or equal to 10 is 32 meters/second.

You decide to purchase a bond for $500. It pays 5% simple interest per year and matures in 5 years. How much interest will you earn once the bond matures? Round your answer to the nearest dollar.
Do NOT round until you have calculated your final answer.
Answers
Answer:
$625
Step-by-step explanation:
You start with $500
The interest per year is 5% or 500 x 0.05 = $25
If it matures 5 years and each year has an increase of $25 then
Year 1 - $525
Year 2 - $550
Year 3 - $575
Year 4 - $600
Year 5 - $625
Answer:
Step-by-step explanation:
We express the interest rate r in decimal form, so we have r=5%=5100=0.05. The principal is P=500 and the time in years is t=5. So, the interest is I=Prt=(500)(0.05)(5)=$125. The interest earned is $125.

By finding the median, it would be 12, since 11+13=24/2=12
The first quartile would be 8, because between 4-11, 8 is in the middle
Then the third quartile would be 15, repeating the same process except with 13-28
So basically the answer is the top right choice. With a median of 12, first quartile 8, third quartile 15
find the slope and y- of the table
Answers
Answer:
y = (3/2) x +6
Step-by-step explanation:
The y-intercept is clearly at y = 6 point (0, 6) of the table.
The slope can be calculated using any two pairs, for example (-4,0) and (-2, 3)
slope = (y2 - y1)/(x2 - x1) = (3 - 0) / (-2 + 4 ) = 3/2
Then the equations of the line in slope y-intercept form is:
y = (3/2) x +6
