Solve the equation:
3x + 2 = 6x - 7
Answer:
x=3
Step-by-step explanation:
1) Subtract 3x from both sides
2 = 6x - 7 - 3x
2) Simplify 6x - 7 - 3x to 3x - 7
2 = 3x - 7
3) Add 7 to both sides
2 + 7 = 3x
4) Simplify 2 + 7 to 9
9 = 3x
5) Divide both sides by 3
9/3 = x
6) Simplify 9/3 to 3
3 = x
7) Switch sides
x=3
8x − 7y = –5
–x + 4y = –15

A satellite flies 87100 miles in 16.75 hours, How long would it take to fly 104520
miles?
Answer:
22.41
Step-by-step explanation:
Set up a proportion where x is the time to fly 174798 miles
Cross multiply and solve for x:
118404x = 2653433.64
x = 22.41
So, it would take 22.41 hours to fly 174798 miles

The area beneath the normal density curve is separated into three regions by the values
and
. Set the mean of the normal density curve to 6.4, the standard deviation to 0.7, and the -value
of
to 6.7. First, determine the value of the area to the right of .
Place
so that it equally divides the area to the left of
. What is the -value
of ?
The value of the area to the right of X > 6.7 calculated from the normal distribution principle is 0.334
Given the Parameters :
Mean, μ = 6.4Standard deviation, σ = 0.7X = 6.7Using the Zscore formula for a normal distribution :
Zscore = (X - mean) / standard deviationThe Zscore, when X = 6.7
Zscore = (6.7 - 6.4) / 0.7 = 0.4286The area to the right of the distribution :
P(Z > 0.4286) = 1 - P(Z < 0.4286)Using a normal distribution table or calculator :
P(Z > 0.4286) = 1 - 0.66589 = 0.334Therefore, the probability value of P(X < 6.7) is
P(Z > 0.4286) = 0.334Learn more :https://brainly.com/question/8165716
Steven uses a
caliper that has an absolute error of 0.02 millimeters. An object's width is measured
using the caliper, which records a width of 14.5 millimeters. What equation would represent the situation?
A. |x-0.02|=14.5
B. |x-14.5|=0.02
C. |0.02-x|=14.5
D. |14.5-0.02|=x
The relationship between the measured value, error and actual width of the object is |x - 14.5| = 0.02
The measurement error = 0.02 millimeters The measured width of caliper = 14.5 millimetersIf the actual width of the caliper is represented as x
The measurement error is an absolute value which can be calculated thus :|Actual value - measured value| = absolute error |x - 14.5| = 0.02Therefore, the equation which represents the scenario described is |x - 14.5| = 0.02

A tennis player hits a ball hard and 0.4 s later hears the echo sound from a wall. The speed of sound in air is 330 ms. How
?far away is the player from the wall
The distance traveled by the echo is used to determine the player's distance from the wall
The player's distance from the wall is 66 m.
Reason:
Known parameter;
The time after which the tennis player hears the echo of the ball, t = 0.4 s
The speed of sound in air, v = 330 m/s
The distance of the player from the wall = Required
Solution:
Let d, represent the distance of the player from the wall
An echo is the reflection the wave of the sound of hitting the ball that
travels to the wall and back
The distance traveled by the sound to the wall, d, and back, (d again), is 2·d
[tex]Speed = \dfrac{Distance}{Time}[/tex]
Therefore;
[tex]The \ speed \ of \ the \ sound,\ v = \dfrac{2 \cdot d}{t}[/tex]Therefore;
[tex]330 = \dfrac{2 \cdot d}{0.4}[/tex]
330 × 0.4 = 2·d
[tex]d = \dfrac{330 \times 0.4}{2} = 66[/tex]

The function h(x) is a transformation of the square root parent function, f(x)= sqrt x . What function is h(x) ?
Answer:
You can actually change it however you want I just happen to add two underneath the radical which shifted the graph to the left and I subtracted five on the outside of the radical which shifted the graph down five
The function h(x) is a transformation of the square root parent function, f(x)= √x then the function h(x) is√x+2 - 5
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
f(x) = √x
f(x) is a parent function.
a parent function is the core representation of a function type without manipulations such as translation and dilation.
We have to find the function h(x) which is obtained by transforming the function f(x)
From the given graph, the function f(x) is moved up about 2 units and the shifted left of 5 units
h(x) =√x+2 - 5
Hence, the function h(x) is a transformation of the square root parent function, f(x)= √x then the function h(x) is√x+2 - 5

State the null and alternative hypotheses
Hop
H.

Testing the hypothesis, we have that:
The null hypothesis is [tex]H_0: \mu = 5.67[/tex]The alternative hypothesis is: [tex]H_1: \mu \neq 5.67[/tex]The p-value of the test is of 0.002252.The p-value is 0.002252 < 0.01, which means that the final conclusion is that the mean weight of quarts made after 1960 is different than 5.67g.At the null hypothesis, we test if the mean is of 5.670g, that is:
[tex]H_0: \mu = 5.67[/tex]
At the alternative hypothesis, we test if the mean is different of 5.670g, that is:
[tex]H_1: \mu \neq 5.67[/tex]
The test statistic is t = -3.276, with the number of degrees of freedom given by:
[tex]df = n - 1 = 39 - 1 = 38[/tex]
The p-value is found using a t-distribution calculator, using a two-tailed test(as the alternative hypothesis is that the mean is different from the value), with t = -3.276 and 38 df. This p-value is of 0.002252.
The p-value is 0.002252 < 0.01, which means that the final conclusion is that the mean weight of quarts made after 1960 is different than 5.67g.
