Omar’s tank is 3/10 full. After he buys 11 gallons of gas, it is 4/5 full. How many gallons can Omar’s tank hold?
Answers
Answer:
22 gallons.
Step-by-step explanation:
11 gallons took you from 3/10 to 4/5 (same as 8/10).
so the 11 gallons was 5/10- or 1/2 the tank.
if 11 gallons =half a tank, then a full tank is 22 gallons

schoology.com/assignment/4674363703/assessment Question 5 (4 points) (08.01) Consider the following pair of equations: x + y = -2 y = 2x + 10 If the two equations are graphed, at what point do the lines representing the two equations intersect? (4 points) a (-4, 2) b (4, 2) (-2, 4)
Answers
Answer:
[tex](x,y) = (-4,2)[/tex]
Step-by-step explanation:
Given
[tex]x + y = -2[/tex]
[tex]y = 2x + 10[/tex]
Required
Determine the point of intersection of both equations (if graphed)
To do this, we solve for x and y
Substitute 2x + 10 for y in the first equation
[tex]x + 2x + 10 = -2[/tex]
[tex]x + 2x = -2 - 10[/tex]
[tex]3x = -12[/tex]
[tex]x = -4[/tex]
Substitute [tex]x = -4[/tex] in the second equation
[tex]y=2x +10[/tex]
[tex]y=2*-4 +10[/tex]
[tex]y=-8 +10[/tex]
[tex]y = 2[/tex]
So, the point of intersection is:
[tex](x,y) = (-4,2)[/tex]

A manufacturer orders lots of steel rods from a supplier (each lot consists of thousands of rods). Assume that the mean length of the rods in each lot is 4 meters and standard deviation is 0.04 meter. The quality manager accepts a lot if the mean length of the randomly selected sample of 64 rods from that lot is at least 4.005 meters, otherwise the lot is returned to the supplier. a) What percentage of the lots received by the manufacturer will be returned to the supplier
Answers
Answer:
84.13% of the lots received by the manufacturer will be returned to the supplier
Step-by-step explanation:
To solve this question, we need to understand the normal probability distribution and the central limit theorem.
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
Assume that the mean length of the rods in each lot is 4 meters and standard deviation is 0.04 meter.
This means that [tex]\mu = 4, \sigma = 0.04[/tex]
Sample of 64:
This means that [tex]n = 64, s = \frac{0.04}{\sqrt{64}} = 0.005[/tex]
a) What percentage of the lots received by the manufacturer will be returned to the supplier
The proportion is the pvalue of Z when X = 4.005. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{4.005 - 4}{0.005}[/tex]
[tex]Z = 1[/tex]
[tex]Z = 1[/tex] has a pvalue of 0.8413
0.8413*100% = 84.13%
84.13% of the lots received by the manufacturer will be returned to the supplier

Answers
Answer:
y = 2x - 3
Step-by-step explanation:
Slope is identified by rise over run so y over x
Looking at the graph, the line rises 2 points and moves 1 point over between each point.
to find the y intercept, look at where the line crosses the y axis, which is at
(0, -3)
thus, fill in the formula
y = mx + b
y = 2x - 3
The price of an amusement park ticket is no less than $19.
The inequality is?
Answers
Answer:
x≥ 19
Step-by-step explanation:
Let the price of an amusement park ticket is x
If the price of an amusement park ticket is no less than x, therefore, it has to be x or greater than x;
The inequality sign to be used will be the greater than or equal to sign (≥). Hence the required inequality is x≥ 19 where x is the price of an amusement park ticket.

Answer:
hope this helps !
your answer should be FG-220.2 feet
Step-by-step explanation:
The base of the triangle is FH
The perpendicular of the triangle GH=57 feet
The hypotenuse of the triangle is FG
We know that
sin∠F=Perpendicular/Hypotenuse
Hypotenuse= Perpendicular/sin∠F
Hypotenuse= 57/sin∠15
Hypotenuse=220.23109
Round of to nearest tenth
