Step-by-step explanation:

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]

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

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.

Step-by-step explanation:

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

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

Hypotenuse=220.2 feet

Answer

y=mx+b

equation: y=3/2x-1

Answer:c= a +b

Step-by-step explanation:

Answer:

x=33

Step-by-step explanation:

If you didn't know all of the angles in a triangle add up to equal 180

We are given to angles, 90 (the square indicates that its a right angle which is equal to 90) and 57

So to find the missing anlge we subtract the given angles from 180

180-90=90

90-57=33

therefore x=33

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
