Answer:

for more appropriate it would be 0-2.5, and the max is 15

Step-by-step explanation:

The domain of a graph is the possible x-values of the graph, while the range is the possible y-values.

From the attached graph (see attachment), we have the following observations.

Because the volume of a box cannot be negative, the x-values to use must correspond to non-negative y-values.

Hence, the proper domain of Noah's graph should be 0 to 2.5

And the maximum of the graph is at y = 15

Answer:

41

Step-by-step explanation:

step 1. first, you should plug in all the x's.  x² is 49, 2x is 14. The

equation would then be 49-14+6 which is 41

2x would be 2 x 7 because when 2 numbers are touching, they are to be multiplied.

x² would be 7 x 7 because, when you have a number to the power of 2, you multiply it by itself.

and finally you would get, 49-14+6 and according to PEMDAS, the eqaution hsould go left to right leaving us with the answer of 41.

Answer:

5,608

Step-by-step explanation:

The total monthly pay of Karen is given by the equation A = $ 5,608

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the total monthly pay of Karen be = A

Now , the equation will be

Let the annual pay of Karen be B = $ 67.3 K

1 K = 1000

The value of B = 67.3 x 1000

The value of B = $ 67300

So , annual pay of Karen B = $ 67300

Now , the monthly pay of Karen = annual pay of Karen / 12

Substituting the values in the equation , we get

The monthly pay of Karen A = $ 67300 / 12

The monthly pay of Karen A = $ 5,608.33

Rounding to the nearest dollar , we get

The monthly pay of Karen A = $ 5,608

Therefore , the value of A is $ 5,608

Answer:

-3/5

Step-by-step explanation:

To find slope we use the formula, slope = (y2-y1)/(x2-x1)

We let (3,5) be the first point so, x1 = 3 and y1 = 5

We let (8,2) be the second point so, x2 = 8 and y2 = 2

Now we plug it in the formula,

slope =  (2-5)/(8-3) = -3/5

Answer: z = 7 or z=-5

Step-by-step explanation:

First you need to factor the polynomial.

To factor [tex]z^{2}[/tex]  - 2z -35       You will need to find two numbers that their product is -35 and their sum is -2  and the numbers -7 and 5  works out.

Rewrite the polynomial as,

[tex]z^{2}[/tex] - 7z + 5z - 35  = 0   factor the left by grouping

([tex]z^{2}[/tex] -7z) (5z -35)  = 0

z(z -7)  5(z - 7) = 0      Factor out z-7

(z-7)(z+5) = 0        Now apply the zero product by setting each of them equal 0.

z-7= 0      or  z+5=0

 +7  +7             -5  -5

z = 7     or  z= -5

A sample of size 86 will be drawn from a population with mean 90 and standard deviation 24. Use the TI-84 calculator Part 1 of 2

Find the probability that x will be more than 89. Round the answer to at least four decimal places. The probability that will be more than 89 is Part 2 of 2 Find the 60 percentile of x. Round the answer to two decimal places. The 60 percentile is

.

Answer:

part 1) the probability that x will be more than 89 is 0.6517

part 2) the 60 percentile of x is 90.65

Step-by-step explanation:

Given that;

u = 90, α = 24, n = 86

Part 1 says Find the probability that x will be more than 89

p ( x > 89 ) = p (( x - u)/α√n > (89-90)/24/√86 ))

= p ( z > - 0.39 ) = 1 - p (z ≤ - 0.39  )

from z table, 0.39 → 0.3483

= 1 - 0.3483 = 0.6517

∴ the probability that x will be more than 89 is 0.6517

part 2 says  Find the 60 percentile of x

p( Z < z ) = 0.60

now from the z-table, p(Z < 0.25 ) = 0.60

and we that  x = u + z(α/√n)

x = 90 + 0.25( 24 / √ 86

x = 90.64699 ≈ 90.65

∴  the 60 percentile of x is 90.65

Answer: x+y>5 or (x+y)-5

Step-by-step explanation:

There are two potential ways of writing five less than the sum of x and y. You can use an expression or an inequality.

Inequality

By using an inequality, we would use the less than sign because 5 is less than the sum of x and y.

5<x+y

We can also write it where the variables are on the left side, which is usually preferred.

x+y>5

-------------------------------------------------------------------------------------------------------------

Expression

For an expression, we would basically write an equation, but without the equals sign.

(x+y)-5

Since 5 is less than the sum of x and y, we would subtract 5 from x+y. We don't necessarily need to put parentheses around x+y since the order of operations tells us to add or subtract from left to right in order. It is still good to be specific, saying that it is the sum of x and y.

Answer:

Step-by-step explanation:

Given the dataset 147, 154, 156, 161, 162,

Mean is the sum of the dataset divided by the total number of dataset.

a) Mean = [tex]\sum Xi/N[/tex]

[tex]\overline x = \dfrac{147+154+156+161+162}{5}\\ \\\overline x = \dfrac{780}{5}\\ \\\overline x= 156[/tex]

b) The formula for calculating the deviation from the mean for each value is expressed as [tex]Xi - \overline X[/tex] where;

Xi is value of each item

xbar is the mean = 156

Mean deviation of 147 = 147-156 = -9

Mean deviation of 154 = 154-156 = -2

Mean deviation of 156 = 156-156 = 0

Mean deviation of 161 = 161-156 = 5

Mean deviation of 162 = 162-156 = 6

c) Sum of the deviations [tex]\sum Xi - \overline X[/tex] = (-9-2+0+5+6)

[tex]\sum Xi - \overline X[/tex] = -11+11

[tex]\sum Xi - \overline X[/tex] = 0

Hence the sum of deviation from the mean is 0

Answer:

x < 2

Step-by-step explanation:

We are given the inequality:

[tex]6x < 12[/tex]

We want to solve for x. We must isolate x on one side of the inequality.

x is being multiplied by 6. The inverse of multiplication is division. Divide both sides of the inequality by 6.

[tex]6x/6 < 12/6[/tex]

[tex]x< 12/6[/tex]

[tex]x<2[/tex]

For the values of x where x<2, the inequality 6x < 12 is true.

Answer:

1.9 gallons of 80% and 5.7 gallons of 20%

Step-by-step explanation:

x gallons of 80% alcohol solution is mixed with y gallons of 20% alcohol to make 7.6 gallons of 35% alcohol solution.

Based on the given, we get two equations:

Let's substitute y with y = 7.6 - x:

Then we find the value of y:

So the answer is:

Answer:

1.9 gallons of the 80% solution.

5.7 gallons of the 20% solution,

Step-by-step explanation:

Let the volumes of the 80% and 20 % solutions be x  and y gallons.

Then:

x  +  y = 7.6.

Also, using amounts of pure alcohol:

0.8x + 0.2y = 7.6 * 0.35

0.8x + 0.2y = 2.66           Multiplying this equation by -5:

-4x - y = - 13.3                   Adding this to the first equation:

-3x = -5.7

= 1.9 gallons.

y = 7.6 - 1.9

=  5.7  gallons.

Step-by-step explanation:

rise over run

When there is a linear relationship is observed between the variables, we use  linear regression predict the relationship between them.

Also, we predict the values for dependent variable by modelling a linear model that best fits the data by drawing a line Y=a+bX, where X is the explanatory variable and Y is the dependent variable.

In other words: The line of best fit is a line through a scatter plot of data points that best describes the relationship between them.

That's why the  regression line referred to as the line of best fit.

Answer:

probability of lasting longer = 1.7%

Step-by-step explanation:

We are given:

x' = 14 years

μ = 12.3 years

s = 0.8 years

Thus, let's use the formula for the Z-score value which is;

z = (x' - μ)/s

Thus;

z = (14 - 12.3)/0.8

z = 2.125

From the z-distribution table attached, the p-value is ;

P(x' > 2.125) = 1 - 0.983 = 0.017 = 1.7%

Thus,probability of lasting longer = 1.7%

Answer:

0.0228

Step-by-step explanation:

Given that:

mean (μ) = 75, Standard deviation (σ) = 3.5

The z score is a score used in statistics to measure by how many standard deviations the raw score is above or below the mean. If the z score is positive, it means that the raw sore is above the mean and if the z score is negative then the raw score is below the mean. The z score is given by:

[tex]z=\frac{x-\mu}{\sigma}\\ \\For\ a\ sample \ n, the\ z\ score\ is:\\ \\z=\frac{x-\mu}{\frac{\sigma}{\sqrt{n} } }[/tex]

For x > 76 and a sample (n) = 49:

[tex]z=\frac{x-\mu}{\frac{\sigma}{\sqrt{n} } }\\\\z=\frac{76-75}{\frac{3.5}{\sqrt{49} } }=2[/tex]

From the normal distribution table, the probability that the average score of the 49 players exceeded 76 = P(x > 76) = P(z > 2) = 1 - P(z < 2) = 1 - 0.9772 = 0.0228
