-5 less than or equal to x less than or equal to 5

0 less than or equal to x les than or equal to 5

All real numbers

All positive numbers

Answer:

when we have a function:

y = f(x)

Evaluating the function just means replace the independent variable (x) by a given number.

Then, for the first case we have:

y=5x-4

when x = 5

Here we just need to replace x by 5 in the equation for y.

y = 5*(5) - 4

y = 25 - 4 = 21

for the second case:

y= -2/5x+3/8

when x=1/3

We just need to replace x by 1/3 in the equation, we will get:

y = -2/(5*(1/3)) + 3/8

y = - 2*3/5 + 3/8 = - 6/5 + 3/8

Now we need to find a common multiple between 8 and 5, that common multiple is 8*5 = 40

Then we can rewrite:

y = - (6*8)/40 + (3*5)/40 = (-48 + 15)/40 = -33/40

Finally, for the third case:

Equation Given Value Function Solution

y=3x+1

when x=4

We just need to replace x by 4 in the equation, so we will get:

y = 3*4 + 1

y = 12 + 1 = 13

Answer:

[tex]t = 7.359[/tex]

Step-by-step explanation:

Given

[tex]Range = 60[/tex]

[tex]Min = 5[/tex]

[tex]Max = 65[/tex]

[tex]\bar x = 42.31[/tex]

[tex]\sigma^2 =100.00[/tex]

[tex]\sigma = 10.00[/tex]

[tex]\sum = 1227[/tex]

[tex]n=40[/tex]

Required

The t statistic

This is calculated using:

[tex]t = \frac{\bar x - \mu}{\sigma/\sqrt n}[/tex]

Where

[tex]\mu \to[/tex] Population mean

[tex]\mu = \frac{\sum }{n}[/tex]

[tex]\sum = 1227[/tex] and [tex]n=40[/tex]

[tex]\mu = \frac{1227}{40}[/tex]

[tex]\mu = 30.675[/tex]

So, we have:

[tex]t = \frac{\bar x - \mu}{\sigma/\sqrt n}[/tex]

[tex]t = \frac{42.31 - 30.675}{10/\sqrt{40}}[/tex]

[tex]t = \frac{42.31 - 30.675}{10/6.325}[/tex]

[tex]t = \frac{11.635}{1.581}[/tex]

[tex]t = 7.359[/tex]

Answer:

Cost of each hoodies = $25.5

Cost of each t-shirt = $12.75

Step-by-step explanation:

Given:

Cost of 2 t-shirt and 2 hoodies = $76.50

Cost of 5 t-shirt and 3 hoodies = $140.25

Find:

Cost of each t-shirt

Computation:

Assume;

Cost of each t-shirt = t

Cost of each hoodies = h

So,

2t + 2h = 76.50..........eq1

5t + 3h = 140.25..........eq2

Eq 1 x 2.5

5t + 5h = 191.25.............eq3

Eq3 - Eq2

2h = 51

h = 25.5

Cost of each hoodies = $25.5

2t + 2h = 76.50

2t + 2(25.5) = 76.50

t = 12.75

Cost of each t-shirt = $12.75

The slope of side CD in rhombus CDEF is -2/5. Therefore, option B is the correct answer.

A rhombus can be defined as a special parallelogram as it fulfills the requirements of a parallelogram, i.e. a quadrilateral with two pairs of parallel sides. In addition to this, a rhombus has all four sides equal just like a square. That is why it is also known as a tilted square.

Given that, the rhombus is CDEF and the slope of FC is 5/2.

Here, sides FC and CD are perpendicular.

The slope of a line perpendicular to given line is m₁=-1/m₂

Slope of CD is -2/5.

Therefore, option B is the correct answer.

Answer:

13.5579875<x<14.44201244

Step-by-step explanation:

The formula for calculating the confidence interval is expressed as:

CI = x+/- z × s/\sqrt{n}

x us the mean = 14

Z is the 90% CI = 1.645

S is the standard deviation = 1.9

n is the sample size = 50

Substitute.

CI = 14+/-1.645×1.9/7.07106.

CI = 14+/-1.645×0.26870057

CI = (14-0.44201244, 14+0.44201244)

CI = 13.5579875, 14.44201244

Hence the required interval is 13.5579875<x<14.44201244

Answer:

(4,3)

Step-by-step explanation:

Midpoint formula

The midpoint of the line segment is given by M ( 4 , 3 )

The midpoint of a line segment is a point that lies halfway between 2 points. The midpoint is the same distance from each endpoint.

Measure the distance between the two end points, and divide by 2.

Let A ( x₁ , y₁ ) be the first point

Let B ( x₂ , y₂ ) be the second point

The midpoint between A and B is M ( a , b ) where

a = ( x₁ + x₂ )/2

b = ( y₁ + y₂ ) / 2

Given data ,

Let the first point be A ( -2 , 3 )

Let the second point be B ( 10 , 3 )

Now , let the midpoint of A and B be M ( a , b ) where

a = ( x₁ + x₂ )/2

b = ( y₁ + y₂ ) / 2

On simplifying , we get

a = ( 10 - 2 ) / 2

b = ( 3 + 3 ) / 2

On further simplification , we get

a = 4

b = 3

Hence , the midpoint is M ( 4 , 3 )
