Answer:

y = (5/3)x + 4

Step-by-step explanation:

-5x + 3y = 12 (What you start with)

3y = 12 + 5x (Adding 5x to both sides)

y = (5/3)x + 4 (Dividing the equation by 3)

Answer:

1/10 or 10%.

Step-by-step explanation:

If the generator includes the numbers 1 and 10 then there are a total number of 10 possible number outcomes that the number generator can generate. Out of all of these outcomes, only one of those would be generating a 7. Therefore, the probability of the generator generating a 7 would be 1/10 or 10%. This is assuming that it only generates 1 number.

Answe - 0. 5692

Step-by-step explanation:

the step is only to let 1 be 10000 and then subtract 4308 from 10000 and it u have any confusion then u can also check it by adding the answer with 4308

and that's it.

If u think it's helpful then plz share to ur friends too.

The difference is 0.5692.

Decimal numbers are numbers which has basically a whole number part and a fractional or decimal part after a point called decimal point.

Decimal number system describes the base 10 number system.

Here we have to find the difference of 1 - 0.4308.

Here, the number is 0.4308, which is a decimal number.

Write 1 as the decimal number as 1.0000

Subtracting as done as usual whole numbers, we get,

1.0000 - 0.4308 = 0.5692

Hence the difference of the given numbers is 0.5692.

The equation of the line passing from the given points is y = -5x/2-1

An equation is a mathematical statement that shows that two mathematical expressions are equal.

Given that, a line is passing through two points (-2, 4) and (0 -1)

We know that, the equation of a line passing through two points is given by,

y-y₁ = (y₂-y₁/x₂-x₁)(x-x₁)

Therefore,

y-4 = (-1-4)/(0+2)(x+2)

y-4 = -5/2(x+2)

y = -5x/2-5+4

y = -5x/2-1

Hence, The equation of the line passing from the given points is y = -5x/2-1

Answer:

95.5°F

Step-by-step explanation:

Given the regression equation :

y = 1.8x - 76.9 ; the relationship between temperature (°F) and number of ice cream sold

y = number of ice cream sold

x = temperature (°F)

The temperature when 95 iccream cones are sold will be ;

Here, y = 95

Using the model :

95 = 1.8x - 76.9

95 + 76.9 = 1.8x

171.9 = 1.8x

Divide both sides by 1.8

171.9 / 1.8 = x

95.5°F = x

Hence, temperature when 95 cones of ice-cream are sold is 95.5°F

Answer:

[tex]t _{critical} = 1.760[/tex]

t = 2.2450

d. 0.264

Step-by-step explanation:

The null hypothesis is:

[tex]H_o: \mu_1 - \mu_2 = 0[/tex]

Alternative hypothesis;

[tex]H_a : \mu_1 - \mu_2 > 0\\[/tex]

The pooled variance t-Test would have been determined if the population variance are the same.

[tex]S_p^2 = \dfrac{(n_1-1)S_1^2+(n_2-1)S^2_2}{(n_1-1)+(n_2-1)}[/tex]

[tex]S_p^2 = \dfrac{(8-1)2.507^2+(8-1)2.8282^2}{(8-1)+(8-1)}[/tex]

[tex]S_p^2 = 7.14[/tex]

The t-test statistics can be computed as:

[tex]t= \dfrac{(x_1-x_2)-(\mu_1 - \mu_2)}{\sqrt{Sp^2 ( \dfrac{1}{n} +\dfrac{1}{n_2})}}[/tex]

[tex]t= \dfrac{(9-6)-0}{\sqrt{7.14 ( \dfrac{1}{8} +\dfrac{1}{8})}}[/tex]

[tex]t= \dfrac{3}{1.336}[/tex]

t = 2.2450

Degree of freedom [tex]df = (n_1 -1) + ( n_2 +1 )[/tex]

df = (8-1)+(8-1)

df = 7 + 7

df = 14

At df = 14 and ∝ = 0.05;

[tex]t _{critical} = 1.760[/tex]

Decision Rule: To reject the null hypothesis if the t-test is greater than the critical value.

Conclusion: We reject [tex]H_o[/tex] and there is sufficient evidence to conclude that the test scores for contact address s less than Noncontact athletes.

To calculate r²

The percentage of the variance is;

[tex]r^2 = \dfrac{t^2}{t^2 + df}[/tex]

[tex]r^2 = \dfrac{2.2450^2}{2.2450^2 + 14}[/tex]

[tex]r^2 = \dfrac{5.040025}{5.040025+ 14}[/tex]

[tex]r^2 = 0.2647[/tex]

Answer:

[tex]y = 5x - 3[/tex]

Step-by-step explanation:

Given

[tex]Slope, m = 5[/tex]

[tex](x_1,y_1) = (2,7)[/tex]

Required

Determine the line equation

Using slope intercept form, the line equation can be calculated using:

[tex]y - y_1 = m(x - x_1)[/tex]

Substitute values for m, x1 and y1. The equation becomes

[tex]y - 7=5(x - 2)[/tex]

Open Bracket

[tex]y-7 = 5x - 10[/tex]

Add 7 to both sides

[tex]y-7+7 = 5x - 10+7[/tex]

[tex]y = 5x - 3[/tex]

Hence, the line equation is: [tex]y = 5x - 3[/tex]

Answer:

[tex]x=21[/tex]

Step-by-step explanation:

See attachment for triangle

The relationship between length x, length 24 and angle 30 is as follows:

[tex]\cos(\theta) = \frac{Adjacent}{Hypotenuse}[/tex]

In this question;

[tex]Adjacent = x[/tex]

[tex]Hypotenuse= 24[/tex]

[tex]\theta = 30[/tex]

Substitute these values in the above expression,

[tex]\cos(30) = \frac{x}{24}[/tex]

Multiply through by 24

[tex]24 * \cos(30) = \frac{x}{24} * 24[/tex]

[tex]24 * \cos(30) = x[/tex]

Reorder:

[tex]x = 24 * \cos(30)[/tex]

[tex]x = 24 * 0.8660[/tex]

[tex]x = 20.784[/tex]

Answer: C. n//p

Step-by-step explanation:

Given:

One airplane is at 7,000 feet and is descending 50 feet every second.

Another plane is at  1,000 feet and is climbing at a rate of 70 feet per second.

To find:

The time taken by planes to reach at the same height.

Solution:

Let x be the number of seconds after which the planes be at the same height.

One airplane is at 7,000 feet and is descending 50 feet every second.

Change in 1 second = -50 feet   (Here negative sign means decrease)

Change in x second = -50x feet

Height of first airplane after x seconds is

[tex]f(x)=7000-50x[/tex]           ...(i)

Another plane is at  1,000 feet and is climbing at a rate of 70 feet per second.

Change in 1 second = 70 feet

Change in x second = 70x feet

Height of first airplane after x seconds is

[tex]g(x)=1000+70x[/tex]     ...(ii)

Equate (i) and (ii), to find the time after which both planes are on the same height.

[tex]7000-50x=1000+70x[/tex]

[tex]7000-1000=50x+70x[/tex]

[tex]6000=120x[/tex]

Divide both sides by 120.

[tex]50=x[/tex]

Therefore, both planes are at the same height after 50 seconds.

Step-by-step explanation:

the common one is 2

Answer:

2/3 plus 3/4 is 17/12.

Step-by-step explanation:

this is because the common denominator is 12, and once you add it all you get 17/12 :))

The factors of the expression 42 - 12 are 2(21 - 6), 3(14 - 4), 6(7 - 2).

The GCF of two or more than two numbers is the highest number that divides the given two numbers completely.

We also know that distributive property states a(b + c) = ab + ac.

Given, We have to factor 42 - 12.

Now, Factors of 12 are 1, 2, 3, 4, 6 and 12.

Factors of 42 are 1, 2, 3, 6, 7, 14, 21 and 42.

Common factors of 12 and 42 are 2, 3 and 6.

So, 42 - 12.

= 2(21 - 6).

= 3(14 - 4).

= 6(7 - 2).

The factored form of the expression 42 - 12 using the GCF is 6(7 - 2).

To factor the expression 42 - 12 using the greatest common factor (GCF), we need to find the largest number that divides both 42 and 12.

First, let's find the prime factorization of both numbers:

42 = 2 x 3 x 7

12 = 2 x 2 x 3

Now, let's find the common factors:

The common factors are 2 and 3.

Next, let's determine the GCF by multiplying the common factors:

GCF = 2 x 3 = 6

Finally, we can factor out the GCF from the expression:

42 - 12 = 6 x (7 - 2)

Therefore, the factored form of the expression 42 - 12 using the GCF is 6(7 - 2).

3 apples: 8 people

4 apples: 6 people

6 apples: 4 people

8 apples: 3 people

12 apples: 2 people

24 apples: 1 person

Step-by-step explanation:

The number of 6 people can have 4 apples each.

The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into the same number of parts.

Given:

Priya is sharing 24 apples equally with some friends.

She uses division to determine how many people can have a share if each person gets a particular number of apples.

For example, 24 ÷ 4 = 6 means that if each person gets 4 apples,

then 6 people can have apples,

= 24 ÷ 6

= 4
