Answer:

3 hours

Step-by-step explanation:

The equation will be

10b+25t ≤ 130 (b = hours of babysitting, t = hours of tutoring)

Plug in the 4 hours of tutoring

10b+(25 times 4) ≤ 130

= 10b+100 ≤ 130

10 times 3 = 30, which answers the question

Since 100 + 30 = 130

Therefore, the answer to the minimum amount of hours Robert has to tutor

to make a minimum of $130 is . . .

Answer:

There are 2 dogs

Explaination:

If there are 28 eyes in total,

Dogs- 4 eyes

Chickens- 8 eyes

Fishes - 16 eyes

In total they have 28 eyes

if there are 16 legs,

Dogs- 8 legs

Chickens- 8 legs

Fishes- 0 legs

So,

2 Dogs

4 Chickens

8 Fishes

( the problem even said that there are twice as many fish as chickens)

Answer:

-5/4

Step-by-step explanation:

The slop is rise over run

which means we need to find the rise over run of this equation:

So the question is how many times do you need to go up/down to get to the next plot on the graph? (Reminder up is positive while down is negative)

So, you go down 5 times which means the top of the slope is -5

Now, how many times do we need to run to get the next plot?

You need to run 4 times to the right to get the next point now we have all the things to solve the problem:

Slope=rise/run

Answer: -5/4

Answer:

x = 7deg

Step-by-step explanation:

Step-by-step explanation:

The critical value that corresponds to a 91% confidence level is 1.7

'Critical value is a cut-off value that is used to mark the start of a region where the test statistic, obtained in hypothesis testing, is unlikely to fall in. In hypothesis testing, the critical value is compared with the obtained test statistic to determine whether the null hypothesis has to be rejected or not.'

According to the given problem,

Confidence level = 91%

Now, α = ( 100 - 91 ) %

             = 9%

             = 0.09

Area of each tail = [tex]\frac{0.09}{2}[/tex]

                             = 0.045

Area in the middle = 1 - 0.045

                               = 0.955

Now, if we look up this area on the z-table, the critical value will come as 1.6954, which is nearly equal to 1.7.

Hence, we can conclude, the critical value is 1.7.

Answer:

A. -1

Step-by-sep explanation:

If PQ is perpendicular to RS, therefore, the slope of RS would be the negative reciprocal of PQ.

Slope of PQ:

P(6,-2), Q(-2, 8)

[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{8 -(-2)}{-2 - 6} = \frac{10}{-8} = -\frac{5}{4} [/tex]

Slope of RS:

Slope of RS is the reciprocal of the slope of PQ, since they are perpendicular.

⅘ is the reciprocal of -⁵/4. Therefore, the slope of RS = ⅘.

Use the slope formula to find the value of y in R(-4, 3), S(-9, y).

[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} [/tex]

Plug in the value

[tex] \frac{4}{5} = \frac{y - 3}{-9 -(-4)} [/tex]

[tex] \frac{4}{5} = \frac{y - 3}{-5} [/tex]

Cross multiply

[tex] (4)(-5) = (y - 3)(5) [/tex]

[tex] -20 = 5y - 15 [/tex]

Add 15 to both sides

[tex] -20 + 15 = 5y - 15 + 15 [/tex]

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

Divide both sides by 5

[tex] \frac{-5}{5} = \frac{5y}{5} [/tex]

[tex] -1 = y [/tex]

y = -1

Hopefully this makes sense, but x=+1 and y=-4

Step-by-step explanation:

Lets start with Y. how do you go from 7 to 3? you subtract 4. then, how do you go from 3 to -1? Well... lets subtract till we get to -1. That would be -4. Can you do that for the rest? if so, your answer is -4 for y. for x it just adds a number each time.

A contingency table

Step-by-step explanation:

Hypothesis tests carried out on contingency tables are based on the chi-square, a statistic.

The contingency table is a Frequency tables of two variables presented at the same time. These tables are constructed when we represent all the levels of a variable as rows in a table and represent the other variables as columns, after which we find the joint or cell frequency for every of the cell.

Answer:

El perímetro y el área de un rectángulo cuyos lados miden 6,3 dm y 48 cm es 222 cm y 3024 cm² respectivamente.

Step-by-step explanation:

Para empezar debes tener en cuenta que las medidas tienen que estar en la misma magnitud; por lo tanto en este caso la unidad de medida elegida a utilizar es centímetros. Por lo que el lado que mide 6,3 dm será expresado en cm. Entonces se puede aplicar la siguiente regla de tres simple: si 1 dm equivale a 10 cm, entonces 6,3 dm a cuántos cm equivale?

[tex]cm=\frac{6,3 dm*10 cm}{1 dm}[/tex]

cm=63

Entonces 6,3 dm= 63 cm

El perímetro es la distancia alrededor de una figura, mientras que el área es las unidades cuadradas dentro de una figura.

El Perímetro de un rectángulo es igual a la suma de todos sus cuatro lados.  Un rectángulo siempre tiene dos pares de longitudes iguales. Entonces en este caso se obtiene:

63 cm + 63 cm + 48 cm + 48 cm= 222 cm

El área de un rectángulo es el producto de la longitud de los lados. Entonces en este caso se obtiene:

63 cm* 48 cm= 3024 cm²

El perímetro y el área de un rectángulo cuyos lados miden 6,3 dm y 48 cm es 222 cm y 3024 cm² respectivamente.

Step-by-step explanation:

The line through these points intersects the x-axis at x=3.

The x-intercept is (3, 0).

_____

The x-intercept can be computed from ...

  x-intercept = x1 -y1(x2 -x1)/(y2 -y1)

  = -3 -(-4)(6-(-3))/(2-(-4)) = -3 +4(9/6) = -3 +6

  x-intercept = 3

-3(4c-2) -2c = -14c+6

Step-by-step explanation:

We need to find the equivalent expression for -3(4c-2) -2c.

First we open the brackets as follows :

-3(4c-2) -2c

= -12c+6-2c

=-12c-2c+6

=-14c+6

So, the equivalent expression is -14c+6.

Answer:

The answer is undefined

Step-by-step explanation:

The slope of the line that passes through points (2, -3) and (2, 13) is not defined.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

The line that passes through points (2, -3) and (2, 13)

The slope 'm' of any straight line is given by:

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

Plug the values to find the slope of the line:

m = (13 + 3)/(2-2) = 16/0 = not defined

Thus, the slope of the line that passes through points (2, -3) and (2, 13) is not defined.
