a. (-oo, 0)

Answer:

A) 5; B) 32; C) 3; D) 14; E) 1/3

Step-by-step explanation:

Answer:

1. 5

2. 42

3. 3

4. 14

5. 0.3333

Step-by-step explanation:

Third Grade:

8 x 5 = 40

8 + 42 = 40

21 ÷ 7 = 3

21 - 14 = 7

---------------------------21 • x = 7

Which can be written as:

21x = 7

To solve the equation above, we need to remove the 21 on the left side to make the x alone. To do that, we divide both sides by 21.

21x/21 = 7/21

21x/21 is x and 7/21 is 0.3333 which means our equation will look like this:

x = 0.3333

Thus, the answer to "21 times what equals 7?" is 0.3333.

From the sample used to find out what psychology majors would join the club and if it is biased, we can say that;

- Yes, the sampling method is biased.

- The likely direction of the bias is because you only asked 5 people which

is  not a significant percentage of those offering psychology majors and as

such the 4 out of 5 gotten is likely going to be an over estimation of those

who are willing to pay to join this club.

We are told that;

Therefore, this would lead to sampling bias and thus the sample is biased.

Answer

-10

Step-by-step explanation:

-8w-7=9

add 7 to both sides

-8w=16

divide by negative 8 on both sides

w=-2

w-8=-10

On simplifying,

-8w - 7 = 9

-8w = 16

w = -2

then,

= w - 8

= -2 - 8

= -10.

Answer:

yes he will

Step-by-step explanation:

Hence, if his parents giving him $[tex]35[/tex] per week then he can purchase his game system.

What is the simplification?

Simplification is reducing the expression/fraction/problem in a simpler form. It makes the problem easy with calculations and solving.

Here given that,

Joe has $[tex]180[/tex] in his bank account he wants to buy a new gaming system for $[tex]250[/tex] in two weeks his parents have offered to lend him money if he needs it he gets $[tex]20[/tex] a week for a allowance

So,

His account saving is $[tex]180[/tex].

He wants to purchase a game system which costs $[tex]250[/tex].

His parents giving $[tex]20[/tex] per week. So iin two weeks it is [tex]20(2)=40[/tex]$.

Then , the total savings he had [tex]180+40=220[/tex]$

So he needs [tex]30[/tex]$ more to purchas his game system

If his parents giving him $[tex]35[/tex] per week then in two weeks it would be [tex]35(2)=70[/tex]$.

Then his total savings are

[tex]180+70=250[/tex]$.

Hence, if his parents giving him $[tex]35[/tex] per week then he can purchase his game system.

Answer:

1, 4, 5, 6

Step-by-step explanation:

1 - Division is considered a fraction, subjected to fraction as division also. Since - 5/17 is basically considered -5/-17 (via 4), 1. is a choice.

4 - As explained, - 5/17 is -5/-17, so this is also a choice.

5,6 - Whether the negative symbol is in the numerator and/or denominator, it is officially thought overall to be - 5/17.

Answer:

4.140393356

Step-by-step explanation:

Mean = (3+4+5+7+10+12+15) / 7 = 8

Count = 7 numbers

Sum of the numbers = 56

Each number minus the mean =

(3-8=-5)(4-8=-4)(5-8=-3)(7-8=-1)(10-8=2)(12-8=4)(15-8=7)

Now square of each of these numbers:

25+16+9+1+4+16+49 = 120

Variance = 120/7 = 17.14285714

Standard deviation = square root of the variance

Sqrt 17.14285714 = 4.140393356

Answer:

The answer is in the picture above

Step-by-step explanation:

the derivative of an inverse function is

1/f'(f^-1(x))

f'(x) = -6x²

f^-1(7) is solving the original function equation for x under the knowledge that y = 7

7 = 5 - 2x³

2 = -2x³

-1 = x³

=>

x = -1

f'(-1) = -6×(-1)² = -6×1 = -6

so,

(f^-1)'(7) = -1/6

The rotation that the triangle DEF underwent is defined as follows:

180º around the origin.

A rotation is one example of transformation that a function can undergo, along with transformation, compression, stretching, dilation or reflection.

A rotation changes the inclination of the figure, and the rules for each rotation are given as follows:

In this problem, the coordinates are given as follows:

Hence the rule is:

Answer:

8 inches

Step-by-step explanation:

Height = Volume / Base Area = 301.44 / 37.68 = 8

Step-by-step explanation:

this line goes through the points (0, -3) and (4, 0).

so, the y-axis intercept is at y = -3.

therefore, the equation has to end with "- 3".

the slope (the factor of x in the equation) is the y/x ratio of the changes of y and of x when going from one point to the other :

x changes by 4 positive units (from 0 to 4), and y changes by 3 positive units (from -3 to 0).

so, the slope is 3/4.

and so, the equation is

y = (3/4)x - 3
