What is the expression for "the sum of 8 times a number and two"?


8 × 2 N

8( N + 2)

8 N + 2

Answer:

8 possible outcomes

Step-by-step explanation:

I'm going to list all the possibilities and then count them up.

First Word is the wallpaper color, Second is the carpet color.

Red + Purple, Red + Yellow, Blue + Purple, Blue + Yellow, Yellow + Purple, Yellow + Yellow, Green + Purple, Green + Yellow

After counting them up, we get 8. Therefore there are 8 possible outcomes.

Another way is to multiply the possible outcomes for each event together, and you can get the total number of outcomes. For example, in this problem there is 4 wallpaper colors and 2 carpet colors, so when u multiply them u get 8 total outcomes. Hope this helped!

Answer:

x = 7

Step-by-step explanation:

5x - 1 + 8x + 5 = 95

13x + 4 = 95

13x = 91

x = 7

Triangle in 95° so x is

»8x + 5° + 5x - 1° = 95°

»13x + 4° = 95°

»13x = 91°

»x = 91°/13

»x = 7°✅

Answer:

The confidence level is the percentage of times you expect to get close to the same estimate if you run your experiment again or resample the population in the same way. The confidence interval consists of the upper and lower bounds of the estimate you expect to find at a given level of confidence.

Answer:

$30.48

Step-by-step explanation:

after rounding = $30.48

The meal cost $30.48 in total.

Answer:

30 geckos

fraction: [tex]\frac{3}{8}[/tex]

Step-by-step explanation:

Let the numbers of geckos be x, the numbers of anole lizards be y

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

⇒ [tex]5x=3y \left \{ {{a:b=cd}[/tex] → [tex]ad=bc[/tex]

[tex]x+y=80[/tex]

[tex]3x+3y=80\times3[/tex]

[tex]3x+3y=240[/tex]

[tex]3x+5x=240[/tex]

[tex]8x=240[/tex]

[tex]\frac{8x}{8}=\frac{240}{8}[/tex]

[tex]x=30[/tex]

[tex]\frac{30}{80}=\frac{3}{8}[/tex]

Answer:

Step-by-step explanation:

In the given arithmetic series,

To find the sum of the series, we need to find the number of terms (n) at first. So,

[tex]a_{n} = a + (n - 1)d\\38 = 6 + (n - 1) 4\\38 - 6 = 4n - 4\\32 = 4n - 4\\32 + 4 = 4n\\36 = 4n\\36 \div 4 = n\\\boxed{9 = n}[/tex]

Now, let's find the sum of the arithmetic series (Sₙ).

[tex]S_{n} = \frac{n}{2} [2a + (n - 1)d]\\S_{n} = \frac{9}{2} [2*6 + (9 -1)4]\\S_{n} = \frac{9}{2} [12+ (8*4)]\\S_{n} = \frac{9}{2} [12+ 32]\\S_{n} = \frac{9}{2} (44)\\S_{n} = 9*22\\\boxed{S_{n} = 198}[/tex]

21(5m - 3) = 63*9

105m - 63 = 567

105m = 630

m = 6

Answer:

2/21

Step-by-step explanation:

5m=9/21+3/63

5m=27/63+3/63

5m=30/63

5m=10/21

m=10/21/5

m=10/21 x 1/5

m=2/21

The given temperatures of 70 °F, 50 °F, and 35 °F, at the given 3, 3, and

6 days give the following step function;

[tex]\begin{cases}f(x) = 70^{\circ } & \text{ if } 0 \leq x \leq 3 \\f(x) = 50^{\circ} & \text{ if } 3 < x \leq 6 \\ f(x) = 35^{\circ }& \text{ if } 6 < x \leq 12 \end{cases}[/tex]

The temperature at it is fermented in the first three days = 70 °F

From day 3 to 6 the temperature = 50 °F

From day 6 to day 12, the temperature at which it is kept in the freezer = 35 °F

The step function is therefore;

[tex]\begin{cases}f(x) = 70^{\circ } & \text{ if } 0 \leq x \leq 3 \\f(x) = 50^{\circ} & \text{ if } 3 < x \leq 6 \\ f(x) = 35^{\circ }& \text{ if } 6 < x \leq 12 \end{cases}[/tex]

Substitute 63 for y and solve for x. x =8.

Answer:

A. x = 212

Step-by-step explanation:

      This scale is showing us that x + 122 is equal to 334 because the scale is balanced and we can see an equal sign (=) in the center. We will set up an equation and solve for x.

[Equation]

x + 122 = 334

[Subtract 122 from both sides]

x = 212

A. x = 212

Answer:

Step-by-step explanation:

The answer is B, if we were to plug all the values of x with its corresponding value of y into the equation, everything matches up

Answer:

6. [tex]y=2(0.3)^x[/tex]

7. 3, greater than 1, growth, (0,3)

Step-by-step explanation:

General form of an exponential equation:  [tex]y=ab^x[/tex]

(where a is the initial value, b is the growth/decay factor, and x is the independent variable)

If b > 1, the function represents exponential growth.

If 0 < b < 1, the function represents exponential decay.

Therefore, [tex]y=2(0.3)^x[/tex] represents an exponential decay (as 0 < b < 1)

For [tex]y=3(4)^x[/tex]

The y-intercept is when x = 0 ⇒ [tex]y=3(4)^0=3[/tex]

The value of a is 3.  The value of b is greater than 1.  So, the function represents exponential growth.  The y-intercept is (0, 3)

Answer:

T(n) = 7+n

Step-by-step explanation:

A.P. Formula: a(n) = a + (n-1)d

Since a = 8 (given),

and we know 2*[T(8)] = T(16)

We may set up an equation to find d/

2(8+(8-1)d) = 8+(16-1)d

d = 1

Therefore, T(n) = 8 + (n-1)(1) = 7+n

Take the commission rate and move the decimal over to the left twice.

Then you multiply it by the sale price.

Answer:

First, let's just pick an arbitrary number as an example 7.031.

the 1 is in the thousandth place, so we can represent this as [tex]7\frac{31}{1000}[/tex].

This is so because determining what denominator of a decimal number is can be known through what non-zero digits is on the right-most side of the number.

Step-by-step explanation:

Answer:

The third digit after a decimal point is in the "thousandth" place.

Therefore, to convert a decimal that terminates after three decimal places to a fraction, simply write the digits (without leading zeros) as the numerator and 1000 as the denominator.

For example:

[tex]12.345=\dfrac{12345}{1000}[/tex]

[tex]0.932=\dfrac{932}{1000}[/tex]
