Answer: 1.92 x 10^8

Step-by-step explanation:

Answer: 504

Step-by-step explanation:

Area: 4 triangles + square

Triangle area = 1/2 x b x h

Square = side x side

4(1/2 x 12x 15) + 12x12

= 504

Answer:

[tex]\frac{115\pi }{6} \\or\\19.16666667\pi[/tex]

Step-by-step explanation:

Arc length is [tex]2\pi r*\frac{o}{360}[/tex]

r is 46 theta is 75

[tex]2(46)\pi *\frac{75}{360} \\92\pi *\frac{75}{360} \\\frac{6900\pi }{360} \\\frac{115\pi }{6} or 19.166666667\pi[/tex]

Step-by-step explanation:

there are a total of 6 distinct choices.  4 of the six , are NOT red.

so 4/6 or 2/3

P(not red) = 2/3

Answer:

i dont know if am completely right since your question doesn't really make sense but i think its y = 10

Step-by-step explanation:

Remove the "y" -  -5 + 20

Add up - -5 + 20 = 15

Add the other -5y -   -5 + 15 = 10

Re-add the "y" -  10y

y = 10

Answer:

1 10/17

Step-by-step explanation:

make 45 a fraction by putting a denominator of 1

3/85 * 45/1

3*45 = 135

85*1 = 85

Simplify 135/85 = 1 10/17

Answer:

1/2

Step-by-step explanation:

The Rational Root Theorem says that any rational root has

1. a numerator that is a factor of the constant term

2. a denominator that is a factor of the leading coefficient (that's attached to the highest-power term)

Numerator:  [tex]\pm 1[/tex]

Denominator: [tex]\pm 2[/tex]

That means there are only two possible rational roots: [tex]\pm \frac{1}{2}[/tex]

Try them both by plugging them into the polynomial.

[tex]2\left(\frac{1}{2}\right)^3 + 3\left(\frac{1}{2}\right)^2 -1= \frac{1}{4}+\frac{3}{4}-1 =0[/tex]

Aha!  The negative one-half value does not produce 0

Answer:

The missing marks are 3, 3, and 5.

Step-by-step explanation:

Since the mode is 3, that means it's the number that occurs most often. The numbers 1 and 2 occur twice so there must be at least 3 3's on the list. But since the mean is 2.9, the third mark cannot be a 3 because it will make the mean only 2.7 so the 3rd mark can be either a 4 or a 5. Using 5 will make the mean 2.9. I take it that you know how to make a bar graph for this problem.

Answer:

ŷ = -0.47876X + 11.17724

$6.4

Step-by-step explanation:

Given the data :

Car Age (years) Selling Price ($000) Car Age (years) Selling Price ($000)

1 9 8.1 7 8 7.6

2 7 6 8 11 8

3 11 3.6 9 10 8

4 12 4 10 12 6

5 8 5 11 6 8.6

6 7 10 12 6 8

The estimated regression equation using a linear regression calculator is :

y = -0.47876X + 11.17724

With - 0.47876 being the slope ; and 11.17724 being the intercept

y = predicted variable (price of car) ; x = predictor variable (Age of car)

Selling price of a 10 year old car : x = 10

ŷ = -0.47876(10) + 11.17724

Price = 6.38964

About 6.4(000) dollars ($6,400)

According to the regression equation : The starting price of cars is about $11.18 (intercept) with the proved of cars declining by a value of $0.479(negative slope value) each year.

Answer:

Step-by-step explanation:

 To find the area of a rectangle in square inches  simply multiply your measurements for length and width to determine the area of your square or rectangular area in square inches. For example, let's say that, for a rectangular area, you measure a length of 4 inches and a width of 3 inches. In this case, the area within your rectangle is 4 × 3 = 12 square inches.

The shape above is a trapezium, so we are going to use the formula for the area of a trapezium which is,

[tex]area = (\frac{a + b}{2} )h[/tex]

Plugging in our values,

[tex]area = ( \frac{2 + 8}{2} ) \times 3 = ( \frac{10}{2} ) \times 3 = 5 \times 3 = 15 {cm}^{2} [/tex]

So the area will be

[tex]15 {cm}^{2} [/tex]

FD =  

FD = 252.77

FD ≈ 252.8 feet

Answer:

[tex]y = - 3 {x}^{2} + bx + c \\ when \: (1,0) \\ 0 = - 3( {1})^{2} + b(1) + c \\ 0 = - 3 + b + c \\ b + c = 3 - - - (.) \\ at \: (0,0) \\ 0 = c \\ c = 0 \\ hence \: b = 3[/tex]
