Answer:

  A: f(x)=2x^2 +12x +10

  B: f(0) = 10

Step-by-step explanation:

<u>Part A</u>:

f(0) is a constant in the equation if the form is such that for x=0, all terms are zero except one of them. Standard form is one such form. This is the equation in standard form:

  f(x) = 2x^2 +12x +10

__

<u>Part B</u>:

  f(0) = 0 + 0 + 10

  f(0) = 10

Here are the prices of five new pairs of hockey skates, in dollars: 59, 60, 65, 99, 175. The standard deviation is about $49. If
Phoenix [80]

Answer:

The standard deviation of the new data will be increased as compared to the previous standard deviation of the data.

Step-by-step explanation:

The prices are given to be : 59, 60, 65, 99, 175

Standard deviation = $49

Now, if we add or subtract any constant value to each of the terms then the standard deviation remains unchanged.

But, we add a new price in the given data that is $450

\text{New standard deviation = }\sqrt{\frac{\sum (\bar{x}-x_i)^2}{n}}\\\\\bar{x}\text{ is the mean of data after adding 450 and}\\x_i\text{ are the price values of the sample data}

Hence, Standard deviation is calculated to be 139.5

Therefore, the standard deviation of the new data will be increased as compared to the previous standard deviation of the data.

A consumer wanted to find out how accurate Siri (an Apple digital assistant) is, so he asked questions on general facts and reco
Mashcka [7]

Answer:

The answer is "0.869"

Step-by-step explanation:

Number of sample (n) = 84

Number of correct response (X) = 73

Calculating the Sample proportion:

Formula:

\text{Sample proportion}=\frac{\text{number of sample}}{\text{correct responses}}

                              =\frac{n}{X}\\\\= \frac{73}{84} \\\\=0.869

Select ordered pairs that's satisfy the function Y=-6x-2
sveticcg [70]
Basically, u just sub in any number for x and solve for y

y = -6x - 2.....lets say x = 0
y = 6(0) - 2
y = -2....so when x is 0, y is -2 .....(0,-2)

y = -6x - 2....lets say x = 1
y = -6(1) - 2
y = -6 - 2
y = -8.......another solution is (1,-8)

y = -6x - 2....lets say x = 2
y = -6(2) - 2
y = -12 - 2
y = -14....another solution is (2,-14)

y = -6x - 2....lets say x = 3
y = -6(3) - 2
y = -18 - 2
y = -20...another solution is (3,-20)

I think u get the idea now :)
