a theater has 49 seats in the first row, 52 seats in the second row, 55 seats in the third row, and so on. how many seats are there in row 20

Answers

Answer 1

Answer:

106

Step-by-step explanation:

this question represents an arithmetic sequence problem where you can use this formula: a(n) = a(1) + d(n-1)  where 'n' is value you're solving for, a(1) is the initial value, and 'd' is the common difference

a(20) = 49 + 3(20-1)

= 49 + 3(19)

= 49 + 57

= 106

Step-by-step explanation:

Lipids provide much of the dietary energy in the bodies of infants and young children. There is a growing interest in the quality of the dietary lipid supply during infancy as a major determinant of growth, visual and neural development, and long-term health. An article reported the following data on total polyunsaturated fats (%) for infants who were randomized to four different feeding regimens: breast milk, corn-oil-based formula, soy-oil-based formula, or soy-and-marine-oil-based formula. (Use i= 1, 2, 3, and 4 respectively.)
Sample Regimen Sample Size Sample Mean Sample SD
Breast milk 15 42.9 1.3
CO 17 43.1 1.5
SO 8 43.7 1.2
SMO 14 43.9 1.2
What assumptions must be made about the four total polyunsaturated fat distributions before carrying out a single-factor ANOVA to decide whether there are any differences in true average fat content?
a. The distribution of polyunsaturated fat percentages for each of the four regimens must be uniform with equal variances.
b. The distribution of polyunsaturated fat percentages for each of the four regimens must be normal with unequal variances.
c. The distribution of polyunsaturated fat percentages for each of the four regimens must be normal with equal variances.
d. The distribution of polyunsaturated fat percentages for each of the four regimens must be binomial with unequal variances.

Answers

Answer:

c. The distribution of polyunsaturated fat percentages for each of the four regimes must be normal with equal variance's.

Step-by-step explanation:

Single factor ANOVA is used for testing the null hypothesis with same mean of several population. The alternative hypothesis is set against the null hypothesis in order to identify whether the null statement is correct or it will be rejected.

To multiply a decimal number by 102, move the decimal point

Answers

Answer:

two digits to the right

Step-by-step explanation:

When multiplying a decimal by 102 you would need to move the decimal point two digits to the right. This is because we are multiplying by a hundred number. When multiplying any whole positive number by a decimal, we need to move the decimal point to the right one less than the amount of digits that the positive whole number has. For example, a thousand (1000) has 4 digits so we move the decimal point of the product to the right by 3.

Examples:

102 * 0.02 = 2.04

1000 * 0.02 = 20

10000 * 0.02 = 200

The point-slope form of the equation of a line can be a useful place to start.

  y -k = m(x -h) . . . . . line with slope m through point (h, k)

  y +20 = 3(x +4) . . . . with given numbers filled in

  y = 3x +12 -20 . . . . eliminate parentheses, subtract 20

Evaluate $3x^y + 4y^x$ when $x=2$ and $y=3$.

Answers

Answer:

60

Step-by-step explanation:

Given,

x = 2

y = 3

= 3 ( 2 )^3 + 4 ( 3 )^2

= 3 ( 8 ) + 4 ( 9 )

= 24 + 36

2. 2/1 so run is 1

3. its positive since slope is positve

money market: $1000stock: $238,500mutual fund: $228,500

Step-by-step explanation:

We can let x and y represent the amounts invested in the stock and mutual fund, respectively. Then the amount invested in the money market account was (468000 -x -y). Two relations can be written.

  x = y + 10000 . . . . . 10,000 more was invested in stock than in mutual funds

  0.035(468000-x-y) +0.04(x) -0.03(y) = 2720 . . . . first-year return

Collecting terms in the second equation gives ...

  0.005x -0.065y +16380 = 2720

  -x + 13y = 2732000 . . . . . . subtract 16380, multiply by -200

  12y -10000 = 2732000 . . . . substitute for x using the first equation

  y = 2742000/12 = 228,500 . . . . solve for y

  x = 228,500 +10,000 = 238,500 . . . . . find x from the first equation

  468,000 -x -y = 468,000 -467,000 = 1,000 . . . . find the money market amount

Pierre invested $1000 in the money market account, $238,500 in the stock, and $228,500 in the mutual fund.
