Answer:

chisquare = 31.667

degree of freedom = 2

Step-by-step explanation:

Formula for chisquare test =  (O-E)²/E

total number observations= 60 + 25 + 15 = 100                  

Estimated E,

80% x 100 = 80

15%x100 = 15

5% x 100 = 5

chisquare =

\frac{(60-80)^{2} }{80} +\frac{(25-15)^{2} }{15}+\frac{(15-5)^{2} }{5}\\

= 5 + 6.67 + 20

= 31.667

from the calculation above the value of the chisquare statistic = 31.67

the degree of freedom is the number of samples in the test  n - 1

= 3-1

= 2

I have solve this question also in a tabular form to aid understanding in the file i uploaded.

thank you and good luck!

William and Debra Pierce are celebrating their 20th anniversary by having a reception at a local reception hall. If the receptio
Nataly [62]

The greatest number of people that they may invite and still stay within their budget is 130 people.

The standard form of a linear equation is given by:

y = mx + b

Where y is a dependent variable, x is an independent variable, m is the slope of the line (the rate of change), b is the y intercept (that is the initial value of y).

Let y represent the budget for x number of people.

Since the reception hall charges a $80 cleanup fee plus $34 per​ person, hence this can be represented by the function:

y = 34x + 80

They have budgeted $4,500 for their reception. Therefore the greatest number of people can be found from:

4500 = 34x + 80

34x = 4420

x = 130 people

Therefore the greatest number of people that they may invite and still stay within their budget is 130 people.

vesna_86 [32]

Answer:

1/6

Step-by-step explanation:

number cube 6 faces less than 2, only 2 possibilities, leaving us with a fraction of 2/6=1/3

tails is a 50 percent chance or 1/2

3/6 time 2/6

equals:

1/6

the probability of rolling a number less than 2 and flipping tails on a coin is 1/6

find probability of event a: number cube and multiply it by probability of event b: coin

Compare the structure of the two
Ipatiy [6.2K]

Answer:

  1. single term
  2. sum of 4 terms, some of which can be expanded further

Step-by-step explanation:

1. 3x

This is a single term with one variable of the first degree.

__

2. 4x + 9(2x + 1) x² + 6(-2x + 1) - 3(7 + x?)

This is a sum of 4 terms, some of which can be expanded:

  • 4x
  • 9(2x+1)x^2  ⇒  18x^3 +9x^2
  • 6(-2x +1)  ⇒  -12x +6
  • -3(7+x?)  ⇒  -3x? -21

The expression can be simplified by combining like terms.
