Fiesta28 [93]

Answer:

Hence the best estimate is population with correct option is 74% and

the value for x=148

Step-by-step explanation:

Given:

A sample of 200

Of which 148 prefer brand new coffee

To Find:

Which statement is true?

Solution:

n=200

x=148

remaining 52 prefer old ones .

So estimate population proportion,

p=x/n

p=148/200

p=0.74

p=74 %

Now, when x=52

p=x/n,

p=52/200

p=0.26

p=26%

There is no option for 52 and 24 %

Hence x=148 and p=74%.

Consider, please, this solution/explanation:
1. suppose, that number of cars is 'x', numbers of buses is 'y'.
2. according to the condition 'a total of 32', it means that x+y=32. This is the 1st equation.
3. according to the condition in one car are 3x persons, in one bus are 27y persons, and totaly 3x+27y=408 people. This is the 2d equation.
4. if to solve the system of two equations:
$\left \{ {{x+y=32} \atop {3x+27y=408}} \right. \ =\ \textgreater \ \ \left \{ {{x=19 (cars)} \atop {y=13(buses)}} \right.$

Answer: 13 - b., 19 - c.

A basketball player makes 75% of her free throws. If she made 84 free throws this season, how many has she attempted?

myrzilka [38]

If you would like to know how many free throws did a basketball player attempted, you can calculate this using the following steps:

75% of x is 84
75% * x = 84
75/100 * x = 84
x = 84 * 100 / 75
x = 112 free throws

The correct result would be 1<span>12 free throws.</span>

A six sided die is rolled and a spinner with 5 equal spaces labeled A-E is spun. Find the P(rolling

natulia [17]

Answer:

1 / 30

Step-by-step explanation:

For a six - sided die :

Sample space = (1, 2, 3, 4, 5, 6)

P(rolling a 1) = required outcome / sample space = 1/6

Sample space for spinner = (A, B, C, D, E)

P(spinning A ) = required outcome / sample space = 1/5

P(spinning A) = 1 / 5

P(rolling a 1 and spinning A) = P(rolling a 1) * P(spinning A) = 1/6 * 1/5 = 1 / 30
