Answer:

$28.40

Step-by-step explanation:

First let's find how much they earned from washing the cars. They charged $6 for each car and washed 22 so 6x22=$132 from washing cars. After that they earned 10 more dollars so we have to add that. 132+10=$142 earned in total. Then we have to divide this total income between all of the girls. 142/5=$28.40 for each girl.

Considering the t-test applied, the number of degrees of freedom is given by:

d. 10.

For a sample of size n, the number of degrees of freedom is given by:

df = n - 1

When there are m samples, the amount of degrees of freedom is m multiplied by the sum of degrees of freedom of each sample.

In this problem, there are 2 samples with 6 - 1 = 5 df, hence:

2 x 5 = 10.

Option d is correct.

2 pint = 24 serving

The probability of randomly selected students who will be absent no more than one day is 0.92. Option D is correct.

The probability is defined as the number of favorable occurrences of an event.

Given the probability distribution of the number of absence for one week,

x:            0         1         2         3       4      5

P(X):    0.78    0.14    0.03    0.01    0    0.04

We know that the probability of any event is always less than equal to 1. We can write that,  [tex]P(x\leq 1)[/tex].

So the probability of randomly selected students who will be absent no more than one day is calculated as given below.

[tex]P = P (x=0) + P(x=1)\\P = 0.78 + 0.14[/tex]

[tex]P = 0.92[/tex]

Hence we can conclude that the probability of randomly selected students who will be absent no more than one day is 0.92. Option D is correct.

x/3=how much the tickets cost

Step-by-step explanation:

If each of the four friends pays $7.04, the equation would be set up like this: 7.04*4=28.16. This means the total cost for tickets is 28.16. If the total cost for three tickets is 28.16, just divide the total cost by how many tickets were purchased. 28.16/3=9.39. This means one ticket cost 9.39.

[tex]\longrightarrow \sf £ \:9.4 [/tex]

[tex]\leadsto[/tex]Money paid by 1 friend = £ 7.05

[tex]\leadsto[/tex]Money paid by 4 friend = £ 7.05 × 4

[tex] \quad\quad\quad\quad\quad\quad\quad\quad\quad\quad[/tex]= £ 28.2

This is equal to cost of 3 tickets

[tex]\leadsto[/tex] Cost of 3 tickets = £ 28.2

[tex]\leadsto[/tex] Cost of 1 ticket = £ 28.2 ÷ 3

[tex]\quad\quad\quad\quad\quad\quad\quad\quad\quad[/tex]=£ 9.4

Thus , each ticket cost £ 9.4 .

Answer:

D)  [tex]x=\frac{5}{3}[/tex] and [tex]x=-4[/tex]

Step-by-step explanation:

Factor by grouping

[tex]3x^2+7x-20=0\\\\3x^2+12x-5x-20=0\\\\3x(x+4)-5(x+4)=0\\\\(3x-5)(x+4)=0[/tex]

Solve each factor using the Zero Product Property

Answer:

220°

Step-by-step explanation:

[tex]\angle PQM [/tex] is inscribed in the [tex]\widehat{PQM}[/tex] and [tex]\widehat{PNM}[/tex] is intercepted by it.

Therefore, by inscribed angle theorem:

[tex]m\angle PQM =\frac{1}{2}\times m\widehat{(PNM)}[/tex]

[tex]\implies 110\degree =\frac{1}{2}\times m\widehat{(PNM)}[/tex]

[tex]\implies 110\degree \times 2= m\widehat{(PNM)}[/tex]

[tex]\implies m\widehat{(PNM)}= 220\degree [/tex]

[tex]\\ \rm\Rrightarrow m<PQM=1/2m\overset{\cap}{PNM}[/tex]

[tex]\\ \rm\Rrightarrow m\overset{\cap}{PNM}=2m<PQM=2(110)=220°[/tex]
