Answer:

A. P(3/4)

Step-by-step explanation:

Answer:

7.04*4=x

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:

3rd option

Step-by-step explanation:

the explicit formula for a geometric sequence is

[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]

where a₁ is the first term and r the common ratio

here a₁ = - 4 and r = [tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{12}{-4}[/tex] = - 3 , then

[tex]a_{n}[/tex] = - 4 [tex](-3)^{n-1}[/tex]

Answer:

Peter.

Step-by-step explanation:

I’m assuming from context (your question was written poorly) you’re asking which student walked farther. This would be Peter. Why? Carol walked only 3/5 miles of the way to school, which would be .6 or .60

Peter walked .65 miles to school which is more than .60

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.

Answer:

p = 33/100 = 33%

Step-by-step explanation:

p (probability) = 1.00 - [variables]

p = 1.00 - (0.12 + 0.07 + 0.05 + 0.28 + 0.15)

p = 1.00 - 0.67

p = 33/100

y=-3(x-2)

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.

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.

The volume of the triangular prism = [tex]V = (base-area)*height[/tex]

Thus the volume is [tex]\\V = (\frac{1}{2} *3*4) * 7 = 6 * 7 = 42[/tex].

Thus the volume is 42 cubic km.

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

[tex]3x-5=0\\\\3x=5\\\\x=\frac{5}{3}[/tex]

[tex]x+4=0\\\\x=-4[/tex]

Thus, [tex]x=\frac{5}{3}[/tex] and [tex]x=-4[/tex] are the solutions
