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

Answer:

A. P(3/4)

Step-by-step explanation:

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:

x = 3

Step-by-step explanation:

4(6x - 7) = 44

divide both sides by 4

6x - 7 = 11

add 7 to both sides

6x = 18

divide both sides by 6

x = 3

Area of triangle = 1/2 x base x height

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

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.

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

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:

$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.
