6 0

SOLUTION:

Solving for x -

4 = 5x + 3y

5x + 3y = 4

5x = 4 - 3y

x = ( 4 - 3y ) / 5

Solving for y -

4 = 5x + 3y

5x + 3y = 4

3y = 4 - 5x

y = ( 4 - 5x ) / 3

Hope this helps! :)

The answer is 81.1 because since the 9 place value above 5, you round the number in front of it to 1. so the answer is 81.1. I hope that helps.

A test consists of 10 true or false questions. To pass the test a student must answer at least eight questions correctly. If the

forsale [732]

<h3>The probability of student passing the quiz with at least 50% of the questions correct is 0.05457.</h3>

Step-by-step explanation:

Here, the total number of T/F question = 10

The minimum answers needed correctly answered = 8

So, student needs to answer at least 8 questions correctly.

Here, the possibility of answering a question correctly = $(\frac{1}{2})$ = p = 0.5

Also, the possibility of answering a question wrong = $(\frac{1}{2})$ = q = 0.5

Now, to pass he needs to answer 8 or more ( 8 , 9 or 10) answers correctly.

P(answering 8 correct answer) = $^{10}C_8(p)^8(q)^2 = ^{10}C_8(0.5)^8(0.5)^2 = 0.0439$

P(answering 9 correct answer) = $^{10}C_9(p)^9(q)^1 = ^{10}C_9(0.5)^9(0.5)^1 = 0.0097$

P(answering 10 correct answer) = $^{10}C_{10}(p)^{10}(q)^0 = ^{10}C_{10}(0.5)^{10}(0.5)^0 = 0.00097$

So, the total Probability = P(8) + P(9) + P(10)

= (0.0439) + (0.0097) + (0.00097)

= 0.05457

Hence, the probability that the student passes the quiz with at least 8 of the questions correct is 0.05457.

The graph shows the relationship between the hours a soccer team practiced after the season started and their total practice tim

Sergio [31]

Answer:

6 hours

Step-by-step explanation:

<u><em>The picture of the question in the attached figure</em></u>

Let

x ----> the hours a soccer team practiced after the season started

y ----> the total practice time for the year in hours

we know that

The y-intercept of a linear equation is the value of x when the value of y is equal to zero

In the context of this problem, the y-intercept is the total practice time before the season began (the value of x is equal to zero)

Looking at the graph

The y-intercept is the point (0,6)

therefore

the total practice time before the season began is 6 hours

Solve -7<3x+2<5<br> (Multiple choice, picture added)

pishuonlain [190]

$\\ \sf\longmapsto -7$

Substract 2 from all sides

$\\ \sf\longmapsto -7-2$

$\\ \sf\longmapsto -9$

Divide all sides by 3

$\\ \sf\longmapsto \dfrac{-9}{3}$

$\\ \sf\longmapsto -3$

Option A is correct
