You randomly choose a marble from a jar. The jar contains 4 red marbles, 10 blue marbles, 7 green marbles, and 6 yellow marbles. Find the probability of the event. Not choosing a blue marble.

Answers

Answer 1

Answer:

The probability of not choosing a blue marble is 17/27.

What is probability?

Probability deals with the occurrence of a random event. The chance that a given event will occur. It is the measure of the likelihood of an event to occur.The value is expressed from zero to one.

For the given situation,

Number of red marbles = 4

Number of blue marbles = 10

Number of green marbles = 7

Number of yellow marbles = 6

The event is the probability of not choosing a blue marble is

⇒ $(red+green+yellow)/(Total marbles)$

⇒ $(4+7+6)/(27)$

⇒ $(17)/(27)$

Hence we can conclude that the the probability of not choosing a blue marble is 17/27.

Answer 2

Answer:

Answer:

17/27

Step-by-step explanation:

Since there are 10 blue marbles, and 27 total marbles, the probability of not choosing a blue marble is 17/27 because you subtract the amount of blue marbles (10) from the amount of total marbles (27).

(4x2 – x + 3) – 7

(4x2 – x + 3)(x – 7)

Answers

The correct answer is 4(x-7)²-(x-7)+3.

Explanation:
When we find (t*s)(x), that is the same as t(s(x)). To evaluate this, we take the value of s(x), x-7, and substitute it in for every x in t(x). Instead of 4x², we have 4(x-7)²; instead of -x, we have -(x-7). This gives us 4(x-7)²-(x-7)+3.

Answer:

$(4x^2-x+3)(x-7)<strong>$

D is the correct option.

Step-by-step explanation:

We have been given that

$s(x)=x-7\text{ and }t(x)=4x^2-x+3$

We have to find $(t\cdot x)$

which means we have to find the product of these two expressions.

We can rewrite $(t\cdot x)$ as $t(x)s(x)$

Therefore, we have

$(t\cdot x)\n\n=t(x)s(x)=(4x^2-x+3)(x-7)$

Hence, the equivalent expression is

$(4x^2-x+3)(x-7)$

D is the correct option.

Answers

Answer:

$\displaystyle y =(1)/(2)x+5$

Step-by-step explanation:

Equation of the line

The slope-intercept form of a line is given by:

$y=mx+b$

Being:

m = the slope of the line

b = the y-intercept

We can also use the point-slope form of the line:

$y - k=m(x-h)$

Being:

(h,k) = A point that belongs to the line

Two lines of slopes m1 and m2 are perpendicular if:

$m_1.m_2=-1$

We are given the line:

$y=-2x+5$

Whose slope is m1=-2

Thus, the perpendicular line has a slope of:

$\displaystyle m_2=-(1)/(m_1)$

$\displaystyle m_2=-(1)/(-2)$

$\displaystyle m_2=(1)/(2)$

The required line contains the point (-8,1), thus the equation is:

$\displaystyle y - 1=(1)/(2)(x+8)$

Removing the parentheses:

$\displaystyle y - 1=(1)/(2)x+(1)/(2)\cdot 8$

Adding 1:

$\displaystyle y =(1)/(2)x+(1)/(2)\cdot 8+1$

Operating:

$\displaystyle y =(1)/(2)x+4+1$

$\mathbf{\displaystyle y =(1)/(2)x+5}$

Alaina bought a square frame for her desk that has an area of 81 square inches. What is the perimeter of the frame? (answer should be a number only)

Answers

Given:

Area of a square frame = 81 square inches.

To find:

Perimeter of the frame.

Solution:

Let length of each side of the frame = a inches.

Area of square frame is

$Area=a^2$

$81=a^2$

Taking square root on both sides,

$\pm√(81)=a$

$\pm 9=a$

Side length cannot be negative. So, a=9 inches.

Perimeter of frame is

$Perimeter=4a$

$Perimeter=4(9)$

$Perimeter=36$

Therefore, the perimeter is 36 inches.

Final answer:

The perimeter of the frame is 36 inches.

Explanation:

To find the perimeter of a square, we need to know the length of its sides. Since the area of the frame is given as 81 square inches, we can find the length of one side by taking the square root of the area. The square root of 81 is 9, so each side of the frame measures 9 inches.

Since a square has four equal sides, we can find the perimeter by multiplying the length of one side by 4. Therefore, the perimeter of the frame is 9 inches x 4 = 36 inches.

Sal and two of his friends rent an apartment together. Their total cost to move in included first months rent, last months rent and a security deposit of $1,200. If Sal paid a total of $1,000 to move in, how much is his share of the rent each month?.

Answers

according to the problem the payment Sal did correspond to
(2 rent + 1200)/3 = 1000
2 rent + 1200 = 3000
2 rent = 1800
rent = 900
this means that
rent = $900

Answer:

according to the problem the payment Sal did correspond to

(2 rent + 1200)/3 = 1000

2 rent + 1200 = 3000

2 rent = 1800

rent = 900

this means that

rent = $900
