Answer:

[tex]P(x = 5) = 0.2441[/tex]

Step-by-step explanation:

Given

[tex]p = 0.48[/tex] --- proportion that have very little confidence

[tex]n = 10[/tex] --- sample

Required

Determine the probability that exactly 5 have very little confidence

This question will be solved using binomial probability:

[tex]P(x) = ^nC_xp^x(1-p)^{n-x}[/tex]

In this case: x = 5.

So, we have:

[tex]P(x = 5) = ^{10}C_5*0.48^5(1-0.48)^{10-5}[/tex]

[tex]P(x = 5) = ^{10}C_5*0.48^5*0.52^5[/tex]

[tex]P(x = 5) = 252*0.48^5*0.52^5[/tex]

[tex]P(x = 5) = 0.2441[/tex]

They had a balloon fight for 1 hour

They played in the hose for 30 minutes

The water fight ended at 1:45 pm minus 1 hour 30 minutes if play = 12:15 pm start time

Answer:

A

Step-by-step explanation:

You convert each fraction to have the same decimal to find the LCD of both denominators

4, 8, 12, 16, 20 and 5, 10, 15, 20 = both of them have 20 in common

You multiply the numerator and denominator by 5 for 2 3/4 and for 5 4/5 you multiply both the numerator and denominator by 4

2 15/20 and 5 16/20

Subtract them and their is your answer

Answer:

y=mx+b

so

y=8x+3. the second answer choice

Answer:

y=8x+3

Step-by-step explanation:

we are given the slope (m) as 8 and the y intercept (b) as 3.

The given options are in y=mx+b format.

Use your given information to write the equation in y=mx+b form

we know that m (slope) is 8. The equation so far is y=8x+b

we know that b (y intercept) is 3. So the equation of the line is y=8x+3

Question:-

Find the area of an equilateral triangle with side length = 9cm correct upto one decimal place.

_______________________________________________

Solution:-

In an equilateral triangle all sides are equal.

Let s = side length = 9 cm

Then, area of equilateral triangle is given as:

A = (√3/4)s²

Putting the value of s here,

A = (√3/4) * (9 cm)²

=> A = (√3/4) * 81 cm²

=> A = √3 * 20.25 cm²

We know that, √3 = 1.732

=> A = 1.732 * 20.25 cm²

=> A = 35.073 cm²

Rounding to one decimal place,

=> A = 35.1 cm²

_______________________________________________

The answer is 35.1 cm².

Answer:

Number of rooms reserved for the students are - 90 .

Step-by-step explanation:

Firstly ,

As we know 60% of the 600 students went on the trip,

Then ,

Number of students went on the trip = 60% of 600

                                                          = [tex]\frac{60}{100}\times600[/tex]

                                                        = 360

Now ,

Given - One room is reserved  for 4 students ,

Therefore , Number of rooms for 360 students = [tex]\frac{360}{4}[/tex]

                                                                             = 90

Hence , the answer is  90 rooms reserved for the students.

Answer:

4/45

Step-by-step explanation:

The sum of angles in a triangle is 360 degrees

If the angle measures 32 degrees, the fraction can be represent as 32/360

32/360 has to be converted to its simplest form. To this divide both the numerator and the denominator by 8. This gives 4/45

Answer:

it stays the same

Step-by-step explanation:

if it was -3.3 then it would change to 3.3 but because it is already in the positives it stays a positive plz double chesk if needed tho

Answer:

[tex]3.3[/tex]

Step-by-step explanation:

Absolute value expresses the distance of a number from 0.

For this reason, no matter if the number is negative or positive, the absolute value of it will always be positive.

In this case, it is simply [tex]|3.3|=3.3[/tex].

Answer:

20

Step-by-step explanation:

vertical angles are equal. meas. of angle a = meas. of angle b

x=5x-80

x+80=5x

80=4x

20=x

Answer:

A = 80

Step-by-step explanation:

If they are vertical angles, they are equal.

5x - 80 = x                      Add 80 to both sides

5x - 80 + 80 = x + 80

5x = x + 80                     Subtract x from both sides

5x - x = x - x + 80

4x = 80                           Divide by 4

4x/4 = 80/4

x = 20

Answer:

4

Step-by-step explanation:

The slope of the line is given. It is 4. Use the equation y=mx+b to answer the other questions.

Substitute 1 in for y, 4 in for m, and 2 in for x and solve for b. The equation would look like 1=4(2)+b.

Solving that equation will give you b=-7

That means the y-intercept is -7.

The equation would then be y=4x-7

Answer:

-2/7

Step-by-step explanation:

solve for x so -12+ 8 = 30x - 16x so -4 = 14x so x = -4/14, so x = -2/7

Answer:

x=-2/7

Step-by-step explanation:

you have to let x be on one side so you subtract -30x to each side.

16x-30x-12=30x-30x-8

-14x-12=-8

now you gotta add 12 to each sides to delete -12.

-14x-12+12=-8+12

-14x=4

divide -14/14x=14/4

-x=2/7

x=-2/7

Answer:

-2.8

Step-by-step explanation:

Given that:

Mean, μ = 78

Standard deviation, σ = 5

Omar's score, x = 64

The Zscore of Omar's score :

Zscore = (x - μ) ÷ σ

Zscore = (64 - 78) / 5

Zscore = - 14 / 5

Zscore = - 2.8

Hence, Omar's exam score is - 2.8

Answer:

-2.8 is correct

Answer: B

Step-by-step explanation:

Applying limits, it is found that the end behavior of the graph is:

B. As [tex]x \rightarrow \infty, h(x) \rightarrow -\infty[/tex], and as [tex]x \rightarrow -\infty, h(x) \rightarrow \infty[/tex].

The function is:

[tex]h(x) = -2x^5 + 8x^4 - 2x^2 + 15[/tex]

To find the end behavior, we apply the limits as x goes to infinity, in which just the term with the highest exponent is considered, hence:

[tex]\lim_{x \rightarrow -\infty} h(x) = \lim_{x \rightarrow -\infty} -2x^{5} = -2(-\infty)^5 = -2(-\infty) = \infty[/tex]

Then, as [tex]x \rightarrow -\infty, h(x) \rightarrow \infty[/tex]

[tex]\lim_{x \rightarrow \infty} h(x) = \lim_{x \rightarrow \infty} -2x^{5} = -2(\infty)^5 = -2(\infty) = -\infty[/tex]

Then, as [tex]x \rightarrow \infty, h(x) \rightarrow -\infty[/tex]

Hence, option B is correct.

Answer:

4 m = width of the rectangle.

6 m = length of the rectangle

20 m = perimeter of rectangle

3 m = side of the square

Step-by-step explanation:

Let s = length of side of square

s + 1 = width of rectangle

s + 3 = length of rectangle

Area of rectangle = (s + 1)(s + 3)

Area of square = [tex]s^{2}[/tex]

So,  (s + 1)(s + 3) + [tex]s^{2}[/tex] = 33

[tex]s^{2}[/tex] + 4s + 3 + [tex]s^{2}[/tex] = 33

2[tex]s^{2}[/tex] + 4s - 30 = 0

2([tex]s^{2}[/tex] + 2s - 15) = 0

2(s + 5)(s - 3) = 0

s = -5   or   s = 3

Length of a side cannot be negative, so -5 is ignored

3 m = side of the square

4 m = width of the rectangle

6 m = length of the rectangle

2(4) + 2(6) = 8 + 12 = 20 m = perimeter of rectangle
