Answer:

138 feet

Step-by-step explanation:

plug "3" into the expression by replacing "t" with "3"

-16t^2+83t+33

-16(3)^2+83(3)+33 (remember PEMDAS)

=-16(9)+249+33

=-144+282

=138 (I hope this helps)

Answer:

1/6 of a yard

Step-by-step explanation:

Length of the board = 5/6 yard

He needs to cut the board into 5 equal sections.

Length of each section = length of the board ÷ number of sections

= 5/6 ÷ 5

= 5/6 × 1/5

= (5*1)/(6*5)

= 5/30

= 1/6

Length of each section = 1/6 of a yard

Answer:

A.

B.

C.

Mean:

Median:

Mean ≠ median, not true

D.

Answer:

B

Step-by-step explanation:

Option B is correct because from the data it's visible that all the data are around 6 miles in other words clustered. In Class A half of them are on left and half are on right. Option A is wrong because there are 17 students in class A and 18 students in class B.

Option C is wrong because the mean is 8.2 and the median is 6.

To find mean add up all the miles the students chose and divide by total students (4+4+4+4+4+5+5+5+6+6+12+13+13+13+13+14+14)/17 = 8.2

To find the median line up all the numbers and find the one in middle. It's 6.

Option D is wrong because the range for class A is (14-4)=10

and class B is (9-3)=6. So the range of class A is greater than class B.

To find range maximum value-minimum value

Answer:

C. No, because 11.34 < 12

Step-by-step explanation:

3.14 + 4.12 + 4 has to be greater than or equal to 12

solve the equation

3.14 + 4.12 + 4 >= 12

7.26 + 4 >= 12

11.26 >= 12 is false

I don't know why it says 11.34 because the numbers don't add up, so I'll assume that there is a typo somewhere.

Answer:

[tex]Mean = 0.36[/tex]

[tex]SD = 0.5817[/tex]

[tex]P(x=3) = 0.003588[/tex]

Step-by-step explanation:

Given

Let

A = Event of being a universal donor.

So:

[tex]P(A) = 0.06[/tex]

[tex]n = 6[/tex]

Solving (a): Mean and Standard deviation.

The mean is:

[tex]Mean = np[/tex]

[tex]Mean = 6 * 0.06[/tex]

[tex]Mean = 0.36[/tex]

The standard deviation is:

[tex]SD = \sqrt{np(1-p)}[/tex]

[tex]SD = \sqrt{6*0.06*(1-0.06)}[/tex]

[tex]SD = \sqrt{0.3384}[/tex]

[tex]SD = 0.5817[/tex]

Solving (b): P(x = 3)

The event is a binomial event an dthe probability is calculated as:

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

So, we have:

[tex]P(x=3) = ^6C_3 * 0.06^3 * (1-0.06)^{6-3}[/tex]

[tex]P(x=3) = ^6C_3 * 0.06^3 * (1-0.06)^3[/tex]

[tex]P(x=3) = 20 * 0.06^3 * (1-0.06)^3[/tex]

[tex]P(x=3) = 0.003588[/tex]

Answer:

3/2

Step-by-step explanation:

My reasoning is that the sum of the numbers in the left is equal to the sum of the numbers in the right.

Therefore 6=2y+3

2y=6-3

2y=3

y=1.5 or 1and a half which is equivalent to 3/2

Answer:

4y^3 + 4x^2 - 2

Step-by-step explanation:

Sort out these terms following powers of x and y:

First, y terms:

 6y^3 - 2y^3 => 4y^3

Next, constants:

 7 - 7 - 2 => -2

Next, x^2 terms:

 6x^2 - 2x^2 => 4x^2

Now write out the modified expression, using the "combined terms" results given above:

4y^3 + 4x^2 - 2

Answer:

[tex]p = 0.05[/tex]

Step-by-step explanation:

Given

See attachment for the distribution

Required

Find p

To find p, we make use of:

[tex]\sum P(x) = 1[/tex]

So, we have:

[tex]0.50 + 0.25 + 0.13 + 0.07 + p = 1[/tex]

[tex]0.95 + p = 1[/tex]

Make p the subject

[tex]p = 1 - 0.95[/tex]

[tex]p = 0.05[/tex]

What is Right triangle?

A triangle in which one of the interior angle is 90° is called a right triangle.

Given that;

Sides of a right triangle are 12, 9 and x.

Now,

By the Pythagoras theorem;

x² = 12² + 9²

x² = 144 + 81

x² = 225

x = √225

x = 15

Thus, The value of x is 15.

Answer:

5

Step-by-step explanation:

To find the median, write down all numbers in numerical order and cross off one number from each side until you are left with the middle number.

One thing to keep in mind when doing this, though, is to make sure you cross off the same amount on each side, and if you have 2 numbers left, like 13 and 14, your answer would be the number exactly between those, 13.5.

Hope this helps :)

Answer:

y < 4/3x - 2

Step-by-step explanation:

Another way to find slope is to subtract  [tex]\frac{y_{1}-y_{2} }{x_{1} -x_{2} }[/tex]. We are given two points. We can subtract the two y-values from each other for the numerator, then do the same for the x-values in the same order for the denominator.

We subtract the y-value 2 from -6.

2 - - 6 can also be taken as 2 + 6.

2 + 6 = 8.

Then, subtract the x-values.

Subtract 3 - -3, or 3 +3.

3 + 3 = 6.

Our slope, then, is [tex]\frac{8}{6}[/tex]. We can simplify this to [tex]\frac{4}{3}[/tex].

Now we can find our y-intercept. The line intersects with the y-axis at the point (0, -2)

The shading is on the left side and the line is dotted, so our sign is <.

The inequality is y < 4/3x -2.

Answer:

About 5 miles

Step-by-step explanation:

At first, I thought it would be 6 miles because 6x3 is 18 plus the initial 6 dollars which is 24. However, it says that it does not include the tip, which means that Mike DID tip the driver. So there has to be some space for the tip. If it was 6 miles it would be 24 dollars, but there is no more space for the tip. So it has to be 5 miles, because that will be 21 dollars, and assuming the tip could be about 3 dollars, then that would total up to 24 dollars.
