Bru I’m in ur class and it’s The median

Step-by-step explanation:

It’s the median

Out of all the options listed, the only one that does not show variation (spread) is the median.

The median is simply used to show the medium value of a data set. It cannot be used to tell the variation because it does not take into account all the values but rather the middle one alone.

The other options are wrong because:

In conclusion, only the median does not help with finding the variation of a dataset.

Answer: 50 ft

Step-by-step explanation:

The seagull is 20 ft above sea level.

Shark is 30 ft below seas level.

To find their distance, add their distances from sea level because it is middle ground between where they both are:

= 20 + 30

= 50 ft

The area of the triangle is:

                                         [tex]\Large\displaystyle\text{$\begin{aligned}A\triangle &= \dfrac{21+7\sqrt{15}}{2}\\ \\A\triangle &\approx 24.055\\ \\\end{aligned}$}[/tex]

You can easily find the area of a triangle using the formula:

                                         [tex]\Large\displaystyle\text{$\begin{aligned}A\triangle = \dfrac{bh}{2}\end{aligned}$}[/tex]

Where h is the height of the triangle, and b the base.

Looking at the figure we can see that h = 7, but we need to discover the base, we know that the base is:

                                               [tex]\Large\displaystyle\text{$\begin{aligned}b = 3 + x\end{aligned}$}[/tex]

Where:

                                            [tex]\Large\displaystyle\text{$\begin{aligned}8^2 &= x^2 + 7^2\\ \\x^2 &= 8^2 - 7^2 \\ \\x^2 &= 64 - 49\\ \\x^2 &= 15\\ \\x &= \sqrt{15}\end{aligned}$}[/tex]

Therefore, our base length is:

                                              [tex]\Large\displaystyle\text{$\begin{aligned}b &= 3 + x\\ \\b &= 3 + \sqrt{15}\\ \\\end{aligned}$}[/tex]

Then we can just apply the formula for the area:

                                        [tex]\Large\displaystyle\text{$\begin{aligned}A\triangle &= \dfrac{(3+\sqrt{15})\cdot 7}{2}\\ \\A\triangle &= \dfrac{21+7\sqrt{15}}{2}\\ \\A\triangle &\approx 24.055\\ \\\end{aligned}$}[/tex]

Answer:

The age of the pottery bowl is 10523 years.

Step-by-step explanation:

Amount of substance:

The amount of a substance after t years is given by the following equation:

[tex]A(t) = A(0)(1-r)^t[/tex]

In which A(0) is the initial amount and r is the decay rate.

Half-life of C14.

Researching, the half-life of c-14 is 5730 years.

This means that:

[tex]A(5730) = 0.5A(0)[/tex]

We use this to find r. So

[tex]A(t) = A(0)(1-r)^t[/tex]

[tex]0.5A(0) = A(0)(1-r)^{5730}[/tex]

[tex](1-r)^{5730} = 0.5[/tex]

[tex]\sqrt[5730]{(1-r)^{5730}} = \sqrt[5730]{0.5}[/tex]

[tex]1 - r = 0.5^{\frac{1}{5730}}[/tex]

[tex]1 - r = 0.99987903922[/tex]

So

[tex]A(t) = A(0)(0.99987903922)^t[/tex]

Age of the pottery bowl:

We have that:

[tex]A(t) = 0.28A(0)[/tex]

We have to find t. So

[tex]A(t) = A(0)(0.99987903922)^t[/tex]

[tex]0.28A(0) = A(0)(0.99987903922)^t[/tex]

[tex](0.99987903922)^t = 0.28[/tex]

[tex]\log{(0.99987903922)^t} = \log{0.28}[/tex]

[tex]t\log{0.99987903922} = \log{0.28}[/tex]

[tex]t = \frac{\log{0.28}}{\log{0.99987903922}}[/tex]

[tex]t = 10523.1[/tex]

So

The age of the pottery bowl is 10523 years.

Answer:

A)256stickers

B)8 stickers each

C)= 6 boxes

Step-by-step explanation:

THIS IS THE COMPLETE QUESTION

Mrs. Kim bought 4 boxes of stickers at the store to share with her students. Each box contained64 stickers.

Part A

Enter the total number of stickers Mrs. Kim bought at the store.

(b)

Part B

Mrs. Kim wants to share the stickers equally with each of her students. There are 32 students in her class.

Enter the number of stickers that each student will get.

8 stickers each

(c)

Part C

How many more boxes of stickers does Mrs. Kim need if she wants each of her students to get 12 stickers? Enter the number below.

more boxes of stickers

A) 4× 64 stickers= 256stickers

B,) 256stickers/ 32 students

=8 stickers each

C)if she wants each of her students to get 12 stickers?

Let the total number of stickers = X

X/32 students = 12 stickers

X= 32 ×12

= 384 stickers

Number of boxes= 384 stickers/64 stickers

= 6 boxes

Answer:

64 inches

Step-by-step explanation:

Given :

(Joe's height / Joe's shadow) = (Martha's height / Martha's shadow)

Let Martha's height = h

72 in / 108 in = h / 96 in

Cross multiply :

108 * h = 72 * 96

h = (72 * 96) / 108

h = 6912 / 108

h = 64 inches

Martha is 64 inches tall.

Answer:

They will be at the same position after 2 hours.

Step-by-step explanation:

Here, it should be asked the time it will take for Anita to catch Brad.

Anita began riding at start of the path and is riding at rate of 18 mile per hour.

This means that, after t hours, her position will be given by:

[tex]A(t) = 18t[/tex]

Brad begin from a sport 10 mile ahead of her and I riding at rate of 13 mile per hour

This means that, after t hours, his position will be given by:

[tex]B(t) = 10 + 13t[/tex]

After how much time will they be at the same position?

This is t for which:

[tex]A(t) = B(t)[/tex]

So

[tex]18t = 10 + 13t[/tex]

[tex]5t = 10[/tex]

[tex]t = \frac{10}{5}[/tex]

[tex]t = 2[/tex]

They will be at the same position after 2 hours.

Answer:

69.993

Step-by-step explanation:

Using the percentage error formula:

Percentage error = (true - measured value / true measurement ) * 100%

1% error in measurement

1% of 69.3

0.01 * 69.3 = 0.693

True measurement = error in measurement + measured value

True measurement = 0.693 + 69.3

Actual measurement = 69.993

Hence, actual measurement = 69.993.

Answer:

Bill should use 4.5 pounds of the candy costing 45 cents and 2.5 pounds of the candy costing 65 cents.

Step-by-step explanation:

With the information provided, you can say that the sum of the pounds of each type of candy is equal to 7, which can be expressed as:

x+y=7

Also, the statement indicates the 7 pound box costs $3.65 and you can say that the sum of the results of multiplying the price of each candy for the number of pounds is equal to $3.65, which is:

0.45x+0.65y=3.65

You have the following equations:

x+y=7 (1)

0.45x+0.65y=3.65 (2)

Now, you have to solve for x in (1):

x=7-y (3)

Then, you have to replace (3) in (2):

0.45(7-y)+0.65y=3.65

3.15-0.45y+0.65y=3.65

0.20y=0.50

y=0.50/0.20

y=2.5

Finally, you can replace the value of y in (3) to find x:

x=7-y

x=7-2.5

x=4.5

According to this, the answer is that Bill should use 4.5 pounds of the candy costing 45 cents and 2.5 pounds of the candy costing 65 cents.

The number of oranges in the shipment can the manager predict weighing 5 ounces will be 56. Then the correct option is B.

In parameter estimation, the expected value is an application of the weighted sum. Informally, the expected value is the simple average of a considerable number of individually determined outcomes of a randomly picked variable.

The expected value is given below.

E(x) = np

Where n is the number of samples and p is the probability.

A grocery store receives a shipment of 700 oranges. The manager randomly selects 25 oranges to weigh. In that sample, 2 oranges weigh 5 ounces.

Then the probability of the oranges that weigh 5 ounces is given as,

p = 2/25

Then the number of oranges in the shipment can the manager predicts weigh 5 ounces will be given as,

E(x) = 700 x 2 / 25

E(x) = 28 x 2

E(x) = 56

The number of oranges in the shipment can the manager predict weighing 5 ounces will be 56. Then the correct option is B.

Answer: MN = 8.5

Step-by-step explanation:

Form it into a right triangle with MN being the hypotenuse (side opposite the right angle)

To make this a right triangle, plot a point at (8,-2) and connect the sides. The lengths of the legs that form the right angle are both 6 units. Use the Pythagorean theorem to solve for length of MN. a^2+b^2=c^2. (a and b are the legs that form the right angle and c is the hypotenuse)

6^2+6^2=c^2

36+36=c^2

72= c^2

8.48528137 = c.

Question says to round to nearest tenth of a unit
