[ Answer ]

$\boxed{37}$

[ Explanation ]

The Median Is The Number That Separates Top Half Of The Number Set From The Bottom

Ex: 1, 1, 2, 5, 6, 6, 9

Median - 5

Explanation: 5 is the number in the exact middle that is separating the bottom half of the number set (1, 1, 2) from the top half of the number set (6, 6, 9).

Ex: 1, 1, 2, 6, 6, 9

Median - 4

Explanation: 4 is the mean of 2 and 6. (Mean = Sum / Numbers you are adding up)

===========================

22, 37, 49, 15, 72

Order numbers from least to greatest:

15, 22, 37, 49, 72

37 is the mean because it is in the exact middle and separates 15 and 22 from 49 and 72.

Answer:37

Step-by-step explanation:

first you put them in order from least to greatest

which would be 15,22,37,49,72

then the middle number would be your answer hope this helps!

A botanist wants to determine if a fertilizer is effective

Maru [420]

Based on the information provided, the statement which is a valid conclusion is only: option A.

<h3>What is a valid conclusion?</h3>

A valid conclusion can be defined as a statement that is essentially based on empirical data, formulated hypotheses, facts, and prudent experimental design, which entails that relationship between data variables are reasonable, credible and valid.

Based on the information provided, the statement which is a valid conclusion is that the botanist can make inferences for all plants, and he can draw his conclusion that the fertilizer would help all plants grow taller.

What is the value of f(-4)?

Ghella [55]

Given is a piecewise function which follows different expressions according the the value of input x.

Given $f(x)=\left \{ {{-10, \;if \;x2} } \right.$

It says to find f(-4) i.e. the value of function f(x) at x = -4.

At point x = -4, f(x) is x³, if -5 ≤ x ≤ 2.

So, f(-4) = (-4)³

f(-4) = -4 × -4 × -4

f(-4) = -64.

Hence, option A is correct i.e. -64.

Verify that the following function is a probability mass function, and determine the requested probabilities. f left-parenthesis

Licemer1 [7]

Answer:

$f(x) = \frac{27}{13} (\frac{1}{3})^x , x=1,2,3$

1) $f(x_i) \geq 0, \forall x_i$

2) $sum_{i=1}^n P(X_i) =1$

We can find the individual probabilities and we got:

$f(1)= \frac{27}{13} (\frac{1}{3})^1 =0.6923$

$f(2)= \frac{27}{13} (\frac{1}{3})^2 =0.2307$

$f(3)= \frac{27}{13} (\frac{1}{3})^3 =0.0770$

And the sum of the 3 values 0.6923+0.2307+0.0770= 1 so then we satisfy all the conditions and we can conclude that f(x) is a probability distribution.

$P(X \leq 1) = P(X=1) =0.6923$

$P(X>1) = P(X=2) +P(X=3) = 0.2307+0.0770=0.3077$

$P(2$

Step-by-step explanation:

For this case we have the following density function:

$f(x) = \frac{27}{13} (\frac{1}{3})^x , x=1,2,3$

In order to satisfty that this function is a probability mass function we need to check two conditions:

1) $f(x_i) \geq 0, \forall x_i$

2) $sum_{i=1}^n P(X_i) =1$

We can find the individual probabilities and we got:

$f(1)= \frac{27}{13} (\frac{1}{3})^1 =0.6923$

$f(2)= \frac{27}{13} (\frac{1}{3})^2 =0.2307$

$f(3)= \frac{27}{13} (\frac{1}{3})^3 =0.0770$

And the sum of the 3 values 0.6923+0.2307+0.0770= 1 so then we satisfy all the conditions and we can conclude that f(x) is a probability distribution.

And if we want to find the following probabilities:

$P(X \leq 1) = P(X=1) =0.6923$

$P(X>1) = P(X=2) +P(X=3) = 0.2307+0.0770=0.3077$

$P(2$

A student has a test scores of 87, 89, 94 points. What must he score on the fourth exam to have an average of at least 92 points

larisa86 [58]

Answer: He must have atleast 98 points on the next exam in order to get an average of 92 points.

Step-by-step explanation: To calculate average, you need to add all the numbers given, and divide the sum by how many numbers there are. 87 + 89 + 94 + 98 (equals 368), and divide 368 by 4. You will get the average of 92 as its result.
