Answer:

Step-by-step explanation:

To calculate combinations, we will use the formula nCr = n! / r! * (n - r)!, where n represents the total number of items, and r represents the number of items being chosen at a time. To calculate a combination, you will need to calculate a factorial.

The standard normal distribution is a special type of normal distribution where the mean is 0, and the standard deviation is 1. The hypothesis can not be concluded.

The standard normal distribution is a special type of normal distribution where the mean is 0, and the standard deviation is 1.

For the given problems, the Hypothesis mean is 4.5. The sample mean was 4.75 hours with a normal standard deviation of 2.0.

Now, calculating the z-score,

[tex]z = \dfrac{\bar x - \mu_o}{\dfrac{\sigma}{\sqrt n}}\\\\\\z = \dfrac{4.75-4.5}{\dfrac{2}{\sqrt{15}}}\\\\\\z = 0.48[/tex]

Now, as per the standard normal table, the p-value is 0.6844. Since the p-value is greater than the significance level, the hypothesis can not be concluded.

Hence, The hypothesis can not be concluded.

Answer:

exponential growth

Step-by-step explanation:

f(x) = 4 * 2^x

This function is in the form

y = a * b^x  where a is the initial value and b is the growth or decay rate

This is  exponential form

if b > 1 then it is growth

0< b < 1 it is decay

b =2 so it is growth

Answer:

2j + 8

Step-by-step explanation:

Given:  8 more than twice Jenny's age

Let j = Jenny's age

"twice Jenny's age" means double (multiply by 2) Jenny's age  = 2j

"more than" means to add, so "8 more than" = + 8

Therefore:

"8 more than twice Jenny's age" = 2j + 8

The age of a tree when the diameter is 11 inches is 80.

The age of the tree increases by 10 with a 1 inch increase in the diameter of the trunk. This represents a linear increase.

The equation that can be used to represent the age of a tree given its diameter is :

age of the tree when the diameter is 4 inches + [(difference between 11 inches and 4 inches) x rate of change in age)

10 + (10 x 7)  = 80

Step-by-step explanation:

Substituting into the half-life formula, we get that

[tex]N(t)=800\left(\frac{1}{2} \right)^{t/25}[/tex]

So, after 100 years,

[tex]N(100)=800\left(\frac{1}{2} \right)^{100/25}=\boxed{50 \text{ mg}}[/tex]

The graph of the given linear equation is the one that you can see below.

To graph lines, we need to get two points on the line. To get the points, we can evaluate the line in two different values of x. Here I will use x = 1 and x = 0.

For x = 0 we have:

y = 15 - 4*0 = 15

So we have the point (0, 15).

For x = 1 we have the point:

y = 15 - 4*1 = 11

So we have the point (1, 11).

Now we need to graph these two points and connect them with a line, you will get the graph that you can see below.

Answer:

18 inches

Step-by-step explanation:

Equation is (2x-32)(x)=72, where x represents length and (2x-32) represents the width. When you simplify the equation, it ends up as 2x^2-32x-72=0. After factoring, you get 2(x-18)(x+2). Since x cannot be negative, it would therefore be 18. If you plug it back into the equation, you can see that it is right :)

What is probability?

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

Here, we  have,

Given :

Total T-shirts =4

He chose T-shirt to take on weekend trip = 2

In an random trial or experiment , the set of all possible outcomes or results of that experiment is called the sample space of it.

If the t-shirts are labeled A, B, C, and D,

then its sample space of the event is given by

S= {AB, AC, AD, BC, BD, CD}

Hence, The solution is: C is the right answer. Sample space of the given event is given by S= {AB, AC, AD, BC, BD, CD}
