One number is 3 more than 2 times another. The sum of the numbers is 15 . Find the two numbers.

The value of the n is 64.04 after applying the tan ratio which is opposite to adjacent (TOA)

Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.

We have a right angle triangle shown in the picture.

We can use SOHCAHTOA to find the unknown length.

Using the ratio of tan which is opposite to adjacent (TOA)

tan8 = 9/n

n = 64.038 ≈ 64.04

Thus, the value of the n is 64.04 after applying the tan ratio which is opposite to adjacent (TOA)

Mean measure of central tendency is the most affected by outliers. Then the correct option is B.

The mean is the straightforward meaning of the normal of a lot of numbers. In measurements, one of the markers of focal propensity is the mean. The normal is alluded to as the number-crunching mean. It's the proportion of the number of genuine perceptions to the absolute number of perceptions.

Mean measure of central tendency is the most affected by outliers.

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 :)

The vertex of the graph moves to a point twice as far from the y-axis.

Option B is the right answer.

The general equation of a parabola is

y = a(x-h)² + k

or

x = a(y-k)² +h

where (h,k) denotes the vertex.

It is given in the question that the value of h is doubled for the equation given

y = a(x-h)² + k

if the value of the h is doubled, the vertex of the graph shifts and shifts on the x axis away from the y axis , therefore

the vertex of the graph moves to a point twice as far from the y-axis.

Option B is the right answer.

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.

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 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 :
