Answer:

The number is 19

Step-by-step explanation:

Given : Expression "48 is 9 less than 3 times a number."

We have to find the number.

Consider the given expression "48 is 9 less than 3 times a number."

Let the number be x.

Then the expression can be written mathematically as

48 is 9 less than 3 times number x

9 less than 3 times number x = 3x - 9

then 48 = 3x - 9

adding 9 both sides, we get,

48 + 9 = 3x

57 = 3x

divide both side by 3,

we have,

x = 19

Thus, the number is 19.

Answer:

y=-2x+12

Step-by-step explanation:

This is an equation in slope-intercept form:

y=mx+b (where m is the slope and b is the y-intercept)

We are given the slope, -2.

y=-2x+b

We plug in the values (5,2):

2=(-2)*5+b

2=-10+b

b=12

The equation is:

y=-2x+12

The term "exponential growth" refers to a very rapid increase in number while the term "exponential decay" refers to a very rapid decrease in number.

<h3>Exponential growth</h3>

The "exponential" typically connotes something that happens very rapidly. Hence, it is safe to say that a suitable synonym for the word "exponential" is the word "rapid".

Hence, "exponential growth" refers to a very rapid increase in number while the term "exponential decay" refers to a very rapid decrease in number.

A random sample of 102 full-grown lobsters had a mean weight of 16 ounces and a standard deviation of 3.4 ounces. Construct a 98

pshichka [43]

Answer:

The best point estimate for a confidence interval estimating the population μ is 16 ounces.

The 98 percent confidence interval for the population mean μ is between 15.21 ounces and 16.79 ounces.

Step-by-step explanation:

We have the standard deviation for the sample, so we use the t-distribution to solve this question.

The best point estimate for a confidence interval estimating the population μ is

The sample mean, so 16 ounces.

T interval

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 102 - 1 = 101

98% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 101 degrees of freedom(y-axis) and a confidence level of $1 - \frac{1 - 0.98}{2} = 0.99$ . So we have T = 2.36

The margin of error is:

$M = T\frac{s}{\sqrt{n}} = 2.36\frac{3.4}{\sqrt{102}} = 0.79$

In which s is the standard deviation of the sample and n is the size of the sample.

The lower end of the interval is the sample mean subtracted by M. So it is 16 - 0.79 = 15.21 ounces

The upper end of the interval is the sample mean added to M. So it is 16 + 0.79 = 16.79 ounces

The 98 percent confidence interval for the population mean μ is between 15.21 ounces and 16.79 ounces.
