Change 3 to 5 in exercise 4

Five times the sum of some number plus 3 is equal to 7 times the number minus 1.

5(x+3)=7x-3 which is the equation, then we solve for it, and the answer is 9

What is the maximum value that a marginal relative frequency can be? Explain.

mart [117]

The maximum value it can be would be 100%. The only times that it could be this high is when there is only a class on the frequency distribution table. Another way, is that there is only one column variable on the table (& or if there is only one row.) Any other time is will be less, but the maximum stays 100%.

Can someone please show me the steps in finding the answers to these two problems ?

ratelena [41]

Answer:

y = 8^(x-1)
x = 24

Step-by-step explanation:

The first step is always to look at the question to see what you are given and what you are asked for. The next step is to identify the relevant relations between what you have and what you need to find.

__

1) You are given a sequence of (x, y) points where x increases by 1 from one point to the next, and y increases by a factor of 8. This tells you the value of y form a geometric sequence that is described by an exponential function.

The general form of the n-th term of a geometric sequence is ...

an = a1·r^(n-1)

where a1 is the value for n=1, and r is the common ratio.

If this were a geometric sequence, we could write the general term using a1=1 and r=8:

an = 1·8^(n-1)

Instead, this is a relation between x and y. It is the same relation as for the geometric sequence, but with different variable names. We have y instead of an, and we have x instead of n. So, the equation is ...

y = 8^(x -1) . . . . . . . or . . y = (1/8)8^x

__

2) This equation is of the form ...

k·∛x = 6

Since k is also a cube root, it is easiest to cube both sides of the equation:

9x = 6³ = 216

Now, you can divide by 9 to find x:

x = 216/9

x = 24

Can anyone find the answers this for these question but make them fractions

k0ka [10]

We are given fractions $\frac{77672}{5548}$ and $\frac{288184}{34}$ .

In order to write them in simplest fractions, we need to find a common number that can divide both top and bottom.

Let us work on simplifying first fraction first.

$\frac{77672}{5548}$

We have 77672 on the top and 5548 in the bottom.

The greatest number 5548 can divide both 77672 and 5548 both.

Dividing 77672 by 5548, we get 14 and dividing 5548 by 5548 we get 1.

Putting quotent 14 on the top and 1 in the bottom, we get

$\frac{14}{1}$ . This is the answer for first part.

Let us work on simplifying second fraction $\frac{288184}{34}$ .

Top number 288184 and bottom number 34, both can be divided by 34.

On dividing 288184 by 34, we get 8476 and dividing 34 by 34, we get 1.

Putting quotent 8476 on the top and 1 in the bottom, we get

$\frac{8476}{1}$ . This is the answer for second part.

Almonds cost $3.49 per pound a bag of almonds cost $6.95 to the nearest whole pound about how many pounds of almonds are in the

Kryger [21]

Answer:

The hint in this problem is the word "about" or approximately how many pounds. So we could find the solution by estimation through rounding off. We know that almonds cost about 3.50 per pound and a bag costs about $7.00. Dividing 7 by 3.50 per pound, will give us $7 ÷ $3.50 = 2 pounds.

The answer is 2 pounds.
