The correct answer is C

The 5 times means we need to do 5j using multiplication, and the 4 more means we need to add 4

So the answer is 5j+4

Need help with geometric sequence quick <br> 30 points!!!!

hram777 [196]

The explicit formula for given geometric sequence is:

$a_n = 6 . 5^{n-1}$

Step-by-step explanation:

Given geometric sequence is:

6,30,150,750....

First of all we will find the common ratio.

Common ratio is the ratio between two consecutive terms of a geometric sequence

In the given sequence

a1 = 6

a2 = 30

a3 = 150

a4 = 750

Now

$r=\frac{a_2}{a_1} = \frac{30}{6} = 5\\r=\frac{a_3}{a_2} = \frac{150}{30} = 5$

The explicit formula for geometric sequence is:

$a_n = a_1 . r^{n-1}$

Putting the values of a1 and r

$a_n = 6 . 5^{n-1}$

The boy scouts are selling two types of popcorn as part of a fundraiser, butter and caramel. Butter popcorn sells for $5 per bag

Setler [38]

Answer:

Alec sold 26 bags of butter popcorn and 14 bags of caramel popcorn

Step-by-step explanation:

Let

x------> the number of bags of butter popcorn sold

y------> the number of bags of caramel popcorn sold

we know that

$x+y=40$ -----> equation A

$5x+6.5y=221$ -----> equation B

Solve the system of equations by graphing

see the attached figure

The solution is the point (26.14)

therefore

Alec sold 26 bags of butter popcorn and 14 bags of caramel popcorn

Use a t-distribution to answer this question. Assume the samples are random samples from distributions that are reasonably norma

Dimas [21]

Using the t-distribution, it is found that the proportion in a t-distribution less than −1.4 if the samples have sizes n1=30 and n2=40 is of 0.083.

<h3>How to find a proportion in a t-distribution?</h3>

The proportion is found using a calculator, with three inputs:

The tail of the test, if it is left, right, or two-tailed.

The test statistic.

The amount of degrees of freedom.

In this problem, we have a left-tailed proportion, as we want the proportion that is less than a value, with test statistic t = -1.4 and 30 + 40 - 2 = 68 df, hence the proportion is of 0.083.
