m_a_m_a [10]

This question belongs to greatest common factor.

49 = 7*7

56 = 7*8

So Greatest common factor = 7

Hence Susan can arrange 7 mugs on one shelf.

For 49 blue mugs, Susan can arrange 7 mugs in 7 shelves.

For 56 red mugs, Susan can arrange 7 mugs on 8 shelves.

Hence, 7 shelves are needed for BLUE mugs and 8 shelves are needed for RED mugs.

Geometry help quickly

lbvjy [14]

Answer:

RQ = 18

Step-by-step explanation:

KR is an angle bisector and divides the opposite side into segments that are proportional to the other two sides, that is

$\frac{KP}{KQ}$ = $\frac{PR}{RQ}$ , substitute values

$\frac{50}{45}$ = $\frac{38-x}{x}$ ( cross- multiply )

45(38 - x) = 50x ← distribute left side

1710 - 45x = 50x ( add 45x to both sides )

1710 = 95x ( divide both sides by 95 )

18 = x

That is RQ = 18

Write a recursive rule for the sequence. Assume it starts with the 1st term. 10, 14, 18, 21...

Papessa [141]

Option D is correct. The correct option for the recursive formula is $f(0) =6;f(n)=f(n - 1)+4$

Given the sequence 10, 14, 18...

The first term is 10, hence

a1 = 10

The previous terms will be $a_{n-1}$

From the sequence, we can see that <em>4 is being added to the previous term to get the next term</em>. Hence the nth term will be expressed as:

$a_n = a_{n-1} + 4$

Get the term before the first term $a_0$

If n = 1

$a_1 = a_{1-1} + 4\\a_1 = a_{0} + 4\\a_0=a_1-4\\a_0=10-4\\a_0=6$

Hence the correct option for the recursive formula is $f(0) =6;f(n)=f(n - 1)+4$

pickupchik [31]

Answer: Sample size would be 296.

Step-by-step explanation:

Since we have given that

Standard deviation = 4.8 hours

Margin of error = 0.65 hours

At 98% level of confidence, z = 2.33

So, It becomes,

$0.65=z\times \dfrac{\sigma}{\sqrt{n}}\\\\0.65=2.33\times \dfrac{4.8}{\sqrt{n}}\\\\\dfrac{2.33\times 4.8}{0.65}=\sqrt{n}\\\\n=(\dfrac{11.184}{0.65})^2\\\\n=17.206^2\\\\n=296.051$

Hence, sample size would be 296.
