A spinner has equal regions numbered 1 through 20. What is the probability that the spinner will stop on an odd number or a mult

klio [65]

Answer:

Probability that the spinner will stop on an odd number or a multiple of 5 is 0.6

Step-by-step explanation:

Probability = $\frac{Required outcomes}{Total possible outcomes}$

We are given the equal regions numbered from 1 through 20 which means that our total possible outcomes are 20

Total possible outcomes: 20

Outcomes that spinner will stop on an odd number, n(Odd): 10

1, 3, 5, 7, 9, 11, 13, 15, 17, 19

Probability of spinner stoping on Odd number:

P(Odd) = $\frac{n(Odd)}{Total}$ = $\frac{10}{20}$ = $\frac{1}{2}$ = 0.5

Outcomes that spinner will stop on a multiple of 5, n(5): 4

5, 10, 15, 20

Probability of spinner stoping on multiple of 5:

P(5) = $\frac{n(5)}{Total}$ = $\frac{4}{20}$ = $\frac{1}{5}$ = 0.2

Odd numbers which are a multiple of 5 are: 5 and 15

So,

P(Odd and 5) = $\frac{2}{20}=\frac{1}{10}=0.1$

Thus Probability of spinner stopping at odd number or a multiple of 5 becomes:

P(Odd or 5) = P(Odd) + P(5) - P(Odd and 5) = 0.5 + 0.2 - 0.1 = 0.6

Robert accepted a new job at a company with a contract guaranteeing annual raises. Let S represent Robert's salary after working

vesna_86 [32]

Answer:

74,000

Step-by-step explanation:

In the year where he got 104,000 the year before he got 6,000 less. The year before 98,000 he got 12,000 less which means that now it would just be 86,000-12,000=74,000

I think this is right but you can double check on a calculator

Hope this helped!

In triangle ABC, point D is the centroid, and BD = 6. Find BE.

pshichka [43]

Given:

In triangle ABC, point D is the centroid, and BD = 6.

To find:

The measure of side BE.

Solution:

We know that the centroid divides each median in 2:1.

In the given figure BE is a median and point D is the centroid. It means point D divides the segment BE in 2:1.

Let BD and DE are 2x and x respectively.

We have, BD = 6 units.

$2x=6$

$x=\dfrac{6}{2}$

$x=3$

Now,

$BE=BD+DE$

$BE=6+x$

$BE=6+3$

$BE=9$

Therefore, the measure of side BE is 9 units.

I have no idea what to do I missed an entire lesson while I was in the hospital. Help please. I need to show my work as well.

Vlada [557]

Answer:

Step-by-step explanation:

$\sqrt[3]{\frac{n}{4} } +\frac{n}{10} \\\\\sqrt[3]{\frac{500}{4} } +\frac{500}{10}\\\\\sqrt[3]{125} +50\\5+50\\55$

A salesperson is paid a weekly salary of $1000, plus a commission of 5% of all her sales for the week.

garri49 [273]

Answer:

A) Total weekly salary = $1000 + ( 0.05 × s )

B) Yes this is a function

C) This is a function because the weekly salary is dependent on the number of sales 's'. Hence, total weekly salary is a function of sales.

D) Domain will be [ 0, ∞ ]

Step-by-step explanation:

Given :

Weekly salary = $1000

Commission = 5% of all her sales

Let the number of sales be 's'

thus,

A) Total weekly salary = $1000 + ( 0.05 × s )

B) Yes this is a function

C) This is a function because the weekly salary is dependent on the number of sales 's'. Hence, total weekly salary is a function of sales.

D) The domain here will be all the possible values of sales i.e 's'

Hence,

sales will always be positive

thus,

domain will be [ 0, ∞ ]
