Answer:

  1/3

Step-by-step explanation:

We are given ...

  barrettes : hair ties = 5 : 7

  barrettes : hair bands = 5 : 8

Then the combined ratios are ...

  barrettes : hair ties : hair bands = 5 : 7 : 8

For every 5 barrettes, there are 7+8 = 15 hair ties and bands, so their ratio is ...

  barrettes/(hair ties and bands) = 5/15 = 1/3

Answer:\frac{1}{3}

Step-by-step explanation:

Given

There are \frac{5}{7}  as many barrettes as hair ties in Sasha's hair supplies

i.e. \frac{Barrettes}{hair ties}=\frac{5}{7}

Hair ties =Barrettes\frac{7}{5}

Also There \frac{5}{8}barrettes  as hair bands in Sasha's supplies

i.e. \frac{Barrettes}{hair bands}=\frac{5}{8}

Hair Bands=Barrettes\frac{8}{5}

Ratio of the number of Barrettes to the total number of hair ties and bands

\frac{Barrettes}{Hair band +ties}=\frac{Barrettes}{Barrettes\frac{8}{5}+Barrettes\frac{7}{5}}

=\frac{1}{\frac{8}{5}+\frac{7}{5}}=\frac{5}{8+7}

=\frac{5}{15}=\frac{1}{3}

Daniels is considering two job offers: a full-time permanent position that pays $78,000 annually and a full-time contract job th
WITCHER [35]

Answer:

Option B,contract job

Step-by-step explanation:

It is likely the number of hours in a work week is 40 hours .

With fifty weeks in year 2020 and 10 ten days of Bank Holidays,the gross annual income from the contract full time employment can be computed thus

gross annual income=$40*40*(53-2)=$81,600

The pay is $40 per hour

In a week 40 hours are worked

There are fifty three weeks in the year minus 10 days of holiday which represents 2 working weeks for a Monday to Friday job

The gross annual income for full time permanent role is $78,000

As a result,the full time contract job pays more

you are rolling a 10-sided die with sides numbered 1-10. you keep rolling the die until you roll a prime number and then stop. l
evablogger [386]

The formula for E(x) would be SUM[ X(n)P(n)] from n = 1 to n = infinity until we get the prime number

In the given problem, a 10-sided die with 1-10 numbers is rolled until we get a prime number

Prime numbers between 1-10 = 2,3,5,7 (4 prime numbers)

Non - prime numbers = 1,4,6,8,9,10( 6 non-prime number)

Let X be the number of times the die is rolled

The probability of getting a prime =

P(Prime) = \frac{4}{10}

Now, the value of

E(X)=∑x.P(x) [ x-> {1, infinity}]

= P(1)X(1) +P(2)X(2)+P(3)X(3)+P(4)X(4)........+ P(n)X(n)

= 1.\frac{4}{10} + 2. \frac{6}{10}.\frac{4}{10} + 3.\frac{6}{10}.\frac{6}{10}\frac{4}{10} + 4. \frac{6}{10}.\frac{6}{10}.\frac{6}{10}.\frac{4}{10}.......

Hence, this is the value of E(x)

Claire bought a pair of jeans that regularly cost $50 on sale for $40. What was the percent decrease in price?
Len [333]

The answer is 20%

If 50 is your 100%, take 100 and 90 for example it would be obvious that is it 10% off, so with 50 since it is half of 100 you double the 10% which will be 20%. :)
