What is one and two thirds divided by four fifths

Mathematics
2 answers:
Alja [10]3 years ago

Answer: 25/12

Step-by-step explanation: One and two thirds is equal to 5/3, so now all you have to do is divide 5/3 by 4/5. To divide fractions you multiply the first fraction to the reciprocal of the second fraction. The reciprocal simply means to switch the numerator with the denominator. Multiply 5/3 by 5/4. To multiply fractions you need to multiply straight across. 5 times 5 is 25 and 3 times 4 is 12, so the answer is 25/12.

First, remove parenthesis.

7i4i

Secondly, multiple by the numbers.

7*4=28

-28ii

Third, apply exponents rule.

-28i^2

i^2=-1

-28(-1)

Finally, refine.

=28\\

Given that X ~ N(120, 35). We survey samples of 25 and are interested in the distribution of X-bar. Find the z-score associated
lubasha [3.4K]

Answer:

Option c -2.8571

Step-by-step explanation:

z-score are calculated as

z=\frac{xbar-mean}{\frac{S.D}{\sqrt{n} } }.

We are given that mean=120 and standard deviation=S.D=35 as X~N(120,35).

Sample size=n=25.

We have to find z-score for x-bar=100. So,

z-score=[100-120]/[35/√25]

z-score=[-20]/[35/5]

z-score=-20/7

z-score=-2.8571.

Thus,  the z-score associated with x-bar = 100 is -2.8571.

What is the slope-intercept form for<br> y – 6 = 3 ( x− 1/3 )
Leviafan [203]

Answer:

y=3x+5

Step-by-step explanation:

This is th eanswer because slope intercept form is always y=mx+b.

So, if you simplify the right side of the equation, you then get

y-6=3x-1, I got that because 3 multiplied by -1/3, you get -1.

Then you add 6 to both sides to isolate y by itself. So, now you have

y=3x+5.

Hope this is helpful
