Sandy is ordering bread rolls for her party,she wants 3/5 of the rolls to be whole wheat. What other factions can represent part

Scilla [17]

Answer:

3/5 can be un-simplified into a number of different fractions. 3/5, 6/10, 12/20, etc.

The way we figure this out is by multiplying each side of the fraction by an integer. Say 2. So if the fraction is 3/4, times the top and bottom by 2 making it 6/8

podryga [215]

Step-by-step explanation:

A 2-column table with 6 rows. Column 1 is labeled x with entries 8, 12, 16, 20, 25, 28. Column 2 is labeled y with entries 2, 3, 4, 5, 6, 7.

Which equation produces the values in the table?

y = 4x

y = 4 + x

y = One-fourthx

y = 4 – x ok

According to records, the amount of precipitation in a certain city on a November day has a mean of 0.10 inches, with a standard

Andru [333]

Answer:

The probability that the mean daily precipitation will be 0.11 inches or less for a random sample of November days

P(X≤ 0.11) = 0.4404

Step-by-step explanation:

Step(i):-

Given that the mean of the Population = 0.10 inches

Given that the standard deviation of the population = 0.07inches

Let 'X' be a random variable in a normal distribution

$Z = \frac{x-mean}{S.D} = \frac{0.11-0.10}{0.07} = 0.1428$

Step(ii):-

The probability that the mean daily precipitation will be 0.11 inches or less for a random sample of November days

P(X≤ 0.11) = P(Z≤0.1428)

= 1-P(Z≥0.1428)

= 1 - ( 0.5 +A(0.1428)

= 0.5 - A(0.1428)

= 0.5 -0.0596

= 0.4404

Final answer:-

The probability that the mean daily precipitation will be 0.11 inches or less for a random sample of November days

P(X≤ 0.11) = 0.4404

Is -2, -12, -60, -120 a geometric sequence?

nlexa [21]

given,

1st term(a)= -2

2nd term (t2) =-12

3rd term (t3) =-60

4th term(t4)= -120

here common ratio (r)=t2/t1=t4/t3

or, -12/-2= -120/-60

or,6=2

hence,no -12, -60, -120 aren't in a geometric sequence because their common ratio aren't same.
