1 2/5 divided by 2 3/4

Mathematics
1 answer:
LekaFEV [45]3 years ago
5 0

The answer is 28/55.

In order to find this, the easiest thing to do is to make both of the terms improper fractions. To do that for any term, you need to multiply the big number by the bottom of the fraction (denominator) and then add that to the top number (numerator). Then this can be expressed over the original bottom number.

\frac{WHOLE*BOTTOM + TOP}{BOTTOM}

\frac{1*5 + 2}{5}

\frac{7}{5}

Now do the same for the second fraction.

\frac{WHOLE*BOTTOM + TOP}{BOTTOM}

\frac{2*4 + 3}{4}

\frac{11}{3}

Now that we have both in that way, we can flip the second fraction and multiply. This is the same as dividing when you are using fractions.

\frac{7}{5} / \frac{11}{4}

\frac{7}{5} * \frac{4}{11}

\frac{28}{55}

Given the two functions, which statement is true?<br> fx = 3^4, g(x) = 3^x + 5
Neko [114]

Answer:

third option

Step-by-step explanation:

Given f(x) then f(x) + c represents a vertical translation of f(x)

• If c > 0 then shift up by c units

• If c < 0 then shift down by c units

Given

g(x) = 3^{x} + 5 ← this represents a shift up of 5 units

Thus g(x) is the graph of f(x) translated up by 5 units

The manager of a large company that sells pet supplies online wants to increase sales by encouraging repeat purchases. The manag
MA_775_DIABLO [31]

Answer:

There is not a convincing statistical evidence, at the significance level of a = 0.05, that the manager's belief is correct.

As the null hypothesis maybe false accepting it makes a type II error.

Step-by-step explanation:

Let the null and alternate hypotheses be

H0: p ≤ 0.4  vs Ha : p>0.4

q= 1-p= 1-0.4= 0.6

The significance level alpha is 0.05

The critical region for one tailed test is Z> ± 1.645

The sample proportion is p^= x/n= 38/90=0.42222

Using the z statistic

z= p^- p/ √pq

z= 0.422-0.4/ √0.4*0.6

z= 0.04536

Since the calculated value of z= 0.04536 does not lie in the critical region  Z> ± 1.645 we fail to reject null hypothesis.

There is not sufficient evidence to support the manager's claim.

Type I error is when we reject the true null hypothesis .

Type II error is when we accept the false null hypothesis .

As the null hypothesis maybe false accepting it makes a type II error.

Disk requests come in to the disk driver for cylinders 10, 22, 20, 2, 40, 6, and 38, in that order. A seek takes 6 msec per cyli
marta [7]

Answer:

Step-by-step explanation:

The order for FCFS is: 20->10->22->20->2->40->6->38.

Distance is

10+12+2+18+38+34+32 = 146

cylinders, so time is

146* 6 = 876 sec.

The order for elevator is:

20->20->22->38->40->10->6->2.

Distance is

0+2+16+2+30+4+4 = 58

cylinders, so time is

58 * 6 =348 msec.

The order for CCN is:

20->20->22->10->6->2->38->40.

Distance is

0+2+12+4+4+36+2 = 60

cylinders, so time is 60 * 6 =360 msec.

10)
200 / 5 = 40

answer
p >= 40

11)
$15 per hour
so
15p >= 200
solve for p

p >= 200/15
p >= 13.33 or p?= 13 1/3

minimum hours = 13.33 or 13 1/3
