547% of what number is 366.49

Rom4ik [11]

Answer:

Step-by-step explanation:

To solve this question ( that is to know the number), we must interpret the statement mathematically. Let the unknown number be T then,

547% of T = 366.49

547 * T/100 = 366.49

547T = 36646

T = 36649/547

= 67

It means that 547% of 67 gives 366.49

A retail shop accepts only cash or checks suppose that 45% of its customers carry cash 44% carry checks and 31% carry both cash

sergejj [24]

Answer:

Step-by-step explanation:

The number of customers carrying cash=45% = 0.45

The number of customers carrying checks= 44% =0.44

The number of customers carrying both = 31% = 0.31

So,

To find the probability we will write the expression:

cash+checks-cash or checks(both)=cash and checks

0.45+0.44-both=0.31

0.45+0.44-0.31=both

0.58=both....

Chapter 8 Written Homework 1. A hypothesis test is conducted to test the claim that the proportion of people with dark hair at M

UNO [17]

Answer:

we reject H₀

Step-by-step explanation: Se annex

The test is one tail-test (greater than)

Using α = 0,05 (critical value ) from z- table we get

z(c) = 1,64

And Test hypothesis is:

H₀ Null hypothesis μ = μ₀

Hₐ Alternate hypothesis μ > μ₀

Which we need to compare with z(s) = 2,19 (from problem statement)

The annex shows z(c), z(s), rejection and acceptance regions, and as we can see z(s) > z(c) and it is in the rejection region

So base on our drawing we will reject H₀

Ivy's basketball team scored 38 point in the first game of the season. In the next 2 games they scored a total of 77 points. For

AleksAgata [21]

Answer:

The expression given by Ivy is WRONG.

The correct expression is $(19 + 77 x (0.5) )

The total mount in jar = $57.5

Step-by-step explanation:

Here, for each point scored, $0.5 is put in the jar.

Now, the point scored in the first game = 38 points

So, the amount put in the jar for 38 points = 38 x ( amount for 1 point)

= 38 x ( $0.5) = $19

So, after first game, jar has $19.

Now, the point scored in the(2 +3) game = 77 points

So, the amount put in the jar for 77 points = 77 x ( amount for 1 point)

= 77 x ( $0.5) = 77 x (0.5)

So, after second and third game, jar has $ (77 x (0.5)).

Now, total amount in jar

= Amount after first game + Amount after second and third game

= 19 + 77 x (0.5)

But , here THE TOTAL AMOUNT given by Ivy = 38+(77 x 0.5)

And 19 + 77 x (0.5) ≠ 38+(77 x 0.5)

Hence, the expression given by Ivy is WRONG.

The correct expression is $(19 + 77 x (0.5) )

And, the total mount in jar = 19 + 38.5 = $57.5
