lord [1]

What it is asking is 8 times what equals 48. The best way to do this is by doing the opposite operation. 48 divided by 8 equals 6. Then if you put it in the other way you get 8(6)=48 which works out. So the answer is 6.

The distance between two cities is 87 km. What is the distance between them on a map drawn at a scale of 1:600,000?

Elena L [17]

The distance between them on a map at a scale 1 : 600,000 is 14.5 cm

Step-by-step explanation:

Scale drawing:

Is used to represent a real object with accurate sizes reduced or enlarged by a certain amount (called the scale)
States the ratio of a length in the drawing to an equivalent length in the real world
1 : 100 means 1 unit in drawing represents 100 units in real life

∵ The distance between two cities is 87 km

∵ The distance between them on a map drawn at a scale of

1 : 600,000

- That means each 1 cm represents in real life 600,000 cm, so

you must change the kilometer to centimeter

∵ 1 km = 100,000 cm

∴ 87 km = 87 × 100,000 = 8,700,000 cm

Now let us use the ratio method

→ 1 : 600,000

→ x : 8,700,000

By using cross multiplication

∴ x × 600,000 = 1 × 8,700,000

- Divide both sides by 600,000

∴ x = 14.5

∴ The distance between them on the map = 14.5 cm

The distance between them on a map at a scale 1 : 600,000 is 14.5 cm

At a large company banquet for several thousand employees and their families, many of the attendees became ill the next day. The

yan [13]

Answer:

a. Yes. This provides convincing evidence that the true proportion of all attendees who ate the fish that got sick (80%) is more than the true proportion of all attendees who did not eat the fish that got sick.

b. The mistake here would have been the rejection of the Doctor's theory or hypothesis to the effect that more attendees who ate the fish got sick than those who did not eat the fish. This is a Type 1 error. A Type 1 error occurs when a null hypothesis is rejected when it is true. On the other hand, a Type II error occurs when the null hypothesis is accepted when it should be rejected. While a Type I error is equivalent to a false positive, a Type II error is equivalent to a false negative.

Step-by-step explanation:

Total number of attendees who ordered fish = 1,000

Sample size of the attendees who ate fish = 80

Number of attendees who ate the fish and got sick = 64 (80% or 64/80)

Sample size of attendees who did not eat fish = 60

Number of attendees who did not eat fish and got sick = 39 (65% or 39/60)

The sum of three consecutive numbers is 87. What are the three numbers

sergij07 [2.7K]

Answer:

n, n+1, n+2

n+n+1+n+2= 87

3n+3 = 87

3n = 87-3

3n = 84

n = 84/3

n = 28

n+1 = 28 + 1 = 29

n+2 = 28 + 2 = 30

the three numbers are 28,29,30
