HELP, I’ll give the brainliest answer if correct

Mathematics
1 answer:
DochEvi [55]3 years ago
4 0

Answer:

Answer is 5,770 miles.

Step-by-step explanation:

okay we know ED = 240 miles

we know EC = ED + DC

EC = 240 + 3960

EC = 4200

we know in a right angled triangle, hypotenuse square is the sum of square of sides

EC^2 + CH^2 = EH^2

EH^2 = 4200^2 + 3960^2

EH^2 = 17,640,000 + 15,681,600

EH^2 = 33,321,600

EH = Root 33,321,600

EH = 5772.48

If we round to the nearest ten,

EH = 5770

A large study of German children of Caucasian descent found that 46% have brown hair and that 25% have freckles. Nonetheless, yo
STatiana [176]

Answer:

Having brown hair and having freckles are not necessarily independent events          

Step-by-step explanation:

We are given the following information in the question:

Percentage of children having brown hairs = 46%

Percentage of people children having freckles = 25%

But it cannot be concluded that

German children of Caucasian descent are brown‑haired with freckles =

0.46\times 0.25 = 0.115 = 11.5\%

This is not always true because of the following reasons:

Brown hair and having freckles are not necessarily independent events.

We can not assume that event of a child having brown hair is independent of the event of child having freckles. The events could be dependent as well.

The above will only be true when event of a child having brown hair is independent of the event of child having freckles.

If the events are independent then,

P(A \cap B) = P(A)\times P(B)

A veterinarian estimated the weight of a puppy to be 7 kg. The actual weight of the puppy was 6.6 kg.
KIM [24]

9514 1404 393

Answer:

  • absolute error: 0.4 kg
  • relative error: 6.1%

Step-by-step explanation:

The absolute error is the difference between the estimate and the actual weight:

  7.0 kg -6.6 kg = 0.4 kg . . . . absolute error

__

The relative error is the ratio of the absolute error to the actual weight:

  (0.4 kg)/(6.6 kg) × 100% = 6.060606...% ≈ 6.1% . . . . relative error

Cindy pics six times as many apples as Mary John pick eight times as many apples as Mary together they picked 135 apples how man
spin [16.1K]

Answer:

126 apples

Step-by-step explanation:

Let the number of apples picked by Mary=m

Cindy picks 6 times as many as Mary= 6Xm=6m

John picks 8 times as many as Mary= 8Xm=8m

Altogether they picked a total of 135 apples.

m+6m+8m=135

15m=135

m=135/15

m=9

We want to determine how many apples John and Cindy Picked.

John Picked 6m apples

Cindy Picked 8m apples

Their combined total= 6m+8m =14m

Since m=9

14m =14 X9 =126 apples

John and Cindy picked a total of 126 apples
