ANSWER

45 green bands

EXPLANATION

The ratio of red hair bands to green hair bands is

5 : 9

The total ratio is:

$9 + 5 = 14$

If there are a total of 70 hair bands,

Then the number of green bands

$= \frac{9}{14} \times 70$

Simplify

$= 9 \times 5$

Multiply

$= 45$

Therefore, there are 45 green bands.

ALGREBRA - 4 PARTS

xenn [34]

Answer:

Estimate of population 0.61

(b) Margin of error = 0.07 The real population interval estimation is ± 7%.

c). Margin of error = 0.15

d) The real population's interval estimation is ± 15%

e). Yes, the action argument of the group is based on a half-range estimation of the true population. The reason that 62% ± 15% = 47%, or 77%, while 47% is similar to 45%, as the Collective action group states.

Arada [10]

This shape would be a rectangular prism, with 4 rectangular sides, and 2 square or smaller rectangular sides.

An example of a rectangular prism would be a brick. It has 4 sides that are perfectly alike, then two other sides that are like each other.

If sin ZA = { and cos ZA = }, what is tan ZA?

Ainat [17]

Answer:

A: 3/4

Step-by-step explanation:

sine is the length of the opposite side / length the hypotenuse side

cosine is the length of the adjacent side / length the hypotenuse side

using what's given:

the opposite side has a length of 3
the adjacent side has a length of 4
the hypotenuse side has a length of 5

Tangent is the ratio between the opposite side length and the adjacent side length (opp/adj). With our givens, this means tan(A) = 3/4. See image for more.
