Answer:

  • A = 90°, C = 40°
  • A = 40°, C = 90°

Step-by-step explanation:

In a right triangle one angle is 90° and the other angle is the complement of the acute angle given.

Angles A and C are not specified, but we know the other two angles are 40° and 90°. The values can be assigned two ways:

  A = 90°, C = 40°

  A = 40°, C = 90°

there are only red counters and blue counters in a bag. Jim takes at random a counter from a bag. the probability that the count
KengaRu [80]

Answer:

0.495 probability that Jim and Molly take counters of different colours

Step-by-step explanation:

For each trial, there are only two possible outcomes. Either a blue counter is picked, or a red counter is picked. The counter is put back in the bag after it is taken, which means that we can use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

In which C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

And p is the probability of X happening.

The probability that the counter is red is 0.45

This means that p = 0.45

Jim taken a counter, then Molly:

Two trials, so n = 2

What is the probability that Jim and Molly take counters of different colours?

One red and one blue. So this is P(X = 1).

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 1) = C_{2,1}.(0.45)^{1}.(0.55)^{1} = 0.495

0.495 probability that Jim and Molly take counters of different colours

Without drawing a graph find the intercepts of each line. y+5=–2x
Lostsunrise [7]

Answer:

see explanation

Step-by-step explanation:

The intercepts are where the line crosses the x and y axes.

To find the x- intercept ( where the line crosses the x- axis) let y = 0 in the equation and solve for x, that is

0 + 5 = - 2x

5 = - 2x ( divide both sides by - 2 )

x = - \frac{5}{2} = - 2.5 ← x- intercept ⇒ (- 2.5, 0 )

To find the y- intercept ( where the line crosses the y- axis ) let x = 0 in the equation and solve for y, that is

y + 5 = 0 ⇒ y = - 5 ← y- intercept ⇒ (0, - 5 )

Suppose an experiment consists of randomly drawing a marble out of a bag and replacing the marble. the bag contains 3 yellow mar
Savatey [412]
Hi there!

Since the yellow marbles to the radio of total marbles is 3/15,

3/15 = 5

We need to divide the total amount is times the marble is drawn by the ratio.

20 ÷ 5 = 4

So, the yellow marble would be drawn 4 times.

Hope this helps!
