Answer:

I hope i answered it correctly if not try Mayway again thats what i used

Step-by-step explanation:

Total probability equals 1.

Subtract the probability of blue from 1:

1-0.4 = 0.6

Red and yellow total is 0.6

Since they have the same number of cubes, the probability of both would be the same so divide the remainder by 2:

0.6 /2 = 0.3

The probability of red is 0.3

The probability of yellow is 0.3

30 blue cubes with a probability of 0.4.

Let total cubes = x

30 blue/ x = 0.4

Multiply both sides by x:

30 = 0.4x

Divide both sides by 0.4

X = 30/0.4

X = 75

Total cubes is 75

This doesn’t make sense though because red and yellow are supposed to be the same and if you subtract blue from total it’s an odd number so red and yellow aren’t the same:

75-30 = 45

45/2 = 22.5

A brainliest will be appreciated.

Answer:

C. 4k - 3.

Step-by-step explanation:

(7 - 3k) - (4 - 5k) - (6 - 2k)

Distributing the negative over the last 2 parentheses:

= 7 - 3k - 4 + 5k - 6 + 2k

=  -3k + 5k + 2k + 7 - 4 - 6

= 4k -3.

Step-by-step explanation:

Answer:

221.0 m

Step-by-step explanation:

First, find x using trigonometric ratio formula:

Reference angle = angle of depression = angle of elevation = 64°

Opposite side length = 142 m

Adjacent side length = x

Thus:

tan(64) = 142/x

x*tan(64) = 142

x = 142/tan(64)

x = 69.3 (nearest tenth)

Next, find distance from top of the hill to the buoy using Pythagorean Theorem.

Let the distance be y.

We would have:

y² = 142² + (69.3 + 100)²

y² = 20,164 + 28,662.49

y² = 48,826.49

y = √48,826.49

y = 221.0 m (nearest tenth)

Answer:

In many instances, the lyrics to folk songs came from existing nursery rhymes or poems, and some of the nursery rhymes had variations, depending on region or time. Thus, these folk songs may have lyrics that are slightly different from those you are familiar with.

Therefore, in my opinion, I think that Nursery songs can be considered folk music.

Answer:

$39

Step-by-step explanation:

First, let's get the values of each number by rounding them off to the nearest dollar before adding them.

1. $2.69 = $3

2. $14.45 = $14

3. $8.05 = $8

4. $13.95 = $14

Now that you have the rounded off numbers, you may add them.

Let's solve.

The estimated total is $39.

Answer:

slope = - 8

Step-by-step explanation:

pass (0,6) (1,-2)

slope: (-2 - 6) / (1 - 0) = - 8

Answer:

we will fail to reject the null hypothesis and conclude that there's insufficient evidence to support the claim that the percentage is actually more than the reported percentage

Step-by-step explanation:

We are given;

Population proportion; p = 30% = 0.3

Sample proportion; p^ = 37% = 0.37

Sample size; n = 100

Let's define the hypotheses;

Null hypothesis; H0: p ≤ 0.3

Alternative hypothesis; Ha: p > 0.3

Formula for the test statistic is;

z = (p^ - p)/√(p(1 - p)/n)

Thus;

z = (0.37 - 0.3)/√(0.3(1 - 0.3)/100)

z = 0.07/0.04582575695

z = 1.53

From z-distribution table, at z=1.53 we have;

p-value = 1 - 0.9370 = 0.063

This p-value is greater than the significance level of 0.02 and thus we will fail to reject the null hypothesis and conclude that there's insufficient evidence to support the claim that the percentage is actually more than the reported percentage

Answer:

29

Step-by-step explanation:

If x = 4, then y = 4x + 13 can be written as the following:

y = 4(4) + 13

y = 16 + 13

y = 29

Answer:

Garth didn't save in the bank or buy raffle tickets

Step-by-step explanation:

Garth earns $9.32 per hour. One week, he works 16 hours, thus his earnings that week were 16*$9.32=$149.12.

The question specifies Garth deposits $150 in a bank and decides to use the rest to buy raffle tickets, but he didn't earn enough money to save that much.

This problem cannot continue since the earnings are not enough to save or buy anything.

Answer: Garth didn't save in the bank or buy raffle tickets

Answer:

The probability is 0.16602

Step-by-step explanation:

We start by calculating the z-score

We have this mathematically as;

z-score = (x-mean)/SD/√n

From the question,

we have x = 6.15

mean = 6.06 hours

standard deviation = 0.55 hours

n = 35

Substituting these values, we have

z-score = (6.15-6.06)/0.55/√35

z-score = 0.09/0.55/5.92

z-score = 0.97

So the probability we want to calculate is:

P ( z > 0.97)

we make use of the standard normal distribution table here

The value is; 0.16602

C = 0.475

Step-by-step explanation:

you divide 5.70 by 12 and get that one bagel costs 0.475 cents. hope this helps!

c=40 is the answer

6x55=330 cents

$570-570 cents (570-330)÷(12-)

=40 cents

Thus, c=40

The unitary method is a method for solving a problem by first finding the value of a single unit and then multiplying the value of a single unit to find the required value.

The unitary method is a procedure that calculates the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.

Simply put, the unitary method is used to find the value of a single unit from a given plural. For example, if the price of 40 pens is 400 rupees, the price of one pen would be: This can be done using a uniform method
