Answer:

Step-by-step explanation:

1. There will be 9 roses in total.

Probability Orange: 2/9

Probability Yellow: 3/9 = ⅓

Probability Pink: 4/9

2. 4/7 as there are 7 bowls in total and 4 are chocolate.

3. 4/10 = ⅖ (simplified) There are 10 fruits in total and 4 are apples.

4. 5/15 = ⅓ (simplified) There are 15 cars in total and 5 or them are cooper minis.

5. 2/6 = ⅓ (simplified) There are 6 textbooks and 2 of them are math.

6. 13/20 There are 20 drinks and 13 of them are lemonade.

7. There are 10 toys in total.

Probability toy cars: 3/10

Probability dolls: 2/10 = ⅕ (simplified)

Probability balls: 5/10 = ½ (simplified)

8. In total the number of red roses and lilies are 7. There are 10 flowers in total so the number of jasmines are 3. Therefore the probability of getting a jasmine is 3/10

9. 20/50 = ⅖ (simplified) There are 50 papers in total and 20 of them are yellow.

10. 8/18 = 4/9 (simplified) There are 18 buses and 8 of them are air conditioned.

Rhonda bought five shirts from a

densk [106]

Answer:

Option C $10+5x=24+3x$

Step-by-step explanation:

Let

x ------> the cost of each shirt

we know that

The cost of 5 shirts plus $10 (amount of money that would remain) must be equal to the cost of 3 shirts plus $24 (amount of money that would remain). Considering that the cost of the shirts is the same

The linear equation that represent this scenario is

$10+5x=24+3x$

Solve for x

$5x-3x=24-10$

$2x=14$

$x=\$7$

Last year, 50% of MNM. Inc. employees were female. It is believed that there has been a reduction in the percentage of females i

Serhud [2]

Answer:

We conclude that there has been a significant reduction in the proportion of females.

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 400

p = 50% = 0.5

Alpha, α = 0.05

Number of women, x = 118

First, we design the null and the alternate hypothesis

$H_{0}: p = 0.50\\H_A: p < 0.50$

This is a one-tailed test.

Formula:

$\hat{p} = \dfrac{x}{n} = \dfrac{118}{400} = 0.45$

$z = \dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}$

Putting the values, we get,

$z = \displaystyle\frac{0.45-0.50}{\sqrt{\frac{0.50(1-0.50)}{400}}} = -2$

Now, we calculate the critical value.

Now, $z_{critical} \text{ at 0.05 level of significance } = -1.645$

Since the calculated z-statistic is less than the critical value, we fail to accept the null hypothesis and reject it. We accept the alternate hypothesis.

Thus, there has been a significant reduction in the proportion of females.
