Answer:

8 plantains

Step-by-step explanation:

Cost and number of plantains are in proportion

Number of plantains that can be bought for $ 4 be 'x'

48 : 24 :: x : 4

Product of means = product of extremes

24 * x = 48*4

$x = \frac{48*4}{24}$

x = 2 * 4

x = 8

Answer:

The answer is "294.2075".

Step-by-step explanation:

Given:

$\hat{p} = 0.5 \\\\1 - \hat{p} = 1 - 0.5 = 0.5\\\\E = 4\% = 0.04\\\\$

At $83\%$ confidence level the z is ,

$\alpha = 1 - 83\% = 1 - 0.83 = 0.17\\\\\frac{\alpha}{2} = \frac{0.17}{2} = 0.085\\\\Z_{\frac{\alpha}{2}} = Z_{0.085} = 1.3722\\\\n = (\frac{Z_{\frac{\alpha}{2}}}{E})^2 \times \hat{p} \times (1 - \hat{p})\\\\$

$= (\frac{1.3722}{0.04})^2 \times 0.5 \times 0.5\\\\= (34.305)^2 \times 0.5 \times 0.5\\\\= 1,176.83 \times 0.5 \times 0.5\\\\= 1,176.83 \times 0.25\\\\=294.2075$

Mrs. Ellington has a $50 gift card to Best Buy. She purchased a DVD for $28. Which inequality shows all possible values for x, t

Effectus [21]

Answer:

4th option

Step-by-step explanation:

She purchased a DVD for $28.

$50 - $28 = $22

1. 22 < 22

2. 22 > 22

3. 22 < 78

4. 22 > 78

I would say it would be the 4th option because she can only spend less than 78.

I can be very incorrect though, don't depend on me that much. Just make sure to think about my answer and what you would answer.
