Becky can make 9 scoops of ice cream

4 1/2 = 4.5
1/2 = 0.5
4.5/0.5=9

Use the given values of n an p to find the minimum usual value mean - 2standard deviations and the maximum usual value. N= 1056,

Answer:

The minimum usual value: 818.803

The maximum usual value: 870.797

The population mean: 844.8

The standard deviation: 12.9985

Step-by-step explanation:

The parameters provided for the Binomial Distribution are:

n=1056, p=0.80

The population mean can be computed as:

μ = n ⋅ p

= 1056 × 0.80 = 844.8

The population variance is obtained by:

σ² = n ⋅ p ⋅ (1 − p)

= 1056 × 0.80 × 0.2 = 168.96

The standard deviation can be computed by taking the squared root of the variance:

σ = $\sqrt{n.p.(1-p)}$

= $\sqrt{168.96}$

= 12.9985

The minimum usual value: μ - 2σ = 844.8 - 2(12.9985)

= 844.8 - 25.997

= 818.803

The maximum usual value: μ + 2σ = 844.8 + 2(12.9985)

= 844.8 + 25.997

= 870.797

Answer:

C) 25%

Step-by-step explanation:

let salt be 's'

let water be 'w'

$\frac{s+1}{w+s+1} = 33\frac{1}{3} \\\\\frac{s+1}{w+s+1} = \frac{1}{3} \\\\\frac{w + s + 1}{3} = s+1\\\\3s +3 = w+s+1\\w = 2s+2\\\\\frac{s+1}{w+1+s+1} = \frac{3}{10} \\\\\frac{3(w+s+2)}{10} = s+1\\\\3w+3s+6 = 10s+10\\**w = 2s+2\\3(2s+2) + 3s + 6 = 10s+10\\\\6s+6+3s+6 = 10s+10\\9s+12 = 10s+10\\-s = -2\\s = 2\\\\w= 2s+2\\w=2*2+2\\w = 6\\\\\frac{2}{2+6} = \frac{2}{8} = 0.25$
