5 0

Answer:

5

8

14

Step-by-step explanation:

1. 4^{0} + 2 \times 3 - 2 = 1 + 6 - 2 = 5 (Answer)

{As we know that a^{0} = 1 for a ≠ 0}

2. 2^{2} + 10 - 3 \times 2 = 4 + 10 - 6 = 8 (Answer)

{We know, a^{2} = a \times a}

3. 9 + 3^{2} - 1 \times 4 = 9 + 9 - 4 = 14 (Answer)

Note: When there is no brackets, we perform the operation of '×' and '÷' first and then we perform the operation of '+' or '-'

The volume of a sphere is 500pi/3 inches cubed. What is the diameter of the sphere?
barxatty [35]
  • Answer:

<em>10 inches</em>

  • Step-by-step explanation:

<em>Hi there ! </em>

<em><u>volume of a sphere formula</u></em>

<em>V = 4π·r³/3</em>

<em>3V = 4π·r³</em>

<em>r³ = 3V/4π</em>

<em>replace</em>

<em>r³ = (3·500π/3)/4π</em>

<em>= 500π/4π</em>

<em>= 125</em>

<em>r³ = 125</em>

<em>r³ = 5³</em>

<em>r = 5 inches</em>

<em>d = 2r = 2×5in = 10 inches</em>

<em>Good luck !</em>

All 10,000 California students in the beginning of 8th grade are given an entrance exam that will allow them to attend a top aca
lys-0071 [83]

Answer:

1.32% of students have the chance to attend the charter school.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

This year the mean on the entrance exam was an 82 with a standard deviation of 4.5.

This means that \mu = 82, \sigma = 4.5

a.What is the percentage of students who have the chance to attend the charter school?

Students who achieve a score of 92 or greater are admitted, which means that the proportion is 1 subtracted by the pvalue of Z when X = 92. So

Z = \frac{X - \mu}{\sigma}

Z = \frac{92 - 82}{4.5}

Z = 2.22

Z = 2.22 has a pvalue of 0.9868

1 - 0.9868 = 0.0132

0.0132*100% = 1.32%

1.32% of students have the chance to attend the charter school.
