2 parts = 2 × $50 = $100 ← smaller share

Women comprise 83.3% of all elementary school teachers. In a random sample of 300 elementary school teachers, what is the probability that fewer than 260 are women?

Using the normal approximation to the binomial, it is found that there is a **0.9319 = 93.19% probability** that fewer than 260 are women.

In a** normal distribution** with **mean **[tex]\mu[/tex] and **standard deviation** [tex]\sigma[/tex], the **z-score** of a **measure X** is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

ItIn this problem:

Women compriseThe **mean **and the **standard deviation** for the approximation are given by:

[tex]\mu = np = 300(0.833) = 249.9[/tex]

[tex]\sigma = \sqrt{np(1 - p)} = \sqrt{300(0.833)(0.167)} = 6.46[/tex]

Using **continuity correction**, as the binomial distribution is discrete and the normal distribution is continuous, the **probability **that fewer than 260 are women is P(X < 260 - 0.5) = **P(X < 259.5)**, which is the p-value of Z when X = 259.5, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{259.5 - 249.9}{6.46}[/tex]

[tex]Z = 1.49[/tex]

[tex]Z = 1.49[/tex] has a p-value of 0.9319.

**0.9319 = 93.19% probability** that fewer than 260 are women.

A professional guitarist charges a flat amount for performances at restaurants and events. He played 6 performances over 2 weeks and made a total of $420. Write an equation and solve for the amount he makes for each performance.

**Answer:**

The guitarist makes **70$** a performance

**Step-by-step explanation:**

To find how much he makes per performance we need to make an equation where how much he makes per performance is **x**

The equation would be:

6×**x**=420

Then we would divide both sides by 6

6÷6×**x**=420÷6

which would make the equation

**x=70**

meaning that the guitarist makes 70$ per performance

Let performances be x

[tex]\\ \sf{:}\dashrightarrow 6x(2)=420[/tex]

[tex]\\ \sf{:}\dashrightarrow 12x=420[/tex]

[tex]\\ \sf{:}\dashrightarrow x=420/12[/tex]

10. The **sum **of 15 terms is -1.

11. The **sum **of 6 terms is 364

12. The **sum **of 10 terms is -682.

We have,

Sn =a (1 - [tex]r^n[/tex] ) ÷ (1 – r)

9. 12, -6, 3, .....

Here, r= -6/ 12= -1/2

So, S(9)

= 513/ 64

10.-1, +1, -.....

Here, r= 1/ (-1)= -1

So, S(15) = 1 (1- [tex](-1)^{15[/tex])/ (1 - (-1))

= -1

11. 1, 3, .....

Here, r = 3/1 = 3

So, S(6) = 1 (1- [tex](3)^{6[/tex])/ (1 - 3)

= 364

12. 2, -4, ...

Here, r= (-4)/ 2= -2

So, S(10) = -682

How much pure alcohol must a pharmacist add to 10 cm of a 10% alcohol solution to strengthen it to a 70% solution? ASAP

**20 cm³ **of** pure alcohol** is added to 10 cm of a 10% alcohol solution to strengthen it to a 70% solution.

Let** x** represent the** volume** of **pure alcohol **(100%) in cm³ needed to be added. Hence:

**x * 100% + 10 cm³ * 10% = 70% * (x + 10 cm³)**

x * 1 + 10 * 0.1 = 0.7 * (x + 10)

x + 1 = 0.7x + 7

x - 0.7x = 7 - 1

0.3x = 6

**x = 20 cm³**

Therefore **20 cm³ **of** pure alcohol** is added to 10 cm of a 10% alcohol solution to strengthen it to a 70% solution.

Which is not an option in the question so this question clearly has a problem.

First of all It's supposed to be "then" not "than," so I'm not sure who teaches math without even knowing this basic grammar.

Second of all, if the answer is 8:1 the question should be "If **each sides** of a cube is doubled" not "the lateral surface area." Come to think of it what even is lateral surface area of a cube if all sides of the cube is supposed to be same.

Or, if the answer is 2:1 then, it should be If height lateral surface area of a cube is doubled **by doubling the height and without changing the length and width**" But, then the the shape would no longer be a cube.

Who even wrote this garbage question what.

Mai makes her favorite shade of green paint by using 5 cups of blue paint for every 3 cups of yellow paint. Priya makes her favorite shade of green paint by using 7 cups of blue paint for every 5 cups of yellow paint. Whose favorite shade of green paint has more of a blue tint? Explain how you know.

**Answer:**

Priya

**Step-by-step explanation:**

Mai= 5:3 Priya=7:5

Mai= 15:15 Priya=21:15

The ratios above are blue:yellow so Priya's shade has more of a blue tint because it is 21:15 and Mai's is 15:15 so it is evenly spread.

Sara has $65 and wants to buy the following items from a store. Board game: $14.95 Building blocks: $25.49 Art kit: $35.79 At the store, all items are one-fourth off of the original price and there is a 5% sales tax. Sara wants to know if she can buy all of these items. Which statement is TRUE?

The correct statement is** Sara** can afford to purchase the **items **because the **final price** of the items is **$60.**

The first step is to determine the total cost of the** items** **Sara **wants to buy. The **total cost** can be determined by **adding **the cost of the items together.

**Total cost** = $14.95 + $25.49 + $35.79 = $76.23

The second step is to determine the cost of the items after the **discount. **

Price of the** items **= total cost x (1 - discount)

= total cost x (1 - 1/4)

total cost x 3/4

$76.23 x 3/4 = $57.17

The third step is to determine the cost of the **items **after **tax. **
