**Answer:**

15 boys selected

**Step-by-step explanation:**

**Given**

[tex]N =11000[/tex] --- The population

[tex]n = 100[/tex] --- The sample selected

[tex]p =0.152[/tex] -- The proportion of boys

**Required**

The expected number of boys selected

**The expected number is calculated by multiplying the sample size by the proportion of boys.**

**So, we have:**

[tex]Boys = p * n[/tex]

[tex]Boys = 0.152 * 100[/tex]

[tex]Boys = 15.2[/tex]

[tex]Boys = 15[/tex]** --- approximated**

An exam has 40 multiple-choice questions, each with 5 choices. Only 1 of the 5 choices for each

question is correct. If you used a table of random digits to randomly choose your answer on all

questions, about how many answers would you expect to get correct?

Select one:

O

a. 40

O

b. 0

0

C. 20

d. 8

e. 5

I will give a brilliant if the answer was correct

Please helppp

**Answer:**

D.8

**Step-by-step explanation:**

Since your chance of success is only 1 out of 5 or rather, 20%, so

40 divided by 5 equals 8, so the answer is D.

(Of course, this is just what SHOULD happen, not what CERTAINLY can happen.)

Expected number of **answers** to be correct = 8.

**Measure** of the **likelihood** of an event happening is called Probability. Probability can be between 0 to 1. 0 means the event cannot happen, 1 indicates the specific event. The **sum** of the probabilities of all events in the sample space is 1.

**Probability** can be defined as the **ratio** between the number of **favorable** outcomes and the total number of outcomes of an event. For a **trial** with “n” number of results, the number of **favorable** outcomes can be denoted by x. The **formula** for calculating the probability of an event is as follows.

Probability (Event) = Favorable Outcome/Total Outcome = x/n

Given,

Number of questions = 40

One of 5 choices is correct

then, **probability** of getting correct option = 1/5

Number of correct answers = 40 × 1/5 = 8

Hence, 8 **answers** are expected to be correct.

Jim got 46 out of 60 correct on a test. What is the best estimate of the percent Jim got correct ?

**Answer-**

**77**

**Step-by-step explanation:**

i rounded 76.67% (which was the exact percentage of 46 out of 60)

2- 77%

**Answer:**

About 76.5% (77%)

**Step-by-step explanation:**

well start with the simple fractions. 40/60 is 2/3 which is 66.66666 repeating.

If we know it increased at least 5 more that is 45/60 which is 3/4, since 15 * 4 = 60, so 15 * 3 = 45.

We could say without getting too specific that every point will have about a 1.5 or more % increase since if it was out of 100 points every 1 question is +1 % and 50 points every question is +2 %. Since this is 60 it will be roughly about 1.6%

Ok the point is, about 76.5% (77%)

5. Casey's bank account offers him 2% interest every year, given by the equation

g(x)= 1.02. If Casey deposits $5,625 in his bank account, which equation

represents the amount of money that will be in his account after 2 years?

Answer:

Casey will have 5852.25 in his bank account after 2 years.

Step-by-Step Explaination:

2%=0.02

0.02*5625=112.5

112.5+5625=5737.5

0.02*5737.5=114.75

114.75+5737.5=5852.25

**Answer:**

1) A store sells small and large TV sets in the ratio 2:3. The total stock is 70

sets.1) How many small and large sets are in stock? 2)If the number of large

sets is increased by 8,what is the new ratio of small to big*

**Answer:**

(a)

[tex]Small = 28[/tex]

[tex]Large = 42[/tex]

**(b)**

[tex]Ratio = 14 : 25[/tex]

**Step-by-step explanation:**

**Given**

[tex]L = Large\\ S = Small[/tex]

[tex]S : L = 2 : 3[/tex]

[tex]Total = 70[/tex]

**Solving (a): Number of each set.**

**The small set is calculated as:**

[tex]Small = \frac{S}{S + T} * Total[/tex]

[tex]Small = \frac{2}{2+3} * 70[/tex]

[tex]Small = \frac{2}{5} * 70[/tex]

[tex]Small = 0.4 * 70[/tex]

[tex]Small = 28[/tex]

**Using complement rule.**

[tex]Large = Total - Small[/tex]

[tex]Large = 70 - 28[/tex]

[tex]Large = 42[/tex]

**Solving (b): Increase large by 8.**

**The ratio is then calculated as:**

[tex]Ratio = Small : Large + 8[/tex]

[tex]Ratio = 28 : 42 + 8[/tex]

[tex]Ratio = 28 : 50[/tex]

**Divide by 2**

[tex]Ratio = 14 : 25[/tex]

Is this for a Trig class? just wondering

**Step-by-step explanation:**

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

we want to find the Hypotenuse (Hyp) and are given an angle and the adjacent side (adj) sooo use CAH , b/c it has all of the pieces

Cos(37) = Adj / Hyp

Cos(37) = 11 / Hyp

swap Cos(37) and Hyp... an algebra trick you should know from college algebra or where ever you learned algebra

Hyp = 11 / Cos(37)

now solve with your handy TI 83 / 84 / 89 calculator :) if you don't have one go get one . :D get the 89 if you are going into engineering classes... the 83 /84 if not. (obviously there are many many other good choices, i'm not really a calculator salesman on the side :D )

Hyp = 13.77349...

Hyp = 13.8 ( rounded to nearest 10th ) :)

0.79863551 = 11/x

x = 11/0.79863551 = 13.77 or 13.8

The length of a chord is 22 cm and that chord is 5 cm from the center of the circle. What is the length of the diameter ?

**Answer:**

The circle's diameter is approximately 24.2 cm

**Step-by-step explanation:**

You can use the Pythagorean theorem to solve this, my realising that the 5cm distance of the chord represends one side of a right triangle, half the chord's length is the other side, and the hypotenuse of the two is the circle's radius. With that we can say:

r = √(11² + 5²)

r = √(121 + 25)

r = √146

Now we can double that to get the diameter:

r = 2√146

r ≈ 24.2

table holds 8 guests, what is the least number of tables

you must have to seat all of the guests?

The least number of tables would be 31

Can anyone help me with this all i need is an explanation on how to do it?

**Answer:**

x = 24

**Step-by-step explanation:**

Ok so basically the angles shown are vertical angles

One of the properties of vertical angles is that they are congruent

That being said we would use this equation to solve for x

120 = 5x

then you would solve for x

*isolate the variable*

step 1 divide each side by 5

120/5=24

5x/5=x

we're left with x = 24

At a bird sanctuary, the population of bluebirds is 120 and is increasing 4% annually. How many bluebirds will there be in 8 years?

The answer is: 158 birds

4% of 120 is 4.8 birds. So the population is increasing by 4.8 each year. 4.8 x 8 years = 38.4

120 + 38.4 = 158.4

4% of 120 is 4.8 birds. So the population is increasing by 4.8 each year. 4.8 x 8 years = 38.4

120 + 38.4 = 158.4

Solve for x.

60

10

20

120

**Answer:**

x = 10

**Step-by-step explanation:**

Let's draw the center of the circle S and the segments SE and SD.

SE is perpendicular to EF (as EF is tangent to circle).

That means FED + DES = 90deg

We also know that DSE = 120deg

And because the SED is an isosceles triangle, we know that angle measures for DES and SDE are equal.

DES = (180deg - 120deg) / 2 = 30deg

FED = 90deg - DES = 90deg - 30deg = 60deg
