Answer:

a. 4x = 332

b. 83 students

Step-by-step explanation:

Write equation:

4x = 332

Since we know that each ticket per student is $4, we can use "x" as our variable for the number of students

Using the normal distribution, it is found that the prediction is that the largest number of people would receive an IQ score of 100 on that test.

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

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

IQ scores have mean of 100, and since in the normal distribution most measures are around the mean, an IQ score of 100 is the prediction.

Answer:

Step-by-step explanation:

the angle of measure 4x + 12 and the angle of measure 64 are Vertically opposite angles then they are equal in measure

therefore

4x + 12 = 64

⇔ 4x = 64 - 12

⇔ 4x = 52

⇔ x = 52/4

⇔ x = 13

Exact Form:

Decimal Form:

2.7

Mixed Number Form:

2 7/10

Answer:

4 1/2 - 1 8/10 =  2 7/10

Step-by-step explanation:

Step 1 : Start by making the mixed fraction into improper fractions

4 1/2 = 9/2

(For the fraction 1 8/10,  make sure to simplify 8/10!)

9/2 - 1 4/5 = 9/2 - 9/5

Step 2: Next find a common denominator for both the improper fractions.

9/2 x 5/5 = 45/10

9/5 x 2/2 = 18/10

45/10 - 18/10 = 27/10

Step 3: Now, make the improper fraction into a mixed number

27/10 = 2 7/10

So this shows us that 4 1/2 - 1 8/10 =  2 7/10! Hope this helps! :D

Answer:

(a) [tex]\sf -16r^2+20r-4=0[/tex]

(b)  r = 1,  r = 1/4

Step-by-step explanation:

Given equation:   [tex]\sf h=-16r^2+20r-4[/tex]

where:

Question (a)

The ball will hit the ground when h = 0

[tex]\sf \implies-16r^2+20r-4=0[/tex]

Question (b)

To factor [tex]\sf -16r^2+20r-4=0[/tex]

Divide both sides by 4:

[tex]\sf \implies-4r^2+5r-1=0[/tex]

Swap signs:

[tex]\sf \implies 4r^2-5r+1=0[/tex]

Split middle term:

[tex]\sf \implies 4r^2-4r-r+1=0[/tex]

Factorize the first two terms and the last two terms separately:

[tex]\sf \implies 4r(r-1)-(r-1)=0[/tex]

Factor out common term (r - 1):

[tex]\sf \implies (4r-1)(r-1)=0[/tex]

Therefore:

[tex]\sf \implies (4r-1)=0 \implies r=\dfrac14[/tex]

[tex]\sf \implies (r-1)=0 \implies r=1[/tex]

Step-by-step explanation:

I'm not sure if it's right but this is how I worked it out,

the box's contents are 4.2 pounds in total,

therefore in a fraction it would be 6/42

you turn a fraction into a percentage you do the numerator divided by the denominator

6÷42=0.142857(decimal form)

now you just turn it into a percentage

14.28%
