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

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:

(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]

There are a couple of different ways we can do this: change the fraction into a decimal or multiply by the reciprocal.

Change the Fraction Into a Decimal

---3/4 = 0.75

So, instead of using the fraction, we can put it into decimal form. We will need to move the decimal point in both numbers though, making our division problem as follows:

20096 / 75 = ?

---The decimal point was moved two places to the right in order to make the former fraction a whole number.

Multiply by the Reciprocal

---To find the reciprocal, switch the numerator and denominator, essentially "flipping" the fraction upside down.

Another way of dividing by fractions is multiplying by the reciprocal. For example, dividing a number by 3 is the same thing as multiplying by 1/3. We can do the same in this problem. Instead of dividing by 3/4, we can multiply by 4/3, making our problem look as follows:

200.96/1 x 4/3 = ?

Answer: 803.84 / 3 = 267.9467

Answer:

x+15=180(being co-interior angle)

x=180-15

x=165

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

The true statements are m + 2.1 > n + 2.1, m - (-4) > n - (-4) and 9 + m > 6 + n

The inequality is given as:

m > n

When the same constant k is added to both sides of the inequality, we have:

m + k > n + k

This means that the following inequality is true

m + 2.1 > n + 2.1

When the same constant k is subtracted from both sides of the inequality, we have:

m - k > n - k

This means that the following inequality is true

m - (-4) > n - (-4)

Also, if a greater constant is added to m, then the inequality still remains the same.

This means that the following inequality is true

9 + m > 6 + n

Hence, the true statements are m + 2.1 > n + 2.1, m - (-4) > n - (-4) and 9 + m > 6 + n
