Answer: 50/3 or 16 2/3 or 16.67

Step-by-step explanation:

Given

18-3k÷9

Substitute [k] value into the given expression

 18-3k÷9

=18-3(4)÷9 ⇒ Substitute the value

=18-12÷9 ⇒ Expand the parenthesis

=18-4/3 ⇒ First do division

=54/3-4/3 ⇒ Convert an integer into a fraction

=50/3=16 2/3=16.67

Answer:

Step-by-step explanation:

The mean for 2018 scores is:

[tex]M ean ( \overline X) = \dfrac{\sum x_i}{n}[/tex]

[tex]M ean ( \overline X) = \dfrac{74 + 78+79+77+75+73+75+77}{8}[/tex]

[tex]M ean ( \overline X) = \dfrac{608} {8}[/tex]

[tex]\mathbf{M ean ( \overline X) = 76}[/tex]

The standard deviation for 2018 scores is:

[tex]s = \sqrt{\dfrac{\sum ( x_i - \bar x)^2}{n- 1} }[/tex]

[tex]s = \sqrt{\dfrac{ ( 74 -76)^2+( 78 -76)^2+( 79 -76)^2+...+( 73 -76)^2+( 75 -76)^2+( 77 -76)^2}{8- 1} }[/tex]

[tex]s = \sqrt{\dfrac{30}{7} }[/tex]

s = 2.07

The mean and standard deviation for the year 2018 scores is:

                                     2018

Mean                                 76

Standard deviation       2.07

The mean for 2019 scores is:

[tex]M ean ( \overline X) = \dfrac{\sum x_i}{n}[/tex]

[tex]M ean ( \overline X) = \dfrac{71 + 70+75+77+85+80+71+79}{8}[/tex]

[tex]M ean ( \overline X) = \dfrac{608} {8}[/tex]

[tex]\mathbf{M ean ( \overline X) = 76}[/tex]

The standard deviation for 2019 scores is:

[tex]s = \sqrt{\dfrac{\sum ( x_i - \bar x)^2}{n- 1} }[/tex]

[tex]s = \sqrt{\dfrac{ ( 71 -76)^2+( 70 -76)^2+( 75-76)^2+...+( 80 -76)^2+( 71 -76)^2+( 79 -76)^2}{8- 1} }[/tex]

[tex]s = \sqrt{\dfrac{194}{7} }[/tex]

s = 5.26

The mean and standard deviation for the year 2019 scores is:

                                     2019

Mean                                 76

Standard deviation       5.26

Difference: Both the two years have the same mean but the 2019 scores have higher variation as compared to 2018 scores.

Thus, the variation in scores was higher in 2019.

Answer:

8

6/8 and 3/8

4 = 2²

8 = 2³

LCM = 2 × 2 × 2

LCM = 8

The Least common denominator of the fraction numbers 3/4 and 3/8 is 9/24

The least common denominator (LCD) of 3/4 and 3/8 is the smallest number that both 4 and 8 can divide into evenly.

The prime factorization of 4 is 2 x 2, and the prime factorization of 8 is 2 x 2 x 2.

Next, we list the prime factors of each denominator and identify any factors that are common to both:

4: 2 x 2

8: 2 x 2 x 2

The common factors are 2 x 2, which means that we only need to include one set of these factors in the LCD.

So, the LCD of 3/4 and 3/8 is:

LCD = 2 x 2 x 2 x 3 = 24

For 3/4, we need to multiply both the numerator and denominator by 6 to get:

3/4 = (3 x 6)/(4 x 6) = 18/24

For 3/8, we need to multiply both the numerator and denominator by 3 to get:

3/8 = (3 x 3)/(8 x 3) = 9/24

Answer:

G. 12 cm

Step-by-step explanation:

Length of one leg of right triangle = a = 9 cm

Length of hypotenuse = c = 15 cm

Length of the other leg = b = ?

Applying pythagorean theorem, c² = a² + b², we have:

15² = 9² + b²

15² - 9² = b²

144 = b²

b = √144

b = 12

Answer:

1 mile = 0.2 hours

Step-by-step explanation:

Given that,

Eddie can travel 20 miles in 4 hours.

We need to find how many hours does it take Eddie to travel 1 mile.

20 mile = 4 hours

1 mile = (4/20) hours

= 0.2 hours

So, to travel 1 mile will take 0.2 hours.

Answer:

48 pupils

Step-by-step explanation:

let the number of people in the class be x

⅚ of the number of pupils in a class is expressed as ⅚x

4 greater than three-quarters of the number in the class is expressed as 3/4x+4

Equating both expressions

⅚x = 3/4x + 4

5x/6 - 3x/4 = 4

(10x-9x)/12 = 4

x/12 = 4

x = 4*12

x = 48

Hence the number of pupils in the class​ is 48 pupils

Answer:Then 16x = 240, and x = 240/16 = 15. It will take 15 minutes to travel 12 miles.

Step-by-step explanation:

16 miles     =  12 miles

20 mins.        how many mins?

16    =   12       cross multiply       16? = 240   divide by 16     240 divided by 16 = 15 miles

20          ?                                                                                because 15 x 16 = 240

Answer:

It will take 15 minutes to travel 12 miles.

Step-by-step explanation:

Write and solve an equation of ratios:

16 miles     20 min

-----------  = -----------

12 miles          x

Then 16x = 240, and x = 240/16 = 15.

Answer: 125

The best prediction for the number of times a 4 will be drawn from the pile is:

A set of cards contains cards numbered 1 – 8.

So, the theoretical probability that 4 comes up is:

Ratio of Number of favorable outcome( outcome of 4) to the total umber outcome(i.e. 8 )

Hence, Theoretical Probability that 4 is drawn=1/8

Now, out of 1000 trials the best prediction of number of times 4 is drawn is:

(The probability of drawing 4)×(Number of experiments or trials)

=(1/8)×1000

=125

Answer:

[tex]\%Tip = 13.04\%[/tex]

Step-by-step explanation:

Given

[tex]Tip= \$31.29[/tex]

[tex]Bill = \$208.60[/tex]

Required

Determine the percentage of the tip

First, we calculate the amount paid

[tex]Amount = Tip + Bill[/tex]

[tex]Amount = \$31.29 + \$208.60[/tex]

[tex]Amount = \$239.89[/tex]

The percentage of the tip is then calculated using:

[tex]\%Tip = \frac{Tip}{Amount} * 100\%[/tex]

[tex]\%Tip = \frac{31.29}{239.89} * 100\%[/tex]

[tex]\%Tip = \frac{31.29* 100}{239.89} \%[/tex]

[tex]\%Tip = \frac{3129}{239.89} \%[/tex]

[tex]\%Tip = 13.04\%[/tex]

Answer:

n=-2

Step-by-step explanation:

Let's solve your equation step-by-step.

−3(3n+4)=6

Step 1: Simplify both sides of the equation.

−3(3n+4)=6

(−3)(3n)+(−3)(4)=6(Distribute)

−9n+−12=6

−9n−12=6

Step 2: Add 12 to both sides.

−9n−12+12=6+12

−9n=18

Step 3: Divide both sides by -9.

−9n

−9

=

18

−9

n=−2

Answer:

n = -2

Step-by-step explanation:

-3(3n + 4) = 6; multiply -3 to both 3n and 4.

-9n - 12 = 6; add 12 on both sides.

-9n = 18; divide -9 on both sides to isolate the variable n.

n = -2
