<span>m = 4a + 2c

a = 25; c = 5

Replace a with 25. Replace c with 5.
Then evaluate the expression.

m = 4 * 25 + 2 * 5

m = 100 + 10

m = 110

Answer: 110 meatballs are needed.</span>

Twelve percent of the population is left handed. Approximate the probability that there are at least 20 left-handers in a school
DochEvi [55]

Answer:

Step-by-step explanation:

We would assume a binomial distribution for the handedness of the population. Let x be a random variable representing the type of handedness in the population. The probability of success, p is that a randomly chosen person is left handed only. Then probability of failure is that a chosen person is not left handed only(right handed only or both).

p = 12/100 = 0.12

number of success, x = 20

n = 200

the probability that there are at least 20 left-handers is expressed as P(x ≥ 20)

From the binomial probability calculator,

P(x ≥ 20) = 0.84

The mass of each candy in a box is 5g. The mass of the empty box is 20g let T grams represent the total mass of the box and cand
grandymaker [24]

Answer:

\begin{center}\begin{tabular}{ c c } n & T\\ 0 & 20 \\  1 & 25 \\   2 & 30 \\   3 & 35 \\   4 & 40 \\  \end{tabular}\end{center}

Please refer to graph attached.

Step-by-step explanation:

Given that mass of each candy in the box is 5 gm.

Mass of empty box is 20 gm.

Total grams, T = 5n + 20

To find: A table of values and graph of the relation.

Solution:

The given equation is nothing but a Linear equation in two variables.

Let us try to create a table of values by putting some values of 'n' and then finding the values for Total grams 'T'.

Let us put n = 0 \Rightarrow T =5\times 0 +20 = 20

Let us put n = 1 \Rightarrow T =5\times 1 +20 = 25

Let us put n = 2 \Rightarrow T =5\times 2 +20 = 30

Let us put n = 3 \Rightarrow T =5\times 3 +20 = 35

Let us put n = 4 \Rightarrow T =5\times 4 +20 = 40

So, the table of values becomes:

\begin{center}\begin{tabular}{ c c } n & T\\ 0 & 20 \\  1 & 25 \\   2 & 30 \\   3 & 35 \\   4 & 40 \\  \end{tabular}\end{center}

We can see that the value of T is increasing with increasing values of 'n'.

Please refer to the attached image for the graph of given equation.

As it is a linear equation in two variables, it will be a straight line. It will be an increasing positive slope graph.
