Julli [10]

Answer:

Number of salsa jars you can buy is 8 jars

The number of bags of chips you can buy is 28 bags

Step-by-step explanation:

The question above is incomplete.

In other to complete it, we would have to make some assumptions.

You are in charge of buying the chips, which cost $2.50 per bag and salsa, which costs $4 per jar. The chips & salsa budget you are given totals $60. The inequality 2.5x + 4y less than or equal to 60 represents the possible combinations of chips (x) and salsa (y ) you can buy.

Hence, we solve for x and y

The inequality is given:

2.5x + 4y ≤ 60

2.5x + 4y = 60........ Equation 1

Let us assume that the total number of bags of chips - jar of salsa you can buy is equal to 20.

Hence:

x - y = 20...... Equation 2

x = 20 + y

Substitute 20 + y for x in Equation 1

2.5x + 4y = 60........ Equation 1

2.5(20 + y) + 4y = 60

50 + 2.5y + 4y = 60

Collect like terms

2.5y + 4y = 60 -50

6.5y = 50

y = 50/6.5

y = 7.6923076923

Approximately to the nearest whole number

Number of salsa jars you can buy is 8

From here, we can solve for x based on this assumptions

x - y = 20

x - 8 = 20

x = 20 + 8

x = 28

The number of bags of chips you can buy is 28 bags

A supplier delivers an order for 20 electric toothbrushes to a store. By accident, three of the electric toothbrushes are defect

krek1111 [17]

Answer:

The probability that the first two electric toothbrushes sold are defective is 0.016.

Step-by-step explanation:

The probability of an event, say <em>E </em>occurring is:

$P (E)=\frac{n(E)}{N}$

Here,

n (E) = favorable outcomes

N = total number of outcomes

Let <em>X</em> = number of defective electric toothbrushes sold.

The number of electric toothbrushes that were delivered to a store is, <em>n</em> = 20.

Number of defective electric toothbrushes is, <em>x</em> = 3.

The number of ways to select two toothbrushes to sell from the 20 toothbrushes is:

${20\choose 2}=\frac{20!}{2!(20-2)!}=\frac{20!}{2!\times 18!}=\frac{20\times 19\times 18!}{2!\times 18!}=190$

The number of ways to select two defective toothbrushes to sell from the 3 defective toothbrushes is:

${3\choose 2}=\frac{3!}{2!(3-2)!}=\frac{3!}{2!\times 1!}=3$

Compute the probability that the first two electric toothbrushes sold are defective as follows:

P (Selling 2 defective toothbrushes) = Favorable outcomes ÷ Total no. of outcomes

$=\frac{3}{190}\\$

$=0.01579\\\approx0.016$

Thus, the probability that the first two electric toothbrushes sold are defective is 0.016.
