The total cost of a jacket and a pair of shoes was $52.95. If the price of the jacket was $3.87 less than the pair of shoes, wha

abruzzese [7]

The price of jacket was $24.54

Step-by-step explanation:

Let,

Cost of jacket = x

Cost of pair of shoes = y

According to given statement;

x+y=52.95 Eqn 1

x = y-3.87 Eqn 2

Putting value of x from Eqn 2 in Eqn 1

$(y-3.87)+y=52.95\\y-3.87+y=52.95\\2y=52.95+3.87\\2y=56.82\\$

Dividing both sides by 2

$\frac{2y}{2}=\frac{56.82}{2}\\y=28.41$

Putting y=28.41 in Eqn 2,

$x=28.41-3.87\\x=24.54$

The price of jacket was $24.54

Find the values of x for which the combined function h(x) = is undefined if f(x) = 5x + 1 and g(x) = x2 - 9.

Rama09 [41]

We need to know the definition of the "combined function" h(x). I'm going to guess--by looking at answers--that the function is $h(x)=\frac{f(x)}{g(x)}$ making it

$h(x)=\frac{5x+1}{x^2-9}$

This function is undefined wherever the denominator is equal to 0 (division by zero is undefined). Factor the denominator.

$h(x)=\frac{5x+1}{(x+3)(x-3)}$

The two values of x that make the denominator 0 are 3 and -3, otherwise written $x=\pm 3$ .

rodikova [14]

Answer:

a) 0.04

b) 0.19

c) 0.01

d) 0.8

Step-by-step explanation:

Hi,

Let's make our data, considering two rules of probability:

The total probability of any event is 1.
Percentages are converted to decimal.

P(M) = 0.95
P(M')=0.05
P(B)=0.80
P(B')=0.20

- where M → Main Engine works, B → Back Up Engine works, M' → Main Engine will not work and B' → Back Up Engine will not work.

Remember for cases with and, we multiply; for cases with or, we use addition.

a) For this part, we know that Main Engine will work and Back-up engine will not work:

P(M' and B): 0.05 x 0.80 = 0.04

b) Back up will not work and Main will work:

P(M and B') = 0.20 x 0.95 = 0.19

c) We know the probability of entire component working, which is 0.99.

So to find the probability of entire component failing, we need to subtract 0.99 from 1. (Since the total probability is always 1)

P(Entire component will fail) = 1 - 0.99 = 0.01

d) This is a typical case of conditional probability, to calculate a conditional probability we use the following formula: $P(A|B) = \frac{P(A\ and\ B)}{P(B)}$
