Answer:

\huge \boxed{x=-3 \ \mathrm{and} \ y=17}

\rule[225]{225}{2}

Step-by-step explanation:

Subtracting both equations:

    5x + y = 2

 -  (4x + y = 5)

————————

1x + 0y = -3

x = -3

Substituting x = -3 for the second equation:

4(-3) + y = 5

Solving for y.

-12 + y = 5

y = 17

\rule[225]{225}{2}

The average cost of an IRS Form 1040 tax filing at Thetis Tax Service is $138.00. Assuming a normal distribution, if 77 percent
jek_recluse [69]

Answer:

22.97

Step-by-step explanation:

Given that the average cost of an IRS Form 1040 tax filing at Thetis Tax Service is $138.00.

Let x be the average cost an IRS Form 1040 tax filing at Thetis Tax Service

P(X is given

From std normal distribution table we find 77th percentile z value.

z=0.74

Corresponding X value = 155

i.e. 0.74=\frac{155-138}{s} where s is the std deviation

Simplify to get

Std deviation  = \frac{17}{0.74} \\=22.97

A special deck of cards has ten cards. Four are green, three are blue, and three are red. When a card is picked, its color of it
nata0808 [166]

Answer:

P(A) = 3/20

Step-by-step explanation:

P(A)=P(blue)P(head)=(3/10)(1/2)=3/20

as there are 10 cards in total, out of which 3 are blue so the probability to get the blue card is, P(blue) = 3/10. and the probability of getting a head when a coin is tossed is P(head) = 1/2.

So in total

P(A) = P(blue)*p(head) = (3/10)*(1/2) = 3/20 = 0.15
