A possible solution of the system of inequalities is 5 dimes and, 8 nickels

<h3>How to determine a possible solution?</h3>

From the question, the given parameters are:

Number of coins = Not less than 12

Worth = At most $0.95

Represent dime with x and nickels with y

So, we have the following inequalities

x + y >= 12

0.1x +0.05y <= 0.95

Next, we plot the graph of the inequalities (see attachment)

From the graph, we have a possible solution to be (5, 8)

This is so because this point is in the shaded region

In a standard normal distribution, about _________% of the scores fall above a z-score of 3.00

Katarina [22]

The normal rule to remember is 68-95-99.7, i.e. plus or minus three sigma corresponds to 99.7% of the probability. That leaves 0.3% in the two tails, or 0.15% in the tail above 3 sigma.

Answer: 0.15%

Option C: $y = \frac{1}{2}x+\frac{5}{2}$ is the right answer

Step-by-step explanation:

Given points are:

(x1,y1) = (-1,2)

(x2,y2) = (3,4)

First of all, the slope has to be found

$m =\frac{y_2-y_1}{x_2-x_1}\\=\frac{4-2}{3+1}\\= \frac{2}{4}\\=\frac{1}{2}$

The slope-intercept form of line is:

$y = mx+b$

Putting the value of m

$y = \frac{1}{2}x+b$

Putting (3,4) in equation

$4 = \frac{1}{2}(3) +b\\4 = \frac{3}{2} +b\\b = 4 - \frac{3}{2}\\= \frac{8-3}{2}\\=\frac{5}{2}$

Putting the value of b

$y = \frac{1}{2}x+\frac{5}{2}$

Hence,

Option C: $y = \frac{1}{2}x+\frac{5}{2}$ is the right answer

Use the equation Y= 11 - 5X to find y when x=7.

kap26 [50]

Plug in x = 7. Then use the order of operations (PEMDAS) to simplify
y = 11 - 5*x
y = 11 - 5*7 .... x has been replaced with 7 (since x = 7 is given)
y = 11 - 35
y = -24

Given P(A) = 0.8, P(B) = 0.51 and P(ANB) = 0.468, find the value of

masha68 [24]

Answer:

Step-by-step explanation:

P(BA)=P(B)+P(A)-P(AnB)

= 0.51+0.8-0.468

=1.31-0.468

=0.842

P(BA) = 0.842
