Find the indicated z score. The graph depicts the standard normal distribution with mean 0 and standard deviation. Shaded area is 0.06945

Please show work!

Answer:

Step-by-step explanation:

The area of the larger rectangle is (4)(5)=20.

The area of the top left right triangle is (1/2)(2)(5)=5.

The area of the top right right triangle is (1/2)(2)(1)=1.

The area of the bottom right triangle is (1/2)(4)(4)=8.

So A = 20 - 5 - 1 - 8 = 15 - 9 = 6.

Answer:

Step-by-step explanation:

area=π r²

=π×15²

=225 π cm²

Answer:

LM = 22

Step-by-step explanation:

11(44) = (LM)^2

484 = (LM)^2

LM = √484 = 22

Answer:

LM = 22

Step-by-step explanation:

If a tangent segment and a secant segment are drawn from an exterior point to a circle, then the square of the measure of the tangent segment is equal to the product of the measures of the external secant segment and the secant segment.

So for this circle,

So LM² = NM · OM

Given:

  LM² = 11 · 44 = 484

⇒ LM = √484 = 22

Answer: A

Step-by-step explanation:

The triangles are similar by AA. Angles BPA and CPD are congruent because they are vertical angles, and angles ABP and CDP are congruent because all right angles are congruent.

Answer:

The results are the opposite sign of x1 and x2.

[tex]lenght \: = (x - 8) \: and \: width \: = (x - 9)[/tex]

Pulling out like terms

3.1 Pull out like factors :

8g2 - 10g - 12 = 2 • (4g2 - 5g - 6)

Trying to factor by splitting the middle term

3.2 Factoring 4g2 - 5g - 6

The first term is, 4g2 its coefficient is 4 .

The middle term is, -5g its coefficient is -5 .

The last term, "the constant", is -6

Step-1 : Multiply the coefficient of the first term by the constant 4 • -6 = -24

Step-2 : Find two factors of -24 whose sum equals the coefficient of the middle term, which is -5 .

-24 + 1 = -23

-12 + 2 = -10

-8 + 3 = -5 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -8 and 3

4g2 - 8g + 3g - 6

Step-4 : Add up the first 2 terms, pulling out like factors :

4g • (g-2)

Add up the last 2 terms, pulling out common factors :

3 • (g-2)

Step-5 : Add up the four terms of step 4 :

(4g+3) • (g-2)

Which is the desired factorization

Final result :

2 • (g - 2) • (4g + 3)

Answer:

B

Step-by-step explanation:

Simply choose an x coordinate and plug it into the equations from the choices given.

i.e. where x=1

y=2(1)^2 - 4(1)

y= 2-4

y= -2

it can then be seen that where x=1 on the graph, y= -2 aligns perfectly

Answer:

B

Step-by-step explanation:

In y = 2x^2-4x, we put y = 0 to represent the intersection points on the x-axis of the graph. (Since y = 0 is always on the x-axis)

For 2x^2-4x = 0, using the quadratic formula, we get x = 0 and x = 2.

This matches the int. points on the graph.

Step-by-step explanation:

Which expression is equivalent to 486 – 9 + 6 + 33 × 2?

486 – 9 + 6 + 33 × 2

486 – 9 + 6 + 66

477 + 6 + 66

549

D . (486 – 9 + 6) + (33 × 2)

      477 + 6 + 66

               549

Hope this helps!

Part (a)

x = number of adults

y = number of students

5x = amount all of the adults paid ($5 each)

2y = amount the students paid ($2 each)

5x+2y = total amount of money for adults and students combined

The total amount (5x+2y) must be more than $150

So we end up with 5x+2y > 150 as the inequality.

This inequality involves the boundary line 5x+2y = 150 which goes through the y and x intercepts of (0,75) and (30,0) respectively. We use a dashed line for the boundary to mean that points on the boundary are not included as solution points.

We shade above the dashed boundary line to finish off the graph.

Refer to figure (a) shown below.

========================================================

Part (b)

x = number of adults

y = number of students

x+y = total number of people

120 seats is the max capacity so x+y cannot exceed this value.

x+y = 120 or x+y < 120

Or in short x+y ≤ 120 is the inequality

This involves the boundary line x+y = 120 which goes through the y and x intercepts of (0,120) and (120,0). We shade below the solid boundary line.

Refer to figure (b) shown below.

========================================================

Part (c)

Now imagine we overlapped the blue region from part (a) and the red region from part (b)

We'll get the purple region shown in figure (c). At this point, I'm only considering cases when x ≥ 0 and when y ≥ 0. It's not possible to have a negative number of people, so that's why we focus on the upper right quadrant of the xy grid.

This purple region consists of all (x,y) points that make ALL of the inequalities to be true. Exclude any points on the dashed boundary.

For example, if we picked the point (x,y) = (50,40) then this point is in the purple region. We can confirm its a solution by checking each inequality.

5x+2y > 150

5*50+2*40 > 150

250+80 > 150

330 > 150  .... which is true

and,

x+y ≤ 120

50+40 ≤ 120

90 ≤ 120 ... which is also true

Furthermore, both x and y are nonnegative making x ≥ 0 and y ≥ 0 to be true as well. Every inequality mentioned is true for (x,y) = (50,40) to fully confirm the solution point. There are other possible solutions such as (40,60) and (80,20) which I'll let you verify.

If we stick to the (50,40) from earlier, then this means 50 adults and 40 students went to the concert.
