The board of examiners that administers the real estate broker examination in a certain state found that the mean score on the t

nata0808 [166]

Z-score for 80% to pass = -0.842.
$-0.842=\frac{X-426}{72}$
-60.624 = X - 426
X = 426 - 60.624
X = 365
Therefore the required passing score is 365.

What additional information is needed to determine that ΔABC ≅ ΔEDC using the HL method of congruence? answers: A) ≅ B) No addit

Savatey [412]

Answer:

AC congruent to EC

Step-by-step explanation:

This problem is asking specifically to prove triangles congruent using HL.

HL is a method of proving triangles congruent. HL stands for Hypotenuse-Leg. If you can show that the hypotenuse and leg of one right triangle are congruent to the hypotenuse and leg, respectively, of another triangle, then the triangles are congruent.

Looking at triangle ABC and EDC, we see that the legs AB and ED are congruent. We already have a pair of corresponding congruent legs. Now we need a pair of hypotenuses.

You need AC congruent to EC.

Ruby buys 24 books and 5 pens.she pays with a 500 rupee note and get rs90 as change.shania bought 12 books and 10 pens for rs280

just olya [345]

The cost of one pen is Rs 15.

It is given that Ruby paid with a 500 rupee note and got Rs 90 back.

This means that she spent 410 rupees.

Therefore the cost of 24 books and 5 pens is Rs 410.

Let the cost of books be x and the cost of pens be y.

Therefore, we can form the following equations:

24x + 5y = 410 (1)

12x + 10y = 280 (2)

We have to find the value of y.

Multiply the second equation by 2:

24x + 20y = 560 (3)

Now subtract the first equation from the third equation:

24x + 20y - 24x - 5y = 560 - 410

15y = 150

y = 15.

The variable y represents the cost of one pen.

This means that the cost of one pen is Rs 15.

Therefore, we have found that the cost of one pen is Rs 15.

A fair die is cast four times. Calculate

solmaris [256]

Step-by-step explanation:

<h2>You can solve this using the binomial probability formula.</h2><h2>The fact that "obtaining at least two 6s" requires you to include cases where you would get three and four 6s as well.</h2><h2>Then, we can set the equation as follows:</h2><h2> </h2><h2>P(X≥x) = ∑(k=x to n) C(n k) p^k q^(n-k) </h2><h2>n=4, x=2, k=2</h2><h2>when x=2 (4 2)(1/6)^2(5/6)^4-2 = 0.1157</h2><h2>when x=3 (4 3)(1/6)^3(5/6)^4-3 = 0.0154</h2><h2>when x=4 (4 4)(1/6)^4(5/6)^4-4 = 0.0008</h2><h2>Add them up, and you should get 0.1319 or 13.2% (rounded to the nearest tenth)</h2>
