\frac{1}{3}Answer:

2/9

Step-by-step explanation:

given that Tyler selects one card from the three(4,5, and a King), and rolls a number cube.

We find that A the event of selecting one card and B getting a number on rolling a number cube are independent events.

No of cards = 3

Prob of selecting 5 from 3 cards = P(1,2,3, or 4) = \frac{2}{3}

When rolling a number cube (assuming fair) there is equally likely for all numbers to appear from 1 to 6

Prob of getting 5 =\frac{1}{6}

Prob of getting less than 5 =

Since these two events are independent,

the probability that she selects the 5, and rolls a number less than 5

= Product of probabilities

= \frac{1}{3}*\frac{2}{3}

=\frac{2}{9}

In kite WXYZ, measure of angle XWY=38° and measure of angle ZYW=15°
zlopas [31]

Answer:

∠ WXY = 127°

Step-by-step explanation:

We know that for a given kite shape has different vertex angles but the two non-vertex angles are the same.

Now, we are given a kite WXYZ and angle ∠ XWY = 38° and angle ∠ ZYW = 15°.

Therefore, the two vertex angles are (38 ×2) = 76° and (15 × 2) = 30° respectively.

Now, the sum of two non-vertex angles = 360° - 76° - 30° = 254°

And each of non-vertex angle is = \frac{254}{2} = 127°

{Since the two non-vertex angles are the same.}

Now, ∠ WXY is a non-vertex angle of the kite.

Hence, ∠ WXY = 127° (Answer)

I will give BRAINLIEST PLS HELP y = x + 1/2 and z = 2x - 3, which of the following is equivalent to y + yz? PLS HELP
STALIN [3.7K]

Answer:

y+yz is: 2x^2-2x-1

Step-by-step explanation:

Given expressions are:

y = x+\frac{1}{2}\\z = 2x-3

The given expressions are polynomials and we have to find the value of y+yz

First of all, we will find the product of y and z

We will use the distribution to find the product.

yz = (x+\frac{1}{2})(2x-3)\\= x(2x-3)+\frac{1}{2}(2x-3)\\= 2x^2-3x+x-\frac{3}{2}\\=2x^2-2x- \frac{3}{2}

The next step is to add y and yz

y+yz = (x+\frac{1}{2})+(2x^2-3x-\frac{3}{2})\\Combining\ like\ terms\\= 2x^2+x-3x+\frac{1}{2} -\frac{3}{2}\\=2x^2-2x + \frac{1-3}{2}\\=2x^2-2x+\frac{-2}{2}\\=2x^2-2x-1

The answer is not one of the options which i assume might be a typing mistake.

Hence,

y+yz is: 2x^2-2x-1
