In a trapezoid, the midline is the average of the two bases.

PW = (YZ + TM) / 2

29 = (23 + 11x + 2) / 2

58 = 23 + 11x + 2

58 = 25 + 11x

11x = 33

x = 3

Hope this helps!

Answer:

2/3

Step-by-step explanation:

so the inverse takes us from the range to the domain... they tell us that  f(4) goes to 5.. so if we were to take the inverse  f\left \[-1} \atop(5)  it takes us back to 4... and the slope at 4 or the derivative was 2/3 so that's what we get for f\left \ {{-1} \atop '(5)  :)

Arithmetic mean of marks (out of 25) scored by 10 students was 15. One of the student, named Karishma enquired the other 9 stude
erastova [34]

Answer:

Krishna's marks x marks

so...

xˉ=15

xˉ=15n=10

xˉ=15n=10∑x=x+x−8+x−6+x−3+x−1+x+x+2+x+3+x+4+x+6=10x−3

15=10x-3/10

150+3=10x

x=150/10=15.3 marks

<em><u>Krishna scored 15.3 marks.</u></em>

Y varies inversely with x. When x = 3 then y = 5. Write a function to represent this relationship.
Mariulka [41]

Answer:

<em>The function to represent this relationship will be:  y= \frac{15}{x}</em>

Step-by-step explanation:

y  varies inversely with  x. That means......

y= \frac{k}{x}..............................(1)  

where k is a proportional constant.

Given that, when x=3, then y=5

Plugging these values into the above equation, we will get.....

5=\frac{k}{3}\\ \\ 5(3)=\frac{k}{3}(3)\\ \\ 15=k

Now plugging this k=15 into equation (1).....

y= \frac{15}{x}

So, the function to represent this relationship will be:  y= \frac{15}{x}

What is the probability that the number of “HEADs” on these four coins is equal to 3? (4 points)
slavikrds [6]

Answer:

a. \frac{1}{4}  

Step-by-step explanation:  

We are asked to find the probability of getting 3 heads on 4 flips.

\text{Probability}=\frac{\text{Number of favorable outcomes}}{\text{Total number of possible outcomes}}

Since we know that flipping a fair coin has 2 equally likely possible outcomes, so flipping four coins will have 2*2*2*2=16 possible outcomes.

Sample space of possible outcomes.

HHHH, HHHT, HHTH, HHTT, HTHH, HTHT, HTTH, HTTT,

THHH, THHT, THTH,THTT, TTHH, TTHT, TTTH, TTTT.

We can see that there are 4 favorable outcomes of getting heads.

\text{Probability of getting 3 heads}=\frac{4}{16}

\text{Probability of getting 3 heads}=\frac{1}{4}

Therefore, the probability of getting 3 heads on 4 coins will be \frac{1}{4} and option a is the correct choice.
