The diagonals of square abcd intersect at e. if ae = 3x – 4 and bd = 10x – 48, find ac.

Mathematics

Answer:

AC = 52

Step-by-step explanation:

the diagonals of a square are congruent and bisect each other, hence

AC = BD

2(3x - 4) = 10x - 48

6x - 8 = 10x - 48 ( subtract 10x from both sides )

- 4x - 8 = - 48 ( add 8 to both sides )

- 4x = - 40 ( divide both sides by - 4 )

x = 10

⇒ AC = 2(3 × 10 - 4) = 2 × 26 = 52

Are you supposed to assume that the function y is linear or that it is quadratic?

                                              576-400
If linear, find the slope:  m = ------------- = 176
                                                 6-5

Then the equation you want is y-400 = 176(x-5), or
                                                 y         = 176x - 880 + 400, or y = 176 - 480.

Suppose the diameter of a circle is \color{green}{6}6start color green, 6, end color green units. What is its circumference?
Marizza181 [45]

Answer:

C =18.84

Step-by-step explanation:

The circumference is given by

C = pi*d

C = 6pi

If we approximate pi by 3.14

C = 6*3.14

C =18.84

The fifth period Coordinate Algebra class received their quiz grades back from Mr. Smith today. The students were offered a chan
sdas [7]
First, we need to put the numbers in order...
58,60,69,71,78,78,85,85,86,87,88,91,93,95,95,95,96,98,100,100
and since there is an even number of numbers (20), we need to find the 2 middle numbers and divide them by 2 to find the median (Q2)
Q2 (the median) = (87 + 88) / 2 = 175/2 = 87.5
now we take all the numbers below 87.5...and find the median (middle number) and that number will be Q1...there is 2 middle numbers...so we add them and divide by 2
Q1 = (78 + 78) / 2 = 156/2 = 78
now we take all the numbers after 87.5....and find the median...there will be 2 numbers, so we add them and divide by 2..that wil be Q3
Q3 = (95 + 95) / 2 = 190/2 = 95

So in summary :
Q1 = 78 <==
Q2 = 87.5 
Q3 = 95 <==

The interquartile range (IQR) is found by subtracting Q1 from Q3.
IQR = 95 - 78 = 17 <==

Find the surface area of the prism or pyramid. Round to the nearest hundredth if necessary.
son4ous [18]

Answer: 345.4

Step-by-step explanation:

SA=2πr^2+2πrh

SA=2(3.14)(5)^2+2(3.14)(5)(6)

SA=2(3.14)(25)+2(3.14)(30)

SA=2(78.5)+2(94.2)

SA=157+188.4

SA=345.4

HELP WITH MY GHGGHH THAKSSS
Charra [1.4K]

Therefore, \frac{8}{7}= 1.14 cannot represent the probability of an event. So, option C is correct.

We need to identify which of the given option cannot represent the probability of an event.

<h3>What is probability?</h3>

The probability of an event occurring is defined by probability. There are many instances in real life where we may need to make predictions about how something will turn out. The outcome of an event may be known to us or unknown to us. When this happens, we say that there is a chance that the event will happen or not.

By simply dividing the favourable number of possibilities by the entire number of possible outcomes, the probability of an occurrence can be determined using the probability formula. Because the favourable number of outcomes can never exceed the entire number of outcomes, the chance of an event occurring might range from 0 to 1.

Now, \frac{1}{14} =0.0714, \frac{8}{7}= 1.14 and \frac{20}{21}=0.952.

Therefore, \frac{8}{7}= 1.14 cannot represent the probability of an event. So, option C is correct.
