If I translated correctly into my native language, then you need to write the equation of the straight line.

y=x this is a straight line through the first and third quarters.

1) multiply by 2: y= 2x

2) to raise the function by 3 units, you need to add 3 to it. For example: y=2x to bring it up: y=2x+3

What is the value of the expression All of 3.9 multiplied by 10 to the power 5 over all of 1.3 multiplied by 10 to the power 2?

Dima020 [189]

So first write out the expression:
$\frac{3.9*10^{5}}{1.3*10^{2}}$
take two 10's from the top to cancel with the two 10's on the bottom.
3.9/1.3 is 3.
The answer is 3*10^3

Liz flips a coin 30 times. The coin lands heads up 21 times and tails up 9 times. Complete each

SSSSS [86.1K]

Answer:

$Pr = 0.50$

Step-by-step explanation:

Given

$n = 30$

$H = 21$

$T = 9$

See attachment for complete question

Required

$P(H)$

The question requires that we calculate the theoretical probability of landing on the head.

This means that, we have to ignore the given data, and we use the following

$S =\{H,T\}$ --- sample space

$n(S) = 2$ --- sample size

$n(H) = 1$ --- occurrence of Head

So, the theoretical probability is:

$Pr = n(H)/n(S)$

$Pr = 1/2$

$Pr = 0.50$

Need help on all these questions!!

Yuki888 [10]

Okay, so YZ = 3 cm. You have XM correct. And YM = 0.5.

Now, you have the midpoint M at the correct spot.

Use Pythagorean's theorem o find the length of AB. a² + b² = c² a=6, b=8.

6² = 36 8² = 64 36 + 64 = 100 AB = 10!

If AB = 10 then AM = 5 MB also = 5

If B is the midpoint of AC, C would be 12 rows down from A, and 16 columns to the right. The last spot where the line intersects.

There are your answers!
