you start driving east with 14 miles turn left and Drive North for another 10 miles at the end of driving what is your straight
Zigmanuir [339]

Answer:

17.205 miles

Step-by-step explanation:

Since these directions form a 90-degree angle, we can use the Pythagorean Theorem.

14^2 + 10^2 = c^2

196 + 100 = c^2

296 = c^2

It doesn't have a perfect square root, you can either say that it is \sqrt{296} or approximately 17.205 miles.

-11 - 5a = 6(5a+4) ?? Totally having a brain fart
lions [1.4K]
-11-5a=6(5a+4) .... Distribute the 6 to 5a and 4
-11-5a=30a+24 .... Subtract 30a from both sides
-11-5a-30a=24  .... Add 11 from both sides
-5a-30a=24+11 .... Add like terms
-35a=35            .... Divide -35a from both sides
a=-1                  .... Final answer

Laboratory tests show that the lives of
SIZIF [17.4K]
<h3>Answer:  34%</h3>

This result is approximate.

=========================================================

Explanation:

mu = 750 = mean

sigma = 75 = standard deviation

The raw scores or x values are x = 750 and x = 825

Let's compute the z score for each x value

z = (x - mu)/sigma

z = (750 - 750)/75

z = 0

and

z = (x - mu)/sigma

z = (825 - 750)/75

z = 1

Therefore P(750 ≤ x ≤ 825) is equivalent to P(0 ≤ z ≤ 1) in this context.

Use a z score table to determine that

P(z ≤ 0) = 0.5

P(z ≤ 1) = 0.84314 approximately

So,

P(a ≤ z ≤ b) = P(z ≤ b) - P(z ≤ a)

P(0 ≤ z ≤ 1) = P(z ≤ 1) - P(z ≤ 0)

P(0 ≤ z ≤ 1) = 0.84314 - 0.5

P(0 ≤ z ≤ 1) = 0.34314 approximately

The value 0.34314 then converts to 34.314% which rounds to <u>34%</u>

Or you could use the empirical rule as shown below. The pink section on the right is marked <u>34%</u> which is approximate. This pink section is between z = 0 and z = 1.

In parallelogram LMNO, LM = 4.12, MN = 4, LN = 5, and OM = 6.4. Diagonals and intersect at point R. What is the length of ?
timofeeve [1]

Answer:

The length of OR = 3.12

Step-by-step explanation:

In a parallelogram:

LM = 4.12

MN = 4

LN = 5 = 2.5 (divided by 2)

OM = 6.4

where LN and OM are diagonals. We will find the length of OR.

Now by applying the Pythagorean theorem:

b = √c²-a²

OR= √(4)²-(2.5)²

OR = √16-6.25

OR = √9.75

OR = 3.12

Thus the length of OR = 3.12 ...
