You haven't given any options to select.
However, if this is the way of values we can check pythagoras theorem .

5^2 = 25

3^2 + 4^2
9 + 16
25

25 = 25

therefore we can say it is the right angle triangle

How do I solve this??

Liula [17]

2(2p + m) = 3 - 5m

Distributive

4p + 2m = 3 - 5m

2m + 5m = 3 - 4p

7m = 3 - 4p

m = (3 - 4p)/ 7

An airline is planning its staffing needs for the next year. If a new route is approved, it will hire 858 new employees. If a n

stealth61 [152]

Answer:

$E(X) = \sum_{i=1}^n X_i P(X_i)$

And from the problem we know the following:

$P(X_1) = 0.34 , X_1 =858$ represent the condition if the route is approved

$P(X_2) = 1-0.34=0.66 , X_1 =157$ represent the condition if the route is NOT approved

Then replacing in the formula for the expected value we got:

$E(X) = 858*0.34 + 157*0.66 = 395.34$

So then the expected number of new employees to be hired by the airline based on the conditions given is between 395 and 396.

Step-by-step explanation:

For this cae we can define the random variable X who represent the number of new employees to be hired by the airline and we can find the expected value with the following general formula:

$E(X) = \sum_{i=1}^n X_i P(X_i)$

And from the problem we know the following:

$P(X_1) = 0.34 , X_1 =858$ represent the condition if the route is approved

$P(X_2) = 1-0.34=0.66 , X_1 =157$ represent the condition if the route is NOT approved

Then replacing in the formula for the expected value we got:

$E(X) = 858*0.34 + 157*0.66 = 395.34$

So then the expected number of new employees to be hired by the airline based on the conditions given is between 395 and 396.

an organic farm uses 3/7 of the land to grow potatoes and two fifths of the land to grow spinach the remaining land is used to g

melomori [17]

<span>The organic farm uses 3/7 of the land to grow potatoes
=> 2 /5 of the land to grow spinach
=> x = the fraction of the land to grow tomato plants.
The easiest wat to get the answer is convert first the fraction to decimals
=> 3/7 = 0.43
=> 2/5 = 0.4
=> x = ???
=> 0.43 + 0.4 = 0.83
=> let the whole land = 1
=> 1 – 0.83
=> 0.17, the remaining land left for tomato plants
Convert now to fraction
=> 17/100</span> (Approximately)

YOu can also use this method:
=> 3/7+ 2/5 +x = ?
Find the LCM
=> 3/7 + 2/5 = 29/ 35
=> 35/35 - 29 / 35
=> 6 / 35, the remaining land

WHAT IS THE ANSWER FOR 6/7-5/9

pentagon [3]

Well I cannot tell you the answer but here are the steps to answering this question:
1. Subtraction needs to be 2 fractions with the same denominators so the way to do that is to find the factors and pick any that is the same factors for both numbers (it doesn't matter because whatever one you pick, you will get different answers but equivalent fractions which is still correct)
2. subtract only the numerators (the top number) but NOT the denominators (the bottom number) because if you do that, you will get 0 as the denominator and that gives you a negative number and that is a totally wrong answer
3. The sum is your answer!
hope you understood!
Just tell me if you didn't understand and I can tell you in a different way that is easier for you.
