Solve the problems using systems of equations.

maw [93]2 years ago
5 0

Step-by-step explanation:

Let the two numbers be x and y

x+y =5 ---1

x-y =-3 ---2

Rearrange equation 1

x =5-y

Substitute x in the second equation

(5-y)-y =-3

5-y-y =-3

5-2y =-3

Collect like terms

5+3 = 2y

8 = 2y

Divide both sides by the coefficient of y (2)

8/2 = 2y/2

4 = y

y= 4

Substitute y in equation 1

x+4 =5

Subtract 4 from both sides

x+4-4 = 5-4

x+0 = 1

x= 1

The two numbers are 1 and 4

In the Country A legal system, a defendant is presumed innocent until proven guilty. Consider a nullhypothesis, H0, that the def
Pie

Using error concepts, it is found that in this problem, a type I error would be finding an innocent person guilty, while a type II error would be finding a guilty person innocent.

<h3>What are Type I and Type II errors?</h3>
  • Type I: Rejection of a true null hypothesis. The null hypothesis is true, but from a sample, you get enough evidence to reject.
  • Type II: Non-rejection of a false null hypothesis. The null hypothesis is false, but from a sample, you do not get enough evidence to reject.

Hence:

In this problem, a type I error would be finding an innocent person guilty, while a type II error would be finding a guilty person innocent.

A pie was cut into 8 slices equally. If Ruben ate 3/4 of the pie , how many slices did he eat?
Ann [662]
He ate 6 slices. There are two methods of doing this, you can multiply the numerator and denominator by 2: \frac{3}{4} • 2 = \frac{6}{8}. Or you can multiply 8 by \frac{3}{4} = 6. It means he ate 6 slices out of the 8 slices.

Find the value of x.
omeli [17]

Answer:

The value of x is 4√5 ⇒ 1st answer

Step-by-step explanation:

* Lets revise the rules in the right angle triangle when we draw the

 perpendicular from the right angle to the hypotenuse

- In triangle ABC

# Angle B is a right angle

# The hypotenuse is AC

# BD ⊥ AC

∴ (AB)² = AD × AC

∴ (BC)² = CD × AC

∴ (BD)² = AD × CD

∴ BD × AC = AB × BC

* Lets use one of these rules to solve the problem

- y is the perpendicular from the right angle to the hypotenuse

- x is one leg of the right angle

∵ The length of the hypotenuse = 5 + 11 = 16 units

∵ The part nearest to x = 5

* Lets use the rule (AB)² = AD × AC

∴ x² = 5 × 16 = 80 ⇒ take √ for both sides

∴ x = √80 = 4√5 units
