Find z such that 4.8% of the standard normal curve lies to the left of z. (Round your answer to two decimal places)

lukranit [14]

Answer:

The correct answer will be "-1.66".

Step-by-step explanation:

Let z₀ be,

$P(z$

$=0.048$

⇒ $\Phi (z_0)=0.048$

Now,

⇒ $\Phi (-1.6646)=0.048$

$z_0=-1.6646$

$\simeq -1.66$

Thus the above is the right answer.

PLEASEEE HELP!!!!!!! Tim sells two types of pizza. He charges $10 for a cheese pizza and $15 for a pepperoni pizza. Yesterday he

Tanzania [10]

Answer:

$880

Step-by-step explanation:

This is called a system of equations!! Here's how to do it:

1. Make Equations

In this case, the equations would be

p+c=64 (this is saying that pepperoni pizzas plus cheese pizzas equal 64, which we got from the question.)
1/3c=p (this is telling us that he sells 1 pepperonis for 1/3 cheese pizza)

2. Solve the system of equations

For this problem, we will substitute 1/3c for p. The problem becomes

4/3c = 64

Then you divide by 4/3 to get p by itself:

p=48

Now substitute 48 for p in the first equation.

c=16

3. Find the money amounts

Now that you know that pepperoni pizzas equal 48, and cheese equals 16, this is easy.

Multiply 16*10 to get the cheese cost. ($160)
Multiply 15*48 to get the pepperoni cost ($720)
Then add those to get the total!

If the figures shown are congruent, what is the value of x? (Hint: The sum of the three angles of any triangle is 180°.)

professor190 [17]

Answer: THIRD OPTION.

Step-by-step explanation:

For this exercise it is important to remember that, by definition, two triangles are congruent when all their corresponding sides and their corresponding angles are congruent.

Therefore, the size and shape of two congruent triangles are equal.

In this case you know that the triangles shown in the given picture are congruent.

So, based on the explained before, you know that the measure of every corresponding angle of both triangles is the same.

Then, you can conclude that unknown angle "x" has the same measure that the corresponding angle of the other triangle: $38\°$ .

Therefore, you get that the value of "x" is:

$x=38\°$

This matches with the third option.
