Determine the area under the standard normal curve that lies to the right of the z-score 0.48 and to the left of the z-score 0.7
pychu [463]

Answer:

The area lies to the right of the z-score 0.48 means all the values greater than it. This can be calculated on a graphing calculator using the function normCdf, where

  • Lower bound = 0.48
  • Upper bound = 9999
  • Mean = 0
  • Standard deviation = 1

<u>The result would be normCdf(0.48,9999,0,1) ≈ </u><u>0.315614</u>

<u />

The area lies to the left of the z-score 0.79 means all the values less than it. This can be calculated on a graphing calculator using the function normCdf, where

  • Lower bound = -9999
  • Upper bound = 0.79
  • Mean = 0
  • Standard deviation = 1

<u>The result would be normCdf(-9999,0.79,0,1) ≈</u><u> 0.785236</u>

Explain in 1-2 paragraphs how design and problem solving are related. provide an example of a problem situation in which design
luda_lava [24]
When comparing and contrasting, it's always good to think about what your doing it with.
I'm not going to give to a full paragraph, but I'd love to help get one started for you!

First, let's look at the definition of both terms:

-Design: "<span>purpose, planning, or intention that exists or is thought to exist behind an action, fact, or material object" ~ Google

-Problem Solving: "Taking different approaches to finding a solution to the problem, or task at hand."

Now, let's compare. When designing things, you in a way, are problem solving to figure out how to create or build a solution to a problem. This can be through trial and error, or complex thinking.

I hope this helps, and good luck! :)</span>

HELP HELP ME PLZ !!!
nikklg [1K]

Answer:

GK=JK

Step-by-step explanation:

SSS congruency  is side-side-side congruency. We are given that GH=JH and KH=KH, which are both sides.

For SSS, we need 3 pairs of congruent sides. We already have 2 pairs.

The options are:

<G=<J

<H=<H

GK=JK

the first two options, <G=<J and <H=<H are talking about congruent angles. We don't need to know about congruent angles for SSS

GK=JK is talking about a pair of congurent sides. Then, we would have 3 pairs of congruent sides, satisfying the criteria needed for SSS. Therefore, we must know that GK=JK.

Hope this helps!

maurice has 54 fewer comic books than rebecca.they have 130 comic books together .How many comic books are in maurices collectio
eduard
Answer

Rebecca has 76 comic books
Maurice has 54 comic books

Step-by-step

Since there are 54 fewer comics and together they have 130 comics, you should subtract 54 from 130. Once you do that your answer will be 76; and that is how many comics Rebecca has. And 76+54=130 so Maurice has 54 comics
