How much higher is 500 than -400 m

Mathematics

Kobotan [32]3 years ago

Answer: 900m

Step-by-step explanation:

think of a line that has negative and positive numbers on it. Go to 0. If you go UP from zero 500m you can add a distance of 500m to it. If you go DOWN 400m that makes the line longer, so you can add those two together. From there it's basic math. 400+500=900. So it's 900m

Answer:

900m

Step-by-step explanation:

So your base is -400m so what you want to do is add up till you get to 0. So you add 400m to get to zero. Then you need to subtract from 500m until you get to 0. So you have 500m. Then you add 400m and 500m (400m+500m) which gives you the answer 900m.

Engineers want to design seats in commercial aircraft so that they are wide enough to fit 9090​% of all males.​ (Accommodating 1
Molodets [167]

Answer:

Hip breadths less than or equal to 16.1 in. includes 90% of the males.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 14.5

Standard Deviation, σ = 1.2

We are given that the distribution of hip breadths is a bell shaped distribution that is a normal distribution.

Formula:

z_{score} = \displaystyle\frac{x-\mu}{\sigma}

We have to find the value of x such that the probability is 0.10.

P(X > x)  

P( X > x) = P( z > \displaystyle\frac{x - 14.5}{1.2})=0.10  

= 1 -P( z \leq \displaystyle\frac{x - 14.5}{1.2})=0.10  

=P( z \leq \displaystyle\frac{x - 14.5}{1.2})=0.90  

Calculation the value from standard normal z table, we have,  

P(z < 1.282) = 0.90

\displaystyle\frac{x - 14.5}{1.2} = 1.282\\x = 16.0384 \approx 16.1  

Hence, hip breadth of 16.1 in. separates the smallest 90​% from the largest 10%.

That is hip breaths greater than 16.1 in. lies in the larger 10%.

What is the solution of -4(8-3x)&gt;or=6x-8?
Illusion [34]

Answer:

-4(8-3x)>or =6x-8

Step-by-step explanation:

open d bracket

-32+12x >or = 6x-8

collect like terms

12x-6x >or =-8+32

6x = 24

divide both sides by 6

x= 4

Use a table to find two consecutive integers between which the solution lies.
jolli1 [7]

Answer:

  -5 and -4

Step-by-step explanation:

It is far easier just to solve the equation than to determine appropriate integer bounds on the solution.

In the attachment, we show a couple of initial trials at solutions. The nearness of y=5 to being correct suggests that the next higher integer may be helpful, too. It is.

We find -4 and -5 to bracket the solution.

_____

The actual solution is (3.4 -1.3)/-0.5 = -4.2.
