The perimeter of an iPad Air is 820 mm. Its length is 100 mm less than twice the
width.
If x = the length of the iPad Air and y = the width of the iPad Air, the linear system of

2x + 2y = a
bx = cy-d
The value of a is:
A The value of b is:
A The value of c is:
Ą The value of d is:
1

Answers

Answer:

a = 820, b = 1, c = 2, d = 100

Step-by-step explanation:

Let x represent the length of the iPad Air and y represent the width of the iPad Air. Since the perimeter of an iPad Air is 820 mm, hence:

2(length + breadth) = 820

2(x + y) = 820

2x + 2y = 820               (1)

Also, the length is 100 mm less than twice the  width. Therefore:

x = 2y - 100               (2)

Given that the equations be used to model this situations is:

2x + 2y = a

bx = cy-d

Therefore comparing this model with equation 1 and 2, we get that:

a = 820, b = 1, c = 2, d = 100

y = -4/3 x is the answer...

which is the same as y = - 1 1/3 x

you don't have that choice, "A" and "C" are the same..

Answers

Answer:

Step-by-step explanation:

Remark

The method you would use is

find the area of the rectanglefind the area of the left trianglefind the area of the right triangleSubtract the two triangle's areas from the area of the rectangle.

Area of the rectangle

Area = L * W

L = 3 + 14 =  17

W = 6

Area = 6 * 17 =                                       102

Area of Left triangle

H = 6

B = 3

Area = 1/2 * B * H

Area = 1/2 * 3 * 6

Area =                                                    9

Area of the triangle on the right

H = 6

B = 17 - 7 = 10

Area = 1/2 * b * h

Area = 1/2 * 6 * 10 =                             30

Area of the two triangles =                39

Area of the green area = 102 - 39 = 63

since y=2/5x-3 we substitute x=10 in making it y=2/5*10-3

following PAMDAS we do multiplication first so 2/5*10=4.

so y=4-3 and then we subtract and get y=1. Hope this helps:> if you need more explanation message me. If not give this a heart for helping. Good luck.

(There's no angles shown so it can't be the second option.)

The diagram has lines on the sides, if it we're SAS then the triangle would have an angle.

Answer:

ΔABC≅ΔDEF by SSS Postulate

Step-by-step explanation:

Hi there!

We are given 2 triangles

And we want to prove them congruent

You may notice that AC and FD have the same tick markings, AB and ED have the same tick markings, and CB and FE have the same tick markings

This means that those sides are congruent

In other words,

AC≅FD

AB≅DE

CB≅FE

If we have 3 pairs of congruent sides, that is enough for one concurrency postulate called side-side-side (SSS), which states that if 3 sides of a triangle are congruent to 3 sides in another triangle, then those triangles are congruent

So the triangles are congruent, but we need to put their vertices in the correct order

So if we make the name of the first triangle ABC, then we need to find the corresponding vertices in the second triangle

So let's find those vertices

D is corresponding to A, as they are both in between line segments that have 1 and 2 tick markings on them

E is corresponding to B, as they are both between line segments that have 2 and 3 tick markings on them

And finally, F is corresponding to C, as they are both between line segments that have 1 and 3 tick markings on them

So the name of the second triangle is DEF

ΔABC≅ΔDEF by SSS Posulate

Suppose a normal distribution has a mean of 98 and a standard deviation of 6. What is P(x < 104)?
A. 0.16
B. 0.975
C. 0.84
D. 0.025

Answers

Answer:

Step-by-step explanation:

If the mean is 98, then 104 is only standard deviation away. If we are looking for the values less than this, we have the areas under the normal curve of 34%, 34%, 13.5%, 2.35%, .15% which add to 84%, or as a decimal, .84, choice C.

The z-score of the normal distribution P ( x ≤ 104 ) = 0.84

What is a z-score?

The relationship between a value and the mean of a set of values is expressed numerically by a Z-score. The Z-score is computed using the standard deviations from the mean. A Z-score of zero indicates that the data point's score and the mean score are identical.

The Z-score is calculated using the formula:

z = (x - μ)/σ

where z: standard score

x: observed value

μ: mean of the sample

σ: standard deviation of the sample

Given data ,

Let the z-score of the distribution be z

And , the mean be μ = 98

And , the standard deviation be σ = 6

where z = (x - μ)/σ

So , P ( x ≤ 104 ) = [ P ( x - 98/6 ) ≤ 104 - 98 / 6 ) ]

On further simplification , we get

P ( x ≤ 104 ) = P ( x ≤ 1 )

Using a standard normal distribution table or calculator, we can find that the probability of a z-score less than 1 is approximately 0.8413. Therefore, the probability of x being less than 104 is approximately:

P(x < 104) = P(z < 1) ≈ 0.8413

So there is approximately an 84.13% chance that a value selected at random from this normal distribution will be less than 104

Hence , the probability is 0.84
