Mathematics
1 answer:
spin [16.1K]3 years ago
3 0

Step-by-step explanation:

(0,5) and (-2,-3)

y=mx+b

find m

\frac{y1 - y2}{x1 - x2}  \\   = \frac{5 -  ( - 3)}{0 - ( - 2)}  \\  =  \frac{8}{2}  \\  = 4 \\

m=4

Substitute (0,5) or (-2,-3)

For easy processing substitute : (0,5)

y=4x+b

5=b

y=4x+5 is the answer

  • A) The product of the area model is 3055
  • D) The missing number is 200
  • E) The model shows 47 x 65

=======================================================

Explanation:

The first number along the top is 40, and it multiplies with the second number along the side to get 40 x 5 = 200

You can think of it as 4 x 5 = 20, then you tack on an extra 0 to the '4' and to the '2' as well, so it keeps things balanced.

So this explains how choice D is one of the answers.

-------------------------

After 200 fills in that question mark, we'll have these four numbers inside the table: 2400, 420, 200, and 35

Those four values add up to: 2400+420+200+35 = 3055

This shows that choice A is one of the answers.

--------------------------

Finally, choice E is the third answer because along the top we have 40+7 = 47, and along the side we have 60+5 = 65

Put another way, the total top length is the sum of the two smaller pieces of 40 and 7, which explains how the total top length is 47 units long. A similar argument happens for the left side values as well.

We ultimately have a rectangle that is 47 units across in the horizontal direction, and 65 units tall in the vertical direction.

With your calculator, you should note that 47*65 = 3055 to help confirm everything lines up.

--------------------------

Extra info:

Choice B is false because this contradicts choice D.

Choice C is false because it contradicts choice E

Blizzard [7]

Answer:

The value of the test statistic is -3.14.

Step-by-step explanation:

Test statistic:

t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}

In which X is the sample mean, \mu is the expected value, \sigma is the standard deviation and n is the size of the sample.

A company advertises that its cans of caviar each contain 100 g of their product.

This means that \mu = 100

They calculate a sample mean weight of 99 g and a sample standard deviation of 0.9 g. Sample of 8 cans.

This means that X = 99, \sigma = 0.9, n = 8

So the test statistic will be given by:

t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}

t = \frac{99 - 100}{\frac{0.9}{\sqrt{8}}}

t = -3.14

The value of the test statistic is -3.14.
