Answers

[tex]\mathfrak{\huge{\pink{\underline{\underline{AnSwEr:-}}}}}[/tex]

Actually Welcome to the Concept of the Linear Algebra

a-2= 3+6a/3

=> 3(a-2)= 3+6a

=> 3a-6= 3+6a

=> -6-3=6a-3a

=> -9=3a

hence, a=-3

Question 5 of 8 -
Eureka Math G5 EOMI Assessment (2020-2021)
Which choice is a reasonable product for the expression 8 x 2.48 ?
O 1.984
19.84
198.4
0 1984
Explain why your choice is correct using words and numbers.

Answers

Answer:

8 x 2.48 = 19.84

Step-by-step explanation:

We need to find the product for the expression 8 x 2.48.

First no is 8 and second no is 2.48

Product means to multiply.

We can write 2.48 as [tex]\dfrac{248}{100}[/tex]

i.e.

[tex]8\times \dfrac{248}{100}\\\\=\dfrac{1984}{100}[/tex]

Now, apply decimal after 9. So,

8 x 2.48 = 19.84

Hence, the correct option is (b).

The actual volumes of quart-size jars of Hellmann's mayonnaise are uniformly distributed from 31.58 to 32.51 fluid ounces. Find the standard deviation in volumes of quart-size Hellmann's mayonnaise jars (in fluid ounces). NOTE: There are 32 fluid ounces in a quart.

Answers

Answer:

0.27

Step-by-step explanation:

The standard deviation of a uniform distribution is:

σ² = (b − a)² / 12

σ² = (32.51 − 31.58)² / 12

σ² = 0.0721

σ = 0.268

Rounded to the hundredths place, the standard deviation is 0.27.

To solve this question, we use concepts of the uniform probability distribution.

Using this, we get that the standard deviation in volumes of quart-size Hellmann's mayonnaise jars is of 0.2685 fluid ounces.

Uniform probability distribution:

An uniform distribution has two bounds, a and b.

The standard deviation is:

[tex]S = \sqrt{\frac{(b-a)^2}{12}}[/tex]

The actual volumes of quart-size jars of Hellmann's mayonnaise are uniformly distributed from 31.58 to 32.51 fluid ounces.

This means that [tex]a = 31.58, b = 32.51[/tex]

Find the standard deviation in volumes of quart-size Hellmann's mayonnaise jars (in fluid ounces).

[tex]S = \sqrt{\frac{(32.51 - 31.58)^2}{12}} = 0.2685[/tex]

Thus, the standard deviation is of 0.2685 fluid ounces.

The record low temperature in Pittsburgh, PA is ​-22°F. The record high is 103°F. What is the difference in the record high and the record low temperatures?

Answers

Answer:

The difference in the record high and the record low temperatures is 125°F

Step-by-step explanation:

Given a quantity T that varies in time, say T1 and T2, being T1 the initial value and T2 the final value.

The change or difference between the final and the initial values is:

T=T2-T1

The record low temperature in Pittsburgh, PA is T1=-22°F while its record high is T2=103°F

The difference is:

T=103°F - (-22°F)

Note both negative signs multiply to produce a positive sign, and a sum instead of a subtraction:

T=103°F + 22°F = 125°F

The difference in the record high and the record low temperatures is 125°F

Step-by-step explanation:

we have the equations:

6j + n/3 = 134

j/3 + n = 31

54j + 3n = 1206

j + 3n = 93

53j = 1113

j = 21

What is the point-slope form of the equation of the line?

Answers

Answer:

y-y1 = m (x-x1)

where

m is the slope

and (x1,y1) is one of the points given.

You have been given 2 points (-12,8) and (9,1). You can call one of them (x1,y1) and the other (x2,y2). It doesn't matter which one is which.

But before we go further, we need to determine the slope.

We can do this from the points as well.

y2-y1

m = ---------

x2-x1

Let's say

(x1,y1) = (-12,8)

(x2,y2) = (9,1)

This gives us a slope of

y2-y1 1-8 -7 -1

m = --------- = ---------- = ---- = ---

x2-x1 9-(-12) 21 3

Now that we have everything we need

y-8 = (-1/3)[x-(-12)]

Distribute the -1/3

y-8 = (-1/3)x -4

If we add 8 to both sides we have the equation in the slope intercept form (y=mx+b)

y = (-1/3)x + 4

The local monsters are currently throwing a bash
known as the Monster Mash. At the beginning of the
party, there were 5 monsters attending. At the end
of the party there were 225 monsters. If an average
4 monsters came to the bash every minute of the
party, how long did this Graveyard Smash last?

Answers

Answer: 55 minutes

Step-by-step explanation:

First, you would have to subtract 5 from 225 because there are already 5 monsters there.

225-5= 220

Next, you would have to divide 220 by 4 to find the amount of minutes.

220/4= 55

1.80 + 3.72 (0.25 x b) = 13.02

Step-by-step explanation:

First, combine the "one-time" costs (the medium pendant and the medium chain)

1.80 + 3.72 = 5.52

Now, multiply the cost of the beads by the amount of beads you want

0.25 x 30 = 7.50

Now combine both costs to get the total cost

5.52 + 7.50 = 13.02

It would cost Tamara $13.02 to make a medium length necklace
