Which of the following scatterplots would have a trend line with a positive slope?

Answers

Answer 1

The correct answer would be the graph at the top left. This would be the correct answer because in order for a slope to be positive the dots must be able to form a line going upwards from the origin point.

d.) A polynomial cannot have a variable in the denominator.

A polynomial consists of constants, variables and exponents. Polynomials are named based on the number of terms they have. Polynomials with 1 term are called monomials. Those with 2 terms are called binomials, and the ones with 3 terms are called trinomials.

Find the zeros of the function f (x) = 4x^2-16

Answers

Answer:

x=-2

x=2

Step-by-step explanation:

We can think of this equation like a statement

"4 times what squared minus sixteen is equal to zero"

First, we need to rearrange the equation:

[tex]4x^2=16[/tex]

Now using our common knowledge, we know that 4 times 4 is equal to 16

now we have another statement:

"x times x is going to be equal to 4"

*Remember that the two numbers have to be the same since x is squared*

Again, we can use common knowledge and say that 2x2 is equal to 4

This means that x=2

Now when you square a variable, the variable can have to values, a positive, and a negative value

So in this case, the other value for x would be x=-2 since -2 squared is also equal to 4

So we can come to a conclusion that

x=2

AND

x=-2

The circumference of a circle is 7.5. What is it’s diameter?

Answers

For ALL circles the circumference (call it ‘C’) is equal to Pi x diameter (call it ‘d’),

so C = Pi x d

But we are told that C = Pi x 7.5

So Pi x d = Pi x 7.5

If we divide both sides of this equation by Pi, we are left with the equation d = 7.5, which is the answer.

ANSWER: The length of the diameter of the circle is 7.5 units of length.

Answer:

175/24

Step-by-step explanation:

First change mixed fraction to improper fraction.

1¾= (1×4+3)/4

= 7/4

4⅙= (4×6+1)/6

= 25/6

now multiply the nominators (numbers on the top) and then the denominators (numbers on the bottom)

I.e

7/4 × 25/6

= 7×25/4×6

= 175/24

it cannot be further simplified so 175/24 is the answer.

Answers

Answer:

40%

Step-by-step explanation:

assuming you actually mean 10^5 and 10^6, to find percentages you do

part/total x percent/100

you have (6x10^5/1.5x10^6) x (x/100)

cross multiply, and you have 6x10^7=1.5x10^6x

divide on both sides by 1.5x10^6

x=40

so the answer is 40%

Sarah has two sets of cards. The first set of 26 cards is labeled with all the letters of the English Language. The second set of 10 cards is numbered 0 through 9.
If Sarah draws one lettered card and one numbered card at random, what is the probability of her drawing a letter in her name and an odd number? (Enter answer as a reduced fraction).

Answers

Answer:

1/13

Step-by-step explanation:

Probability of Sarah drawing a letter in her name

= number of letters in her name: S, A, R and H / total number of letters

= 4/26

Probability of drawing an odd number

= odd numbers / total numbers

= 5/10

Combining the above, Probability of her drawing a letter in her name and an odd number = 4/26 * 5/10

= 1/13

Total Alphabetical cards Sarah has ⇢ 26

Total Letters Sarah's name has ⇢ 4

Probability of getting a card with one of the letter in her name ⇢ 4/26

Total numerical Cards Sarah has ⇢ 10

Total odd numbers in those cards⇢5

Probability of getting a card with an odd number⇢ 5/10

probability of her drawing a letter in her name and an odd number⇢ 4/26 x 5/10 = 1/13

45:60 as its simplest form

Answers

Answer :

3/4.

Explanation

Find the GCD (or HCF) of numerator and denominator

GCD of 45 and 60 is 15

Divide both the numerator and denominator by the GCD

45 ÷ 15

60 ÷ 15

Reduced fraction: 3/4

Therefore, 45/60 simplified to lowest terms is 3/4.

Hi! I hope you are enjoying your day!

In order to simplify this ratio (and 45:60 is a ratio), we should divide both sides of the ratio by 5 (because both 45 and 60 are evenly divisible by 5)

Divide:

9:12

Is the ratio in its simplest form? No.

Why?

Because 9 and 12 can be divided by 3:

3:4

Now the ratio IS in its simplest form.

Hence, the answer is

[tex]\boxed{\boxed{\bold{3:4}}}[/tex]

Hope everything is clear.

Find the area of the missing square off of leg a if the area of one square is 369 and the area of another is 81.

A - 19.2
B - 144
C- 12
D- 288

Answers

Solution:

Note that:

Area of square = s² (s = Side length)

Finding the leg of a square with area of 369 units²

c² = 369=> c = √369 units

Finding the leg of a square with area of 81 units²

b² = 81=> b = √81 = 9 units

Finding side length a using Pythagoras theorem

(√369)² = 9² + a²=> 369 = 81 + a²=> 369 - 81 = a²=> 288 = a²=> a = √288 = √144 x 2 = √12 x 12 x 2 = 12√2 units

Finding the missing area of the square.

Area of square = a²=> Area of square = a² = (a)²=> Area of square = (12√2)²=> Area of square = (12√2)(12√2) = 288 units²

When the three integers 400, 366, and 213 are divided by a positive integer d > 1, the remainders are the same. What is the least possible value of d

Answers

The number d is not a divisor of the integers 400, 366 and 213

The least possible value of d is 17

How to determine the least possible value of d

The numbers are given as:

400, 366 and 213

The divisor is given as: d

Where d > 1

To determine the least possible value of d, we make use of the following Python program, where comments are used to explain each action.

#This iterates from 2 to the smallest number of the three divisors

for d in range(2,213):

#This checks for the common remainder

if(400%d == 366%d) and (400%d == 213%d):

#This prints the value of d, when the smallest remainder of all three integers is determined

print(d)

At the end of the program, the output is 17

Hence, the least possible value of d is 17
