A number to be a rational number that is not an integer but a while number
Answer:
So coming back to the question; No, there is no rational number that is not an integer but is a whole number. The number is called as a rational number if it can be expressed as p/q where p & q are integers & q is not 0. All negative integers are rational numbers but those are not whole numbers.Jan 1, 2020

Find the discriminate, number of roots and solve the quadratic equation using the quadratic formula -my answers are pribably wrong
Answers:
discriminant = dnumber of roots = esolutions = g=================================================
Explanation:
Let's compute the discriminant. Here we have a = 1, b = 1, c = -2
d = b^2 - 4ac
d = 1^2 - 4(1)(-2)
d = 9
The fact that d > 0 tells us we have two different real number solutions.
------------------------
We can use the quadratic formula to solve, or we can factor. I'll use the factor method.
x^2 + x - 2 = 0
(x - 1)(x + 2) = 0
x-1 = 0 or x+2 = 0
x = 1 or x = -2
The two solutions are -2 and 1
I’ll make you as brainliest do these to problems show ya work !
Answer:
1. 7
2. 13
Step-by-step explanation:
1. x = 2 and y = 3
y^2 - x
= 3^2 - 2
= 9 - 2
= 7
2. x = 5 and z = 4
z + x + z
= 4 + 5 + 4
= 9 + 4
= 13
Answer:
7 for the first question and 13 for the second one
The annual profits for a company are given in the following table, where x represents
the number of years since 1997, and y represents the profit in thousands of dollars.
Write the linear regression equation that represents this set of data, rounding all
coefficients to the nearest tenth. Using this equation, find the projected profit (in
thousands of dollars) for 2008, rounded to the nearest thousand dollars.

A golfer observed that 2 out of every 3 balls she hit landed near the hole. If she hits 72 shots, approximately how many times will her ball land near the hole?
9514 1404 393
Answer:
48
Step-by-step explanation:
About 2/3 of her 72 shots will land near the hole.
2/3 × 72 = 48
Her ball will land near the hole approximately 48 times.

Stephanie is painting her room wich is 14' long by 9' wide and each wall is 10' tall. How many square feet of paint will she use? help.
Answer:
460 sq ft
Step-by-step explanation:
Assuming the room is a perfect rectangle and not accounting for doors and windows:
14 ft x 10 ft = 140 sq ft X 2 = 280 sq ft
9 ft x 10 ft = 90 sq ft x 2 = 180 sq ft
280 sq ft + 180 sq ft = 460 sq ft
determine the second derivative evaluated at t=0
If
[tex]M(t) = e^{3(e^t-1)}[/tex]
then using the chain rule, we have
[tex]M'(t) = e^{3(e^t-1)} \times 3e^t = 3e^{3(e^t-1)+t}[/tex]
[tex]M''(t) = 3e^{3(e^t-1)+t} \times (3e^t+1)[/tex]
Then
[tex]M''(0) = 3e^{3(e^0-1)+0} \times (3e^0+1) = 3e^0 \times (3+1) = \boxed{12}[/tex]

Answer:
37, 60, 30Step-by-step explanation:
Ann - a, Josh - j, Claire - c
a = j + 7j = 2ca + j + c = 157Substitute a and j into last equation and solve for c:
(j + 7) + 2c + c = 1572c + 7 + 3c = 1575c = 150c = 30Find a and j:
a = 30 + 7 = 37j = *30 = 60find the mean of 31.6, 34.5, 29.8, 12,1
Answer:
27
Step-by-step explanation:
To figure out the mean of a group of numbers, one must add the numbers together and divide by the number of terms.
31.6 + 34.5 + 29.8 + 12.1 = 108
There are four terms in the group of numbers.
108 / 4 = 27
Therefore, the mean is 27.

What is the correct expansion for (x+8)^2
Answer:
Answer: x² + 16x + 64
Step-by-step explanation:
[tex] {(x + 8)}^{2} [/tex]
double the brackets, to remove the power:
[tex] = (x + 8)(x + 8)[/tex]
open the brackets:
Generally:
[tex]{ \boxed{(a + b)(a + b) = {a}^{2} + 2ab + {b}^{2} }}[/tex]
from our equation given;
a » x
b » 8
substitute in the equation in the box:
[tex](x + 8)(x + 8) = {x}^{2} + \{ 2(x)(8) \} + {(8 )}^{2} \\ \\ = {x}^{2} + 16x + 64[/tex]
Answer:
x² + 16x + 64

plzz someones help me plz I will mark brainlest diameter is 1 3/4
Answer:
The area of the circle is 2.41 in^2
Step-by-step explanation:
You are given the diameter, 1 3/4. This is a mixed fraction, so let's convert that into decimal.
1 3/4 = 7/4
7/4 = 1.74
Now, let's use the area of circle formula.
A = 1/4πd^2
A = 1/4 * π * 1.75^2
A ≈ 2.40528
Let's round the area to the nearest hundredth.
2.40528 = 2.41
Nick and Monica are paid $41.25 for their work. Nick worked 2.5 hours, and Monica worked 3 hours. They split the money according to the amount of time each of them worked.
Nick and Monica are paid $(Blank) for each hour worked. Nick's share of the money is $(Blank)
Answer:
BRIANLIEST PLZ
N = 18.75
M = 22.5
Step-by-step explanation:
Need the ratio of money paid to each. We know how the ratio of time is divided so we can use this ratio to find the amount paid.
T = t1 + t2 = 2.5 + 3 = 5.5
r1 =2.5/5.5
r2 = 3/5.5
Nick = r1 * 41.25 = 18.75
Monica = r2 * 41.25 = 22.5

-3(6b + 4) = 2(-5b+10)
b=
Answer:
b = -4
Step-by-step explanation:
-3(6b + 4) = 2(-5b + 10)
-18b - 12 = -10b + 20
(-18b + 10b) - 12 = (-10b + 10b) + 20
-8b - 12 = 20
-8b (- 12 + 12) = 20 + 12
-8b = 32
-8b/-8 = 32/-8
b = -4
