Emma needs 2 pounds of ground meat to make a meatloaf. She goes to Brodies and finds one package of meatloaf with 2.56 pounds and another package with 2.09 pounds. She uses rounding to the nearest whole. Which package should she choose to get closer to 2 pounds? Explain.
Answer:
package with 2.09 pounds
Step-by-step explanation:
When rounding to the nearest whole number, if the first number after the decimal point is equal or greater than 5, add 1 to the number before the decimal. If this is not the case, add 0 to the number before the decimal point.
to round 2.56 to the nearest whole number equals 3.
While to round 2.09 to the nearest whole number equals 2.
Because Emma needs 2 pounds, she would go with 2.09 pounds

Using ƒ(x) = 3x − 3 and g(x) = -x, find g(ƒ(x)).
Answer:
We conclude that:
g(f(x)) = -3x+3
Step-by-step explanation:
Given
f(x) = 3x-3g(x) = -xTo determine
g(f(x)) = ?In order to determine g(f(x)), first we need to substiute f(x) = 3x-3 in g(f(x)).
g(f(x)) = g(3x-3)
now substitute x = 3x-3 in g(x)
= -(3x-3)
= -3x+3
Therefore, we conclude that:
g(f(x)) = -3x+3
Step by step explanation
Answer: x = 4
Step-by-step explanation:
x/2=10/5
Multiply both sides of the equation by 2.
2⋅ x/2 = 10 /5 ⋅ 2
Simplify both sides of the equation.
Cancel the common factor of 2.
Rewrite the expression.
x= 2 ⋅ 10/5
Divide 10 by 5.
x= 2 ⋅ 10/5
Multiply 2 by 2.
x = 2 ⋅ 2
x = 4

Parallel lines always have equal slopes. Therefore, this eliminates two options and we just need to find the y-intercept. Since the line passes through [tex](-4,-2)[/tex], we have:
[tex]-2=\frac{1}{4}(-4)+b,\\b=-1[/tex].
Therefore, the equation of the line is:

yler bought snacks for his team's practice. He bought a bag of oranges for $1.94 and a 24-pack of juice bottles. The total cost before tax was $43.22. Write and solve an equation which can be used to determine x, how much each bottle of juice costs?
Answer:
1.94 + 24x = 43.22 ;
1.72
Step-by-step explanation:
Given :
Cost of orange = 1.94
Pack of juice = 24
Total amount spent = 43.22
Cost of orange + (number of juice * cost per bottle) = total amount spent
Let cost per bottle = x
1.94 + (24 * x) = 43.22
1.94 + 24x = 43.22
24x = 43.22 - 1.94
24x = 41.28
x = 41. 28 / 24
x = 1.72
A die is rolled 25 times and 12 evens are observed. Calculate and interpret a 95% confidence interval to estimate the true proportion of evens rolled on a die.
Answer:
The 95% confidence interval to estimate the true proportion of evens rolled on a die is (0.2842, 0.6758). This means that we are 95% sure that for the entire population of dies, the true proportion of evens rolled on a die is between 0.2842 and 0.6758
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
For this problem, we have that:
[tex]n = 25, \pi = \frac{12}{25} = 0.48[/tex]
95% confidence level
So [tex]\alpha = 0.05[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].
The lower limit of this interval is:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.48 - 1.96\sqrt{\frac{0.48*0.52}{25}} = 0.2842[/tex]
The upper limit of this interval is:
[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.48 + 1.96\sqrt{\frac{0.48*0.52}{25}} = 0.6758[/tex]
The 95% confidence interval to estimate the true proportion of evens rolled on a die is (0.2842, 0.6758). This means that we are 95% sure that for the entire population of dies, the true proportion of evens rolled on a die is between 0.2842 and 0.6758

What is the distance from C to D?
A. 5 units
B. 1 unit
C. 25 units
D. 7 units
Answer:
Option A
Step-by-step explanation:
According to the distance formula , for any 2 points P & Q whose coordinates are (x¹ , y¹) and (x² , y²) respectively. So ,
[tex]PQ = \sqrt{(x^{2} - x^{1} )^{2} + (y^{2} - y^{1})^{2} }[/tex]
NOTE = HERE x² , y² DOESN'T MEAN THE SQUARES OF x & y . THEY ARE JUST COORDINATES.
According to the question ,
Coordinate of C = (2 , -1)
Coordinate of D = (5 , 3)
Using distance formula ,
[tex]CD = \sqrt{(5-2)^{2} + (3 -(-1))^{2} }[/tex]
[tex]=> CD = \sqrt{3^{2} + 4^{2} } = \sqrt{9 + 16} = \sqrt{25} = 5[/tex]

While attempting to multiply the expression (2-5i)(5+2i) a student made a mistake.
(2-5i)(5+2i)= 10+4i -25i - 10i^2
=10+4(-1)-25(-1) - 10(1)
=10-4+25-10
=21
What is the error?
Answer:
The left side of the equation is ignored
i is treated as -1, which it is not, it is instead the square root of negative 1.
To solve it properly we get:
(2 - 5i)(5 + 2i)
= 10 + 4i - 25i - 10i²
= 10 + 21i + 10
= 20 - 21i
Answer:
The error is that, the student replaced i with -1 which is wrong as i = √-1
And he has replaced i^2 with 1 while i^2 = -1
Step-by-step explanation:
Given two numbers that are being multiplied are:
(2-5i)(5+2i)
We will solve the question to get the right result so that the error can be detected.
So, multiplying both
[tex]= 2(5+2i)-5i(5+2i)\\=10+4i-25i-10i^2\\=10-21i-10(-1)\ \ \ as\ i^2 = -1\\=10-21i+10[/tex]
The error is that, the student replaced i with -1 which is wrong as i = √-1
And he has replaced i^2 with 1 while i^2 = -1

The volume of a cylinder is 176 cm and its height is 11 cm,
What is the length of the cylinder's radius?
Answer:
4cm
Step-by-step explanation:
The volume of the cylinder is the product of the area of the base and the height. In mathematical equation, this can be written as,
V = πr²h

What is the volume of this rectangular prism? 16 cubic centimeters 96 cubic centimeters 160 cubic centimeters 192 cubic centimeters a rectangular prism that is 2 centimeters by 8 centimeters by 6 centimeters I NEED HELP NOW
Answer: 96 cubic centimeters
Step-by-step explanation:
For a cubic prism with length L, width W and height H, the volume is:
V = L*W*H
For this case, we know that the measures of the prism are:
2cm, 8cm, and 6cm, then we can take:
Length = 2cm
Width = 8cm
Height = 6cm
Then the volume of this prism will be:
V = 2cm*8cm*6cm = 96 cm^3
Then the correct option is 96 cubic centimeters
