at food mart, hot dogs can be purchased in packages of 8 for $2.40 or packages of 12 for $3.00. which is a better buy? explain how you know HELP
Answer:
12-hot dog package is better buy because the per hot dog price is 5 cents cheaper
Step-by-step explanation:
2.40/8 = 0.30 per hot dog
3.00/12 = 0.25 per hot dog (this is the better buy by $.05)
Answer:
12-hot dog package per hot dog price is 5 cents cheaper
Step-by-step explanation:
= 2.40/8 = 0.30 per hot dog
= 3.00/12 = 0.25 per hot dog (this is the better buy by $.05)

If I had 36 apples what is the percentage of 20
Answer:
20 apples is 55.55% of 36 apples.
Step-by-step explanation:
Given that I had 36 apples, to determine what is the percentage of 20 of them, the following calculation must be performed:
36 = 100
20 = X
(20 x 100) / 36 = X
2000/36 = X
55.55 = X
Therefore, 20 apples is 55.55% of 36 apples.
which of the following is not a solution of -2 is less than or equal to x less than 5
Answer:
See Explanation
Step-by-step explanation:
Given
[tex]-2 \le x < 5[/tex]
Required
Which is not a solution
The options are not given. So, I will list out the solutions, instead.
We have:
[tex]-2 \le x < 5[/tex]
This implies that: x starts from -2 and ends at 4
[tex]x = \{-2,-1,0,1,2,3,4\}[/tex]
Any number outside the above is not a solution of [tex]-2 \le x < 5[/tex]

Listed below are amounts of arsenic in samples of brown rice from three different states. The amounts are in micrograms of arsenic and all samples have the same serving size. The data are from the Food and Drug Administration. Use a 0.05 significance level to test the claim that the three samples are from populations with the same mean. Assume that the distributions for each state are normal and that all variances are equal.

Answer:
Texas Texas Texas is I think right
No, the claim that the three samples are from populations with the same mean is not correct and this can be determined by using the given data.
Given :
The amounts are in micrograms of arsenic and all samples have the same serving size. The data are from the Food and Drug Administration. Use a 0.05 significance level.The Hypothesis test is given below:
Null Hypothesis: [tex]H_0:\mu_1=\mu_2=\mu_3[/tex]
Alternative Hypothesis: [tex]H_a:\mu_1\neq \mu_2\neq \mu_3[/tex]
For the F-test, the test statistics is given by:
[tex]F = \dfrac{MS_{\rm{between}}}{MS_{\rm{within}}}[/tex]
Now, substitute the values of known terms in the above expression.
[tex]F = \dfrac{15.8252}{0.6896}[/tex]
[tex]F = 22.95[/tex]
So, the p-value regarding the value of F is:
[tex]P-value=P(F>22.95)[/tex]
[tex]P-value = 1.0.9999[/tex]
[tex]P-value = 0.0001[/tex]
The Null Hypothesis is rejected because P-value is less than the significance value.

Use the graph to find the approximate solutions to the question.
What is the distance between (-9, -6) and (-2,-2)?
Choose 1 answer:
I NEED HELP I DONT UNDERSTAND!!
Answer:
Step-by-step explanation:
there is a formula for finding distance,
distance = sqrt [ ( x2-x1)^2 + (y2-y1)^2 ]
where point P1 = (-9.-6)
in the form of (x1,y1)
and point P2 = (-2,-2)
in the form of (x2,y2)
then
distance = sqrt [ (-2-(-9))^2 + (-2-(-6))^2 ]
distance = sqrt [ (-2+9)^2 + (-2+6)^2 ]
distance = sqrt [ [tex]7^{2}[/tex] + [tex]4^{2}[/tex] ]
distance = [tex]\sqrt{65}[/tex]
you can leave it in the form of [tex]\sqrt{65}[/tex] because that's the most accurate , but also can make a close approximation with 8.062257748

point a is at (-7 5) and point c is at (5 -1). find the coordinates of point b on line ab such that ab is 5 times as long as bc
Step-by-step explanation:
Let the coordinates of point b be (x,y).
Given the coordinates of a (-7,5) and c(5,-1)
Now according to question
ab = 5bc
using distance formula
[tex]\sqrt{(x+7)^2+(y-5)^2} =5\sqrt{(5-x)^2+(-1-y)^2}[/tex]
Solving we can get
[tex]x=-\frac{-11+\sqrt{-4y^2-10y+25}}{2},\:x=\frac{\sqrt{-4y^2-10y+25}+11}{2}[/tex]'
However, we do need either x or y coordinate of point b to find the other.

4 1/2 divied 1 5/8 please help
Answer:
36/13 (2 10/13)
Step-by-step explanation:
Convert 4 1/2 into an improper fraction: 4 1/2 = 9/2
Convert 1 5/8 to an improper fraction : 1 5/8 = 13/8
Divide: Dividing 2 fractions is the same as multiplying the first fraction by the reciprocal of the second value (the numerator becomes the denominator and the denominator becomes the numerator). 13/8 is 8/13 as a reciprocal. Next multiply the 2 numerators. 9 x 8 = 72. Then multiply the denominators. 2 x 13 = 26. Which gives 72/26. Divide both numbers by 2 which gives 36/13. 36/13 as a mixed number is 2 10/13

B Reading Choose the best estimate for the multiplication problem below. 85 x 86
A. 8100
B. 10,400
C. 12,200
Answer:
A. 8100
Step-by-step explanation:
85 x 86
To estimate, we multiply 85*100, which is the easiest multiplication, as a multiplication by 100 is the same as placing two zeros at the end of the number.
85*100 = 8500
Since 86 < 100, 85*86 < 8500. Thus, the correct estimate is given by option A.
What is the range of possible sizes for side x?
Answer:
x = 3.96
Step-by-step explanation:
To find the missing side length you'll need the formula a^2 + b^2 = c^2
a and b would be the shorter ends, 2.8 and 2.8
c would be the longer end that's opposite the right angle.
so substitute values
2.8^2 + 2.8^2 = c^2
7.84 + 7.84 = c^2
15.68 = c^2
√15.68 = √c^2
3.959797 = c
c = 3.96
side c would be side x so x is 3.96

Suppose that you are interested in the relationship between the return rate on a stock in 2010 compared to the return rate in 2009.-You believe that the return rates in both years are positively correlated. A sample of 15 stocks'yields the following regression results: b0=5.3, b1= 1.04, sb= 1.79, and MSE = 35.4. 1:79, sb= 0.2163, R2 = 0.64
i. How would you explain the slope coefficient b1?
ii. What is the least squares regression line?
iii. What is the predicted value of y when x = 5
iv. Calculate the error sum of squares.
v. Calculate the total sum of squares.
vi. Calculate the regression sum of squares.
vii. Prepare the analysis of variance table for regression.
Step-by-step explanation:
1. we have b1 = 1.04 which is positive. we say that the return I. 2009 is positively correlated with the return in 2010.
2. Y = b0 + b1X
Y = 5.3 + 1.04X
3. If x = 5
Y = 5.3 + 1.04(5)
Y = 10.5
4. SSE = mse x (n-2)
n = 15, mse = 35.4
SSE = 35.4 x(15-2)
= 35.4 x 13
= 460.2
5. We are to find SST here
R² = SSR/ SSR + SSE
R² = 0.64
SSE = 460.2
0.64 = SSR/SSR+460.2
Cross multiply
0.64(SSR + 460.2) = SSR
0.64ssr + 294.528 = SSR
Collect like terms
294.528 = SSR - 0.64SSR
294.528 = 0.36SSR
SSR = 294.528/0.36
SSR = 818.13
SST = SSR + SSE
= 818.13 + 460.2
= 1276.53
6. The SSR has been calculated to be 818.13

A bag hes 10 red marbles, 3 green marbles,
7 yelow marbles, and 5 blue merbles. What is
the probability of crowing a red marble and
then g, blue, marble without replacing the first?
Answer:
[tex]\frac{3}{5}[/tex]
Step-by-step explanation:
Probability is the chance of an event happening. One finds the probability of an event by using the following general formula,
[tex]\frac{desired}{total}[/tex]
In this case, the desired outcome is pulling whether a red or blue marble from the bag, the desired equals the sum of the number of red and blue marbles.
(red) + (blue)
= 10 + 5
= 15
The total number of marbles is the sum of all the number of marbles in the bag.
(red) + green) + (yellow) + (blue)
= 10 + 3 + 7 + 5
= 25
Now substitute these values into the formula to find the probability, then simplify,
[tex]\frac{15}{25}[/tex]
Divide both the numerator and denominator by (5),
[tex]\frac{3}{5}[/tex]

What is the y-intercept of the line given by the equation y=5x+16 ?
Answer:
16
Step-by-step explanation:
Slope intercept form is
y = mx + b
m is the slope
b is the y-intercept
-----------------------
y = 5x + 16
is in slope intercept form
b, the y-intercept is 16
which is point (0, 16)
What is the measure, in degrees, of angle b?
The top angle is the same as the bottom angle, since they are vertically opposite angles.
b+20=40
b=40-20
b=20
It is also 20 degrees.
Answer:
Step-by-step explanation:
angle b+20 degree=40 degree(being vertically oppoite angles)
angle b=40-20
angle b=20
therefore angle b=20 degree.
