Answer:
39 / 3 = 13
Step-by-step explanation:
first find out how many times 39 goes into 3 by writing the multiplication facts of 3.
3x1=3 3x8=24
3x2=6 3x9=27
3x3=9 3x10=30
3x4=12 3x11=33
3x5=15 3x12=36
3x6=18 3x13=39
3x7=21 3x14=42
You use 3x13 because 3x13 equals to 39 and that is our dividend.
The answer is 13

16. If there are 75 calories in 220 grams of an artificial sweetener, how many calories would be
in 484 grams of that same artificial sweetener?
d. 165 calories
a. 150 calories
b. 155 calories
c. 160 calories
Answer:
d. 165 calories
Step-by-step explanation:
First of all, we would find the amount of calories in 1 gram of the artificial sweetener
1 gram = 220/75
1 gram = 2.93 calories
Therefore, 484 grams has;
484 * 2.93 = 165.2
Approximately, this is equal to 165 calories.
Method 2
220 grams of the artificial sweetener has 75 calories.
484 grams of the artificial sweetener has x calories.
Translating the word problem into an algebraic equation, we have;
220 = 75
484 = x
Cross-multiplying, we have;
220x = 75*484
220x = 36300
x = 36300/220
x = 165 calories.

Of 1000 randomly selected cases of lung cancer, 823 resulted in death within 10 years. a. Calculate a 95% two-sided confidence interval on the death rate from lung cancer. b. Using the point estimate of p obtained from the preliminary sample, what sample size is needed to be 95% confident that the error in estimating the true value of p is less than 0.03
Answer:
a. The 95% confidence interval is 0.799<p<0.847
b. The sample size n is 622
Step-by-step explanation:
A
P^ = 823/1000
= 0.823
At 95% confidence interval
P^ +- z-alpha/2√p^(1-p^)/n
z-alpha/2 = 1.96
When we insert values we get:
0.823+-1.96√0.823(1-0.823)/1000
= 0.823+-1.96√0.000145671
= 0.823+-1.96(0.012069)
= (0.8467, 0.7993)
The 95% confidence interval is 0.799<p<0.847
B.
We are to compute the sample size here.
The formula and full calculation has been done in the attachment.
4268.4x0.145671
= 621.78
= 622
n = 622
A path for a new city park will connect the park entrance to Main Street, as shown to the right. The path should be perpendicular to Main Street. What is an equation that represents the path?
Answer:
[tex] y = -\frac{1}{2}x + 3 [/tex]
Step-by-step explanation:
To create an equation in slope-intercept form, y = mx + b, for the path, we need to find slope (m) of the path, and also determine the y-intercept (b) of the path.
First, find the slope of the main street:
Using two points on the main street, (2, 3) and (3, 5),
[tex] slope (m) = \frac{y_2 - y_1}{x_2 -x_1} = \frac{5 - 3}{3 - 2} = \frac{2}{1} = 2 [/tex]
Since the path would be perpendicular to the main street, therefore, the slope of the path would be the negative reciprocal of 2.
Thus, the slope of the path, m = -½.
The y-intercept of the path is the point at which the line of the path cuts across the y-axis.
The path intercepts the y-axis at y = 3. Therefore, the y-intercept (b) = 3.
Substitute m = -½, and b = 3 into [tex] y = mx + b [/tex].
✅The equation that represents the path would be:
[tex] y = -\frac{1}{2}x + 3 [/tex]

A small order of fries at Wendy’s has 90 more calories than the small order of fries at McDonald’s. If together they have 550 calories, how many calories are in the Wendy’s small order of fries?
Answer:
320 caloriesStep-by-step explanation:
Small order of fries at Wendy’s = x calories
Small order of fries at McDonald’s = y calories
x = y + 90x + y = 550Substitute x in the second equation
y + 90 + y = 5502y = 550 - 902y = 460y = 230Then, x is:
x = 230 + 90 = 320 caloriesWhich algebraic expression is equivalent to the expression below?

Step-by-step explanation:
PQRS
PQ + QR + RS + PS = 186
RS = SP - 7
PQ = RS = x - 7
QR = PS = x
2x + 2(x - 7) = 186
4x = 200
x = 50
PQ and RS = 43
QR and SP are 50

(04.02 LC) The graph below shows the numbers of cups of apple juice that are mixed with different numbers of cups of lemon-lime soda to make servings of apple soda: What is the ratio of the number of cups of apple juice to the number of cups of lemon-lime soda? (5 points)
Answer:
Ratio of the number of cups of apple juice to the number of cups of lemon lime soda is 6 : 1
Step-by-step explanation:
From the graph attached,
Number of cups of apple juice (A) is proportional to the number of cups of lemon lime soda (L).
A ∝ L
A = kL
Here 'k' is the proportionality constant.
k = [tex]\frac{A}{L}[/tex]
= [tex]\frac{6}{1}[/tex]
Therefore, ratio of the number of cups of apple juice to the number of cups of lemon lime soda is 6 : 1.
