Number of T-Shirts Total Cost (dollar)
12
156
17
211
22
266
Which equation best describes the relationship between the total cost, c(t), and the number of T-shirts, t?
ok
Answer:
12
Step-by-step explanation:
hi
Equation which describe relationship between total cost and number of t-shirt is [tex]c(t)=75.93e^{0.06t}[/tex].
Data given are ,
Number of t-shirt (t) total cost c(t)
12 156
17 211
22 266
According to above table, exponential function best describes the relationship between the total cost, c(t), and the number of T-shirts, t.
Let, [tex]c(t)=Ae^{kt}[/tex]
Substitute , t=12 and c(t) = 156
We get, [tex]156=Ae^{12k}.......(1)[/tex]
Substitute , t=17 and c(t) = 211
We get, [tex]211=Ae^{17k} ........(2)[/tex]
After solving above equations.
We get, A = 75.93 and k = 0.06
Thus, [tex]c(t)=75.93e^{0.06t}[/tex]

108 identical books have a mass of 30 kg.Find
the mass of 150 such books
the number of such books that have mass of 20 kg
Answer:
41.67 kg
72 books
Step-by-step explanation:
mass of 150 books = 150/108 × 30 kg
= 41.67 kg
number of books = 20/30 × 108 books
= 72 books
what is the sum of the interior angle in a kite
Answer:
the sum of the interior angles = 360°
A kite has 4 sides.
This is the formula for the sum of the interior angles of any polygon:
N = number of sides
the sum of the interior angles = (N x 180°) - 360°
so, N = 4, then:
(4 x 180°) - 360° = 360°

The tile showen are placed in a bag you randomly select one of the tiles return it to the bag and randomly selecting Lo tile what is the probability that the first number divided by the second number is greater than zero
Answer:
15
Step-by-step explanation:
The probability that the first number divided by the second number is greater than zero is 1/3
What is probability?Probability is the likelihood that an event will occur and is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.
Tiles are numbered -2,-1,1,2
So, possibility first number divided by the second number is greater than zero
-2/-1=2
-2/1=-2
-2/2=-1
-1/-2= 0.5
-1/1=-1
-1/2=-0.5
1/-2=-0.5
1/-1=-1
1/2=0.5
2/-2=-1
2/-1=-2
2/2=1
Probability the first number divided by the second number is greater than zero = 4/12=1/3.

In a hatch chemical process, two catalysts arc being compared for their effect on the output of the process reaction. A sample of 12 batches was prepared using catalyst 1 and a sample of 10 batches was obtained using catalyst 2. The 12 batches for which catalyst 1 was used gave an average yield of 85 with a sample standard deviation of 4, and the second sample gave an average of 81 and a sample standard deviation of 5. Find a 90% confidence interval for the difference between the population means, assuming that the populations are approximately normally distributed with equal variances
Answer:
The 90% confidence interval, C.I = (0.693, 0.7307)
Step-by-step explanation:
Catalysts 1 and catalyst 2 have the following statistical data;
Catalyst 1
The number of batches in the sample, n₁ = 12
The average yield by the 12 batches of catalyst 1, [tex]\overline x_1[/tex] = 85
The sample standard deviation, s₁ = 4
Catalyst 2
The number of batches in the sample, n₂ = 10
The average yield, [tex]\overline x_2[/tex] = 81
The standard deviation, s₂ = 5
F-test = s₂²/s₁² = 5²/4² = 1.5625
The degrees of freedom, df = n₁ + n₂ - 2
∴ df = 12 + 10 - 2 = 20
The critical-t at 90% confidence level = 1.725
The F-test < The critical-t, we pool the variance
The 90% confidence interval with the assumption of equal variance is given as follows;
[tex]The \ 90\% \ confidence \ interval= \left (\bar{x}_{1}- \bar{x}_{2} \right )\pm t_{\alpha /2} \times (s_p) \times \sqrt{\dfrac{1^{2}}{n_{1}}+\dfrac{1^{2}}{n_{2}}}[/tex]
[tex]s_p =\sqrt{\dfrac{\left ( n_{1}-1 \right )\cdot s_{1}^{2} +\left ( n_{2}-1 \right )\cdot s_{2}^{2}}{n_{1}+n_{2}-2}}[/tex]
Therefore;
[tex]s_p[/tex] = √((12 - 1)×4² + (10 - 1)×5²)/(12 + 10 - 2)) ≈ 4.48
Therefore, we get;
[tex]C.I. = \left (85- 81 \right )\pm 1.725 \times 4.48 \times \sqrt{\dfrac{1}{12}+\dfrac{1}{10}}[/tex]
The 90% confidence interval, C.I = 0.693 < μ₁ - μ₂ < 7.307 = (0.693, 0.7307).
PLEASE HELP WILL GIVE BRAINLIEST:) If S (0,2) is the midpoint of RT and the coordinates of T are (3,5), find the coordinates of R.
Answer:
(-3,-1)
Step-by-step explanation:
So we need to find a number, x=a, such that when we average that number and x=3, we get x=0.
Since we want x=0 to be middle and x=3 is 3 units right of 0, then we are looking for number 3 units left of 0 which is x= -3.
Since we want y=2 to be the middle and y=5 is 3 units above 2, then we are looking for a number 3 units below 2 which is y=-1.
The other endpoint is (-3,-1).
Let's average (-3,-1) and (3,5).
(-3+3)/2=0/2=0
(-1+5)/2=4/2=2.

Phil melange 0.2L de jus de pomme teneur en fruit 25% et 0.1L de jus d'orange teneur de fruit 50% quel est la teneur en fruit de son cocktail
Answer:
10%
Step-by-step explanation:
La teneur en fruits de son cocktail est calculée comme suit:
25% de jus de pomme 0.2L + 50% de jus d'orange 0.1L
0.25 × 0.2 + 0.5 × 0.1
0.05 + 0.05
= 0.10
Conversion en pourcentage
= 0.10 × 100%
= 10%
Par conséquent, la teneur en fruits de son cocktail est de 10%
