Answer:
C. It is increasing and concave up because y′>0 and y′′>0.
Step-by-step explanation:
The curve C is a hyperbola in the 2nd and 4th quadrants. As such, it has no maximum or minimum. It is increasing at an increasing rate at the point (-2, 2), so matches the description of choice C.

A random sample of 17 students, taught in traditional lab sessions, had a mean test score of 71.5 with a standard deviation of 4.8. A random sample of 13 students, taught using interactive simulation software, had a mean test score of 78.5 with a standard deviation of 6. Do these results support the claim that the mean science test score is lower for students taught in traditional lab sessions than it is for students taught using interactive simulation software
Answers
Answer:
The calculated value of t= -0.9468 does not lie in the critical region t= -1.701. Therefore we accept our null hypothesis that mean science test score is lower for students taught in traditional lab sessions than it is for students taught using interactive simulation software at the 0.05 significance level
Step-by-step explanation:
Categories Sample Size Mean Standard D
Traditional Lab 17 71.5 4.8
Software 13 78. 5 6
We are using Student's t- test considering that the population variance is equal.
We formulate null and alternate hypotheses are
H0 : u1 < u2 against Ha: u1 ≥ u 2
The Significance level alpha is chosen to be ∝ = 0.05
The critical region t ≤ -t (0.05, 28) = -1.701
Degrees of freedom is calculated df = υ= n1+n2- 2= 17+13-2= 28
Here the difference between the sample means is x`1- x`2= 71.5-78.5= -7
The pooled estimate for the common variance σ² is
Sp² = 1/n1+n2 -2 [ ∑ (x1i - x1`)² + ∑ (x2j - x`2)²]
= 1/17+13-2 [ 71.5²+78.5²]
Sp = 20.0664
The test statistic is
t = (x`1- x` ) /. Sp √1/n1 + 1/n2
t= -7/ 20.0664 √1/17+ 1/13
t= -7/7.393
t= -0.9468
The calculated value of t= -0.9468 does not lie in the critical region t= -1.701. Therefore we accept our null hypothesis that mean science test score is lower for students taught in traditional lab sessions than it is for students taught using interactive simulation software at the 0.05 significance level
The student council needs posters for the Winter Carnival. The print shop charges $15 for each print job. Each poster will cost an additional
$1.35.
Which equation shows the relationship between the number of posters, n, and the total cost, c, in dollars?
O A. c = 1.35n + 15
O B. n = 1.35n + 15
O C. c = 16.35n
O D. n = 16.35c
Answers
Answer: A. c = 1.35n + 15
Step-by-step explanation:
Given: Charge for each job = $15
Additional cost per poster = $ 1.35
Total cost = Charge for each job + (Additional cost per poster) (Number of posters) ...(i)
Varaibles:
c= Tota; cost for n posters.
Substitute all values in (i), we get
[tex]c=15+1.35n[/tex]
Hence, the required equation : c = 1.35n + 15
Hence, the correct option is A. c = 1.35n + 15.

Step-by-step explanation:
When we solve for this we should always remember this formula [tex]a^2+b^2=c^2[/tex] and since we already know a and b we can plug that in to find out what c could be but we won't actually solve it.
[tex]a^2+b^2=c^2\\4^2+4^2=c^2\\16+16=c^2\\32=c^2\\\sqrt{c^2}=\sqrt{32}\\c=\sqrt{32}[/tex]

Suppose there are 17 jelly beans in a box -2 red, 6 blue, 4 white, and 5 green what part of the jelly beans is blue? Express your answer in each of the forms requested
Answers
Answer:
Blue part = [tex]\dfrac{6}{17}[/tex]
Step-by-step explanation:
Given that,
Total number of jelly beans = 17
Red beans = 2
Blue beans = 6
White beans = 4
Green beans = 5
We need to find what part of the jelly beans is blue.
[tex]F_b=\dfrac{\text{Blue beans}}{\text{Total beans}}\\\\F_b=\dfrac{6}{17}[/tex]
Hence, the required part of the jelly beans that is blue is [tex]\dfrac{6}{17}[/tex].
Samuel runs around a 1-mile track in 10 minutes, and Sophia runs around the same track in
10 minutes. Assuming they continue running at their respective speeds, how many total
miles will they run in 35 minutes? Express your answer as a mixed number.
Answers
Answer:
3.5 miles
Step-by-step explanation:
Step one:
given data
Samuel runs around a 1-mile track in 10 minutes
Samuel's speed is
speed= distance/time
speed= 1/10= 0.1 miles per minute
Sophia runs around the same track in 10 minutes
Hence Sophia's speed is also = 0.1 miles per minute
Step two:
Given that the time is 35 minutes, and their speeds are 0.1 miles per minute, we can find the distance from
speed= distance/time
distance= speed*time
distance= 0.1*35
distance= 3.5 miles

This graph represents a transformation of the parent cube root function. Replace the values of h and k to create the equation of the transformed function.
Answers
The equation of the transformed function, y = ∛x+5 - 2
What is parent function?A parent graph is the graph of a relatively simple function. By transforming the function in various ways, the graph can be translated, reflected, or otherwise changed.
This graph represents a transformation of the parent cube root function.
Here, Parent cube root function is
y= ∛x
and the value of h and k is equal to 0
Now, as from the graph we can see that the graph changes direction at (-5,-2) which shows the graph is shifted 5 units to left and 2 unit down
Hence, the equation of the transformed function, y = ∛x+5 - 2
