<h2>Answer:</h2>

Option: C is the correct answer.

C. One

<h2>Step-by-step explanation:</h2>

We know that if two lines are parallel then the number of solution to the system of equality is zero.

If two lines overlap then there are infinite number of solutions.

and if two lines intersect at a point then there is a unique solution to the system of equality i.e. one solution.

Based on the graph we observe that the two lines intersect at just one point.

Hence, the number of solutions to the system of equations is:

C. One

27 students are learning to make balloon animals. There are 172 balloons to be shared equally among the students

bija089 [108]

A.) .4 of a balloon is left
To Check:
what I did was divide 172 by 27 and it is 6.37 rounded to ........6 is an equal number so I kept it and .4 will be left over after sharing equally.

B.) 17 more balloons are needs
To Check:
what I was multiply 27 by 7 because each student needs seven balloons and I got 189 after that I subtracted 172 from 189 (189-172=17)
to see how many more balloons are needed.

Answer:

No. There is not enough evidence to support the claim that the population standard deviation is different from $12.

Step-by-step explanation:

The null hypothesis is that the true standard deviation is 12.

The alternative hypothesis is that the true standard deviation differs from 12.

We can state:

$H_0: \sigma=12\\\\H_a: \sigma\neq12$

The significance level is 0.10.

The sample size is n=15, so the degrees of freedom are:

$df=n-1=15-1=14$

The sample standard deviation is 9.25.

The test statistic is

$T=(n-1)(s/\sigma_0)^2=14*(9.25/12)^2=14*0.77^2=14*0.59=8.32$

The critical values for rejecting the null hypothesis are:

$\chi_{0.025,13}=5.00875\\\\\chi_{0.975,13}=24.7356$

As T=8.32 is within the acceptance region (5.01, 24.74), the null hypothesis failed to be rejected.

There is not enough evidence to support the claim that the population standard deviation is different from $12.

At 11:55 p.m., Thomas ties a weight to the minute hand of a clock. The clockwise torque applied by the

ryzh [129]

Answer:

T(t) = 3sin((t-5)π/30)

Step-by-step explanation:

5 minutes after Thomas ties it on, the torque is zero and increasing. So, the sine function is shifted right 5 minutes. The maximum value is 3, so that is the multiplier of the sine function. The period is 60 minutes, so the coefficient of t is (2π/60) = π/30. The function you want is ...

T(t) = 3sin((t-5)π/30)
