This is a extremely important geometry im giving brainliest and 50+ points. Provide steps as needed.

A traveling circus with thrill rides Charge 7$ For admission $1.50 For each ride you take. If you pay $29.50 total, how many rides did you take?

I am probably just really dumb, but I don't understand the concept. The question is: -42v+33<8v+91. I am supposed to solve the inequality for v. Please give an explanation and not just an answer, I would really like to know how to do this.

Use the Gram-Schmidt process to find an orthonormal basis for the subspace of R4 spanned by the vectors (1, 0, 1, 1), (1, 0, 1, 0), (0, 0, 1, 1).

If Alpha = 0.05,

1. What is the critical t-value?

2. What is the decision for a statistically significant change in average weights at birth at the 5% level of significance?

**Answer:**

1. Critical value t=±2.447

2. The null hypothesis is failed to be rejected.

At a significance level of 0.05, there is not enough evidence to support the claim that the birth weight significantly differs from 6.6 lbs.

**Step-by-step explanation:**

This is a hypothesis test for the population mean.

The claim is that the birth weight significantly differs from 6.6 lbs.

Then, the null and alternative hypothesis are:

The significance level is 0.05.

The sample has a size n=7.

The sample mean is M=7.56.

As the standard deviation of the population is not known, we estimate it with the sample standard deviation, that has a value of s=1.18.

The estimated standard error of the mean is computed using the formula:

Then, we can calculate the t-statistic as:

The degrees of freedom for this sample size are:

For a two-tailed test with 5% level of significance and 6 degrees of freedom, the critical value for t is ±2.447.

As the test statistic t=2.152 is under 2.447 and over -2.447, it falls in the acceptance region, so the effect is not significant. The null hypothesis is failed to be rejected.

At a significance level of 0.05, there is not enough evidence to support the claim that the birth weight significantly differs from 6.6 lbs.

The tie was marked down by 40%

12 dolars / 20 dolars

the percentage is

(20-12) / 20

= 8/20

= **40 %**

C) 0.317

D) 0.106

**Answer:**

B) 0.894

**Step-by-step explanation:**

In a **Poisson distribution**, the probability that X represents the number of successes of a random variable is given by the following formula:

In which

x is the number of sucesses

e = 2.71828 is the Euler number

is the mean in the given interval.

**A local animal rescue organization receives an average of 0.55 rescue calls per hour.**

This means that

**Probability that during a randomly selected hour, the organization will receive fewer than two calls.**

In which

2 = 4

**Answer:**

x = 16

**Step-by-step explanation:**

x - 12 = 4

+ 12 = +12

x = 16

**Answer:**

16

**Step-by-step explanation:**

Step 2: Multiply 2 × 3.

Step 3: Subtract the two products.

C.Step 1: Divide 1 ÷ 5.

Step 2: Divide 2 ÷ 3.

Step 3: Add the two quotients.

D.Step 1: Divide 1 ÷ 5.

Step 2: Divide 2 ÷ 3.

Step 3: Subtract the two quotients.

**Answer:**

A. Step 1: Multiply 1 × 5.

Step 2: Multiply 2 × 3.

Step 3: Add the two products.

**Step-by-step explanation:**

The total number of miles hiked will be the sum of the numbers of miles hiked each day. Each day, the number of miles hiked can be computed by multiplying time by speed:

distance = speed × time

So, the total number of miles hiked is ...

total miles = miles on day 1 + miles on day 2 . . . . . (*sum*, not a difference—eliminates choice B)

total miles = (speed on day 1)×(time on day 1) + (speed on day 2)×(time on day 2) . . . . . (sum of *products*—eliminates choices C and D)

**Choice A correctly describes the computation**.
