Answer:

Rhombus

Step-by-step explanation:

A rhombus is defined as a parallelogram with four equal sides. Is a rhombus always a rectangle? No, because <u>a rhombus does not have to have 4 right angles.</u> Kites have two pairs of adjacent sides that are equal.

Answer:

A rhombus

Step-by-step explanation:

A rhombus has four congruent sides, and does not necessarily have to have right angles. (A square is considered a rhombus and has four right angles, so that is the only exception). So, your answer would be rhombus!

the anwser above me is incorrect!

Answer: 1,045 passengers

Step-by-step explanation:

This question involves multiple steps. Let's first try to figure the number of children on the cruise.

The ratio of girls to the total number of children was 2:5. There are 198 boys.

This information tells me that for every 5 children, there's 2 girls and 3 boys.

Based off of this information, we can divide the total number of boys by 3 in order to find the number of children.

198÷3=66

Let's multiply 66 by 5 since that's the number of groupings based off the ratio.

66×5=330

Let's check the number of children. Since the ratio of girls to total children is 2:5 and we already confirmed there's 198 boys, there should be 132 girls. We can turn this ratio into a fraction where 2/5 of the children are girls. we can confirm this by multiply 330 by 2/5 (0.4) and getting 132.

There are 330 children on the cruise.

The ratio of the number of adults to the number of children was 13:6.

For every 6 children, there were 13 adults. Let's divide the number of children by 6 in order to find the number of groupings.

330÷6=55

Let's now multiply the groupings by 13 to find the number of adults.

55×13=715

So there should be 715 adults and 330 children on the cruise.

715+330=1,045

Given the right angle triangle shown here, calculate:
charle [14.2K]

Answer:

see explanation

Step-by-step explanation:

(1)

(a)

sin(a) = \frac{opposite}{hypotenuse} = \frac{15}{17}

(b)

cos(a) = \frac{adjacent}{hypotenuse} = \frac{8}{17}

(c)

tan(a) = \frac{opposite}{adjacent} = \frac{15}{8}

----------------------------------------------------

(2)

(a)

sin(b) = \frac{opposite}{hypotenuse} = \frac{8}{17}

(b)

cos(b) = \frac{adjacent}{hypotenuse} = \frac{15}{17}

(c)

tan(b) = \frac{opposite}{adjacent} = \frac{8}{15}

Stacy uses a spinner with six equal sections numbered 2, 2, 3, 4, 5, and 6 to play a game. Write a probability model for this ex
allsm [11]

Answer:

We estimate to have 8.33 times the number 6 in 50 trials.

Step-by-step explanation:

Let us consider a success to get a 6. In this case, note that the probability of having a 6 in one spin is 1/6. We can consider the number of 6's in 50 spins to be a binomial random variable. Then, let X to be the number of trials we get a 6 out of 50 trials. Then, we have the following model.

P(X=k) = \binom{50}{k}(\frac{1}{6})^k(\frac{5}{6})^{50-k}

We will estimate the number of times that she spins a 6 as the expected value of this random variable.

Recall that if we have X as a binomial random variable of n trials with a probability of success of p, then it's expected value is np.

Then , in this case, with n=50 and p=1/6 we expect to have \frac{50}{6} number of times of having a 6, which is 8.33.
