Answer:

An isosceles triangle

Step-by-step explanation:

After solving for all the angles In the Triangle ABC,

Angle B = 80

Angle C = 50

Angle A = 50

An isosceles triangle is a triangle that the base angles are equal.

In the image the triangle has two equal angles.

Answer:

ISCOCELES TRIANGLE

Step-by-step explanation:

<BAC is alternate to <ACD and <ABC is alternate to <BCE

So, <BAC = <ACD = 50° and <BCE = <ABC = 80°

<ACD + <ACB +<BCE =180 (sum of angles in a straight line)

50° + <ACB + 80 = 180

<ACB = 180-(80+50)

<ACB = 180 - 130 = 50°

You can see that the base angles <BAC and <ACB are equal(<BAC =50° and <ACB = 50°), so the triangle is an Iscoceles triangle.

How can math help in your daily life? <br> How will it benifit you in the future?
Natali [406]
Math can help you when you go to a store and buy stuff. Like when you go to the store when you're older and giving in money for what your buying. Or seeing if you have enough money to buy stuff. Hope it helps :)

An article describes an experiment to determine the effectiveness of mushroom compost in removing petroleum contaminants from so
alexgriva [62]

Solution :

Let p_1 and p_2  represents the proportions of the seeds which germinate among the seeds planted in the soil containing 3\% and 5\% mushroom compost by weight respectively.

To test the null hypothesis H_0: p_1=p_2 against the alternate hypothesis  H_1:p_1 \neq p_2 .

Let \hat p_1, \hat p_2 denotes the respective sample proportions and the n_1, n_2 represents the sample size respectively.

$\hat p_1 = \frac{74}{155} = 0.477419

n_1=155

$p_2=\frac{86}{155}=0.554839

n_2=155

The test statistic can be written as :

$z=\frac{(\hat p_1 - \hat p_2)}{\sqrt{\frac{\hat p_1 \times (1-\hat p_1)}{n_1}} + \frac{\hat p_2 \times (1-\hat p_2)}{n_2}}}

which under H_0  follows the standard normal distribution.

We reject H_0 at 0.05 level of significance, if the P-value or if |z_{obs}|>Z_{0.025}

Now, the value of the test statistics = -1.368928

The critical value = \pm 1.959964

P-value = $P(|z|> z_{obs})= 2 \times P(z< -1.367928)$

                                     $=2 \times 0.085667$

                                     = 0.171335

Since the p-value > 0.05 and $|z_{obs}| \ngtr z_{critical} = 1.959964$, so we fail to reject H_0 at 0.05 level of significance.

Hence we conclude that the two population proportion are not significantly different.

Conclusion :

There is not sufficient evidence to conclude that the \text{proportion} of the seeds that \text{germinate differs} with the percent of the \text{mushroom compost} in the soil.
