Answer:

m∠1 = 105°

m∠2 = 75°

Step-by-step explanation:

Lines a and b are parallel.

1. Angles 1 and 75° are the same side angles when two parallel lines a and b are cut by transversal t.

The same side angles add up to 180°, so

m∠1 + 75° = 180°

m∠1 = 180° - 75°

m∠1 = 105

2. Angles 2 and 1 are supplementary (add up to 180°), then

m∠1 + m∠2 = 180°

m∠2 = 180° - 105°

m∠2 = 75°

Suppose that in a random selection of 100 colored candies, 26% of them are blue. The candy company claims that the percentage

quester [9]

Answer: a) -0.2252, b) 0.8219

Step-by-step explanation:

Since we have given that

Sample size n = 100

Probability that candies are blue = p= 0.26

Probability that company claims that it is blue candy = P = 0.27

So, Q = 1-P= 1-0.27 = 0.73

So, Null hypothesis : $H_0:p=P$

Alternate hypothesis : $H_1:p\neq P$

So, the test statistic would be

$z=\dfrac{p-P}{\sqrt{\dfrac{P.Q}{n}}}\\\\z=\dfrac{0.26-0.27}{\sqrt{\dfrac{0.27\times 0.73}{100}}}\\\\z=-0.2252$

Since α = 0.05

So, critical value of z = 1.96

p-value = P(Z>Z(calculated)

Using the excel function , we get that

$P(z>0.2252)\\\\=2\times 0.410.911845\\\\=0.8219$

Hence, a) -0.2252, b) 0.8219

What does 2.975 round to?

Nezavi [6.7K]

2.975 round up to 3.

2.975 rounded up to the nearest hundredths is 2.98
2.975 rounded up to the neared tenths will automatically be 3. because 0.97 rounded up to the neared tenths will result to 1.0.

2.975 rounded up to the nearest ones is 3.

Any number that must be rounded to the nearest place must be aware of the number next to it. If the following number is 5 and up, the number place is rounded up. If the next number is 4 and below, the number place is rounded down.
