NEED HELP 10 POINTS

Mathematics
1 answer:
kobusy [5.1K]3 years ago
4 0

Answer:

1/28

Step-by-step explanation:

Before picking 1st song

Total songs = 8

Rock songs = 2

Probability of picking a rock song as the first song,

= 2 rock songs out of 8 total songs remaining

= 2/8

After picking 1st song

Total songs left over = 7

Rock songs left over = 1

Hence, Probability of picking a rock song as the second song,

= 1 rock song out of 7 total songs remaining

= 1/7

Probability of picking 2 consecutive rock songs,

= \frac{2}{8} x \frac{1}{7}

= \frac{1}{28}

BRAINLIESTT ASAP! PLEASE HELP ME :)<br><br> Solve for x in the figure below. Show your work.
nikdorinn [45]

Answer:

x = 19°

Step-by-step explanation:

we can see from observation that 22° and (3x+11)° are complementary. I.e they add up to 90°

hence

22 + (3x+11) = 90

22 + 3x+11 = 90

33 + 3x = 90   (divide both sides by 3)

11 + x = 30  (subtract 11 from both sides)

x = 30 - 11

x = 19°

Use the normal distribution to find a confidence interval for a proportion p given the relevant sample results. Give the best po
Brrunno [24]

Answer: (0.63, 7.07)

Step-by-step explanation:

The confidence interval for population proportion is given by :-

\hat{p}\pm z_{\alpha/2}\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}

Given :\hat{p} =0.7 ;  n=110

Significance level : 1-0.90=0.1

Critical value :  z_{\alpha/2}=1.645

Now, a 90% confidence interval for population proportion will be :-

0.7\pm (1.645)\sqrt{\dfrac{0.7(1-0.7)}{110}}\\\\\approx0.7\pm0.07\\\\=(0.7-0.07,0.7+0.07)=(0.63,\ 7.07)

Hence, a 90% confidence interval for population proportion = (0.63, 7.07)
