A USA Today/CNN/Gallup survey of 369 working parents found 200 who said they spend too little time with their children because o

KengaRu [80]

Answer: a. 0.542

b. 0.051

c. $(0.491,\ 0.593)$

Step-by-step explanation:

Let p be the population proportion of parents spend too little time with their children because of work commitments

As per given , we have

n= 369

$\hat{p}=\dfrac{200}{369}=0.542005420054\approx0.542$

Since the sample proportion is the best estimate for the population proportion.

So , the point estimate of the proportion of the population of working parents who feel they spend too little time with their children because of work commitments = 0.542

z-value for 95% confidence interval : $z_{\alpha/2}=1.96$

Margin of error : $E=z_{\alpha/2}\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}$

$E=(1.96)\sqrt{\dfrac{0.542(1-0.542)}{369}}\\\\=0.0508364564574\approx0.051$

The margin of error = 0.051

Confidence interval : $\hat{p}\pm E$

$0.542\pm0.051\\\\=(0.542-0.051,\ 0.542+0.051)\\\\=(0.491,\ 0.593)$

95% confidence interval estimate of the population proportion of working parents who feel they spend too little time with their children because of work commitments : $(0.491,\ 0.593)$

An atom of chlorine has 36 fewer protons than an atom of iodine. Together an atom of chlorine and an atom of iodine have 70 prot

scoundrel [369]

Since a atom of chlorine has 36 fewer protons than an atom of iodine, then their total is 70.
So you have to subtract 36 from 70
70 - 36
= 34

*your answer is 34 protons for an atom of iodine

During a bike challenge, riders have to collect various colored ribbons. Each 1/2 mile they collect a red ribbon, each 1/8 mile

Inessa [10]

Answer:

Hence, a blue and a green ribbon will be collected at the 3/4 marker.

Step-by-step explanation:

During a bike challenge, riders have to collect various colored ribbons.

Each 1/2 mile they collect a red ribbon, each 1/8 mile they collect a green ribbon, and each 1/4 mile they collect a blue ribbon.

We are asked to find which colors of ribbon is collected at the 3/4 mile marker.

since 1 red ribbon is collected at 1/2 mile the next ribbon will be collected at 1 mile.

so he will not reach at the 3/4 marker to get a red ribbon

Hence, no red ribbon will be collected at 3/4 marker.

Now each green ribbon is collected at 1/8 mile.

since, 1/8+1/8+1/8+1/8+1/8+1/8=6/8=3/4

i.e. adding 1/8 6 times we get 3/4

Hence, he will reach the 3/4 marker and get a green ribbon.

Now we are given that each blue marker is obtained at 1/4 marker.

since 1/4+1/4+1/4=3/4

Hence, a blue ribbon will be given at a 3/4 marker.

Hence, a blue and a green ribbon will be collected at the 3/4 marker.
