I NEED HELP ASAP PLEASE HELP ME!!

yuradex [85]

Not sure if this is for algebra but this is the algebraic solution.
1. 5x + 1y = 25 (x meaning number of nickels) (y meaning number of pennies)
so 3 solutions could be, 5 nickels and 0 pennies, 4 nickels and 5 pennies, 3 nickels and 10 pennies.
2. First calculate how many days till the end of October, (31-14)= 17 days. then add 30 days for the entire month of November. Then add the 5 days that occurred in December. This will leave you with a total of 52 days.

n=400 people under the age of 25 was asked whether they check social media sites right after they wake up. 42% check social medi

Aliun [14]

Answer:

Step-by-step explanation:

We would set up the hypothesis test.

For the null hypothesis,

p = 0.5

For the alternative hypothesis,

p < 0.5

Considering the population proportion, probability of success, p = 0.5

q = probability of failure = 1 - p

q = 1 - 0.5 = 0.5

Considering the sample,

P = 42/100 = 0.42

We would determine the test statistic which is the z score

z = (P - p)/√pq/n

n = 400

z = (0.42 - 0.5)/√(0.5 × 0.5)/400 = - 3.2

Recall, population proportion, p = 0.5

We want the area to the left of 0.5 since the alternative hypothesis is lesser than 0.5. Therefore, from the normal distribution table, the probability of getting a proportion < 0.5 is 0.00069

So p value = 0.00069

Since alpha, 0.05 > than the p value, 0.00069, then we would reject the null hypothesis.

Therefore, there is significant evidence to conclude that that less than 50% of people under the age of 25 check social media sites right after they wake up.

Which function is represented by the graph? f(x) = –|x| 4 f(x) = –|x| – 4 f(x) = –|x 4| f(x) = –|x – 4|.

exis [7]

The function which is represented by the graph attached below shifted 4 units right is similar to option d, which is,

$f(x)=-|x-4|$

<h3>What is a graph of function?</h3>

The linear function has the highest power of the unknown variable one. Thus, the graph plotted for the linear function is a straight line.

Types of function movement over the graph -

Horizontal shift- Let the parent function is $f(x)$ . Thus by replacing parent function with $f(x-b)$ shifts the graph b units right and by replacing parent function with $f(x+b)$ shifts the graph b units left.

Vertical shift- Let the parent function is $f(x)$ . Thus by replacing parent function with $f(x)-c$ shifts the graph b units down and by replacing parent function with $f(x)+c$ shifts the graph b units up.

The graph given in the problem is attached below. All the parents function of the options are absolute function.

In the graph, the parent function 4 units shifted to right. So the -4 should add in the parent function. Thus, by the above definition, this is a horizontal shift of the function and can be written as,

$f(x)=-|x-4|$

Hence, the function which is represented by the graph attached below shifted 4 units right is similar to option d, which is,

$f(x)=-|x-4|$
