Ian has 22 ounce iced tea. He drinks 10 ounces. Enter the percentage of ounces Ian has left of his iced tea. Round your answer to the nearest hundredth
Answer:
54.55%
Step-by-step explanation:
If he drank 10 ounces, that means he has 12 ounces of the tea left.
Find the percent that he has left by dividing 12 by 22, and multiplying it by 100
(12/22) x 100
= 54.55
So, Ian has approximately 54.55% left of his iced tea

Evaluate the function.
[tex]f(x)=3x^{2} +2x\\\\f(3)=[/tex]
Simply plug 3 into the equation.
[tex]f(3) = 3(3)^2+2(3) = 3(9) + 6 = 27 + 6 = 33\\\\\\f(3) = 33[/tex]
Answer:
Step-by-step explanation:
Plugin x = 3 in the function
f(x) = 3x² + 2x
f(3) = 3*(3)² + 2*3 {3² = 3*3 = 9}
= 3*9 + 6
= 27 + 6
f(3) = 33
. In the casino game roulette, a wheel with 38 spaces (18 red, 18 black, and 2 green) is spun. In one possible bet, the player bets $1 on a single number. If that number is spun on the wheel, then they receive $36 (their original $1 $35). Otherwise, they lose their $1. On average, how much money should a player expect to win or lose if they play this game repeatedly
Answer:
For each game, the player should be expected to lose $0.0263.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
Probability of each outcome:
1/38 probability of winning, that is, 1/38 probability of receiving $36.
37/38 probability of losing, that is, 37/38 probability of losing $1.
On average, how much money should a player expect to win or lose if they play this game repeatedly?
For each game:
[tex]E(X) = \frac{1}{38}*36 - \frac{37}{38}*1 = \frac{36 - 37}{38} = -\frac{1}{38} = -0.0263[/tex]
For each game, the player should be expected to lose $0.0263.

someone please help me answer this correctly
Answer:
13 units is the answer.
Step-by-step explanation:
points (8,-4) and (3,8)
We can rewrite the Pythagorean theorem as,
[tex]d=\sqrt{(x_2 - x_1)^2+(y_2-y_1)^2} \\\\d= \sqrt{(3-8)^2 + (8-(-4))^2} \\\\d=\sqrt{(-5)^2 + (12)^2} \\\\d=\sqrt{25 + 144} \\\\d=\sqrt{169} \\\\d=13\\\\[/tex]
∴ distance between 2 points (8,-4) and (3,8) = 13 units.

What is a clock?A clock, often known as a timepiece, is a device that measures and displays the passage of time.
The clock works in 12 hours time period, therefore, the time between 7 am and 12 pm is 5 hours, similarly, the time between 12 pm and 5 pm is 5 hours.
Thus, the total hours between 7 am and 5 pm is 10 hours(5+5).
(Spanish)
¿Qué es un reloj?
Un reloj, a menudo conocido como reloj, es un dispositivo que mide y muestra el paso del tiempo.
El reloj funciona en un período de tiempo de 12 horas, por lo tanto, el tiempo entre las 7 am y las 12 pm es de 5 horas, de manera similar, el tiempo entre las 12 pm y las 5 pm es de 5 horas.
Así, el total de horas entre las 7 am y las 5 pm es de 10 horas (5+5).

7. The following numerical ordered sequence of numbers has a mean of 13 and a median of 14. 4. a. 8. 10. 13.b. 16. 18. 20:21 Gven this information, the values of a ondo must be:
Answer:
a = 9
b = 19
Step-by-step explanation:
DO B FIRST
The mean is the average of all the terms (numbers) in the sequence
To find the average you find the sum of the terms and divided the sum by the number of terms there are.
The mean times the number of terms equals the sum of all the terms subtract the terms that you know from the sum to get A
a = 17(10)-7-12-15-17-19-20-22-24-25
a = 170-161
a = 9
The median is found by taking the average of the two middle terms
Our middle terms are 17 and B
the median times 2 equals the sum of the two terms and then subtract the term you know from the sum
b = 18(2)-17
b = 36-17
b = 19

Suppose 229 subjects are treated with a drug that is used to treat pain and 52 of them develop nausea use a 0.01 significance level to test the claim that more than 20% of users develop nausea identify the Noel and alternative hypothesis for this test
Answer:
The null hypothesis is [tex]H_o: p \leq 0.2[/tex]
The alternate hypothesis is [tex]H_a: p > 0.2[/tex]
The pvalue of the test is 0.1515 > 0.01, which means that we do not reject the null hypothesis that 20% of less users develop nausea, that is, we have no sufficient evidence that this proportion is larger than 20%.
Step-by-step explanation:
Test the claim that more than 20% of users develop nausea
This means that the null hypothesis is that 20% or less of the users develop nausea, that is:
[tex]H_o: p \leq 0.2[/tex]
And the alternate hypothesis is that more than 20% develop, so:
[tex]H_a: p > 0.2[/tex]
The test statistic is:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.
0.2 is tested at the null hypothesis:
This means that [tex]\mu = 0.2, \sigma = \sqrt{0.2*0.8}[/tex]
Suppose 229 subjects are treated with a drug that is used to treat pain and 52 of them develop nausea.
This means that [tex]n = 229, X = \frac{52}{229} = 0.2271[/tex]
Value of the test statistic:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
[tex]z = \frac{0.2271 - 0.20}{\frac{\sqrt{0.2*0.8}}{\sqrt{229}}}[/tex]
[tex]z = 1.03[/tex]
Pvalue of the test an decision:
Probability of finding a proportion above 0.2271, which is 1 subtracted by the pvalue of z = 1.03
Looking at the z-table, z = 1.03 has a pvalue of 0.8485
1 - 0.8485 = 0.1515
The pvalue of the test is 0.1515 > 0.01, which means that we do not reject the null hypothesis that 20% of less users develop nausea, that is, we have no sufficient evidence that this proportion is larger than 20%.
