Saba spent 2/3 of the pay from her Saturday job, on clothes.
She spent 1/6 in an internet café.
(i) What fraction did she spend in all? ( in simplest form)
(ii) What fraction is left with her?
Answer: (i) 5/6
(ii) 1/6
Step-by-step explanation:
Her money spent in clothes = 2/3
her money spent in internet cafe = 1/6
total fraction spent =
2/3 + 1/6
= 4+1/6
= 5/6
fraction left with her =
1 - (5/6)
= 1/6

3.1.8 When conducting a two-sided test of significance, the value of the parameter under the null hypothesis is plausible and will be contained in a 95% confidence interval when: a. The p-value is less than or equal to 0.05. b. The p-value is greater than 0.05. c. There is no relationship between the p-value and the confidence interval.
Answer:
b. The p-value is greater than 0.05.
Step-by-step explanation:
When we are testing a hypothesis, we have to look at the pvalue.
If the pvalue is less than the significance level, the null hypothesis is not plausible. Otherwise, if the pvalue is more than the significance level, the null hypothesis is plausible.
In this question:
95% means that the significance level is of 1 - 0.95 = 0.05.
Null hypothesis being plausible means that the pvalue is greater than the significance level, that is, greater than 0.05. So the correct answer is given by option b.
The National Survey on Drug Use and Health also reported that 21% of males in the same age group (12-20) are binge drinkers. Suppose that in addition to the 10 randomly chosen females, a random sample 10 males from the same age group is chosen (to a total of 20). Let the random variable Y be the total number of males and females (out of 20) who are binge drinkers. Which of the following is true regarding the random variable Y?
a. Y has a binomial distribution with n-60 and p.16
b. Y does not have a binomial distribution since p, the probability of being a binge drinker, is not the same for all the trials.
c. Y has a binomial distribution with n-60 and p .31
d. Y does not have a binomial distribution since the number of trials n is not fixed.
e. Y does not have a binomial distribution since the trials are not independent.
Answer:
Y does not have a binomial distribution since p, the probability of being a binge drinker, is not the same for all the trials.
Step-by-step explanation:
For a binomial distribution, condition required include :
A fixed number of trials ; Here the number of trials is 20 ; hence, this condition is met.
Each trial must be independent : yes, it is independent as a selected individual could either be a binge drinker or not. The outcome of each trial is either a success or a failure ; being a drinker or not.
However, the probability of being a binge drinker (that is probability of success) could vary for male and female. The probability of male being a binge drinker is 0.21 while that if female isn't specified, this probability, p value should be the same for all trials. Hence, with this value not being the same for all trials, the binomial probability condition is violated.
what is the next number of 1 2 6 17 47 ?
and how?!
2 , 6 , 17 , 47 , 108 , ...
t(n) = 2n^3 - 8.5n^2 + 15.5n - 7
The Next term of sequence is 2n³ - 8.5n²+ 15.5n - 7.
What is Sequence?A sequence is an enumerated group of items in mathematics where repetitions are permitted and order is important. Similar to a set, it has members (also called elements, or terms). The length of the series is the number of elements (potentially infinite).
Given:
Sequence:1 2 6 17 47
By looking at the sequence we have the formula
t(n) = 2n³ - 8.5n²+ 15.5n - 7
So, the next term of Sequence would be
t(6)= 2(6)³ - 8.5(6)²+ 15.5(6) - 7
t(6) = 108
Hence, the next term is 108.

(1 point) Find a formula for the nth term in the sequence: 17,−17/8,17/27,−17/64,17/125,…
Given:
The sequence is:
[tex]17,-\dfrac{17}{8},\dfrac{17}{27},-\dfrac{17}{64},\dfrac{17}{125},...[/tex]
To find:
The formula for the nth term in the given sequence.
Solution:
We have,
[tex]17,-\dfrac{17}{8},\dfrac{17}{27},-\dfrac{17}{64},\dfrac{17}{125},...[/tex]
The given sequence can be written as
[tex]\dfrac{17}{1^3},-\dfrac{17}{2^3},\dfrac{17}{3^3},-\dfrac{17}{4^3},\dfrac{17}{5^3},...[/tex]
The sign are alternative and the absolute value of each term can be defined by the expression [tex]\dfrac{17}{n^3}[/tex], where n is a natural number.
So, the required formula is:
[tex]a_n=(-1)^{n+1}\dfrac{17}{n^3}[/tex]
Therefore, the formula for nth term in the given sequence is [tex]a_n=(-1)^{n+1}\dfrac{17}{n^3}[/tex].
Caterpillar nitrogen assimilation and body mass. we explored the relationship between nitrogen assimilation and body mass (both on log scales) for data on a sample of caterpillars in Caterpillars. The Instar variable in the data codes different stages (1 to 5) of caterpillar development.
a. Fit a model to predict log nitrogen assimilation (LogNassim) using log body mass (LogMass). Report the value of for this model.
b. Fit a model to predict LogNassim using appropriate indicators for the categories of Instar. Report the value of for this model and compare it to the model based on LogMass.
c. Give an interpretation (in context) for the first two coefficients of the fitted model in (b).
d. Fit a model to predict LogNassim using LogMass and appropriate indicators for Instar. Report the value of and compare it to the earlier models.
e. Is the LogMass variable really needed in the model of part (d). Does the linear trend appear to be better when the caterpillars are in a free growth period? (Again, we are not ready to fit more complicated models, but we are looking at the plot for linear trend in the two groups.)

Which equation has a slope of -1 and an x-intercept of (2,0)
Answer:
A (x+y=2)
Step-by-step explanation:
in order to see the slope value and to turn the equation into the slope-intercept form (y=mx+b). Basically we just solve for y and look at the coefficient of x. Then to see the value of the x-intercept we need to give y zero and then solve for x.
a) x+y=2
y=-x+2 (slope is -1)
when y=0 ; 0=-x+2 ; x=2 (x-int=2)
b) x-y=-2
y=x+2 (slope≠-1, it is +1 so this not the answer)
c) x+y=-2
y=-x-2 (slope is -1)
when y=0 ; 0=-x-2 ; x=-2 (x-int≠2 it is -2 so this not the answer)
d) x-y=2
y=x-2 (slope≠-1, it is +1 so this not the answer)
the answer is A (x+y=2)
Answer:
x + y = 2.
Step-by-step explanation:
Using the standard form
y = mx + b
the equation is
y = -1x + b
Now as the x intercept is (2, 0), x = 2 when y = 0 so:
0 = -1(2) + b
2 = b
b = 2
so we have
y = -x + 2
y + x = 2.

Ashton bought 5 cans of olive oil. Each can had a radius of 3.2 inches and was 15 inches tall. Find the total cubic inches of olive oil Ashton had.
Step-by-step explanation:
A can is a cylinder.
Volume of a can = Volume of Cylinder
[tex] = \pi {r}^{2} h[/tex]
Given Radius = 3.2 inches and height = 15 inches,
Volume of one olive oil can =
[tex]\pi( {3.2}^{2} )(15) \\ = 153.6\pi {in}^{3} [/tex]
Volume of 5 olive oil cans = 5 x volume of one olive can
[tex] = 5 \times 153.6\pi \\ = 768\pi {in}^{3} [/tex]

Answer: 15a+8b
Step-by-step explanation:
Answer:
15a + 8b
you multiply 2 by the numbers in the parantasis so our new equasion will be 10a + 6b +5a +2b. You can only add numbers that have THE SAME VARIABLE. So 10a+5a=15a and 6b+2b=8b so our answer is 15a+8b
1. Joshua has a ladder that is 12 ft long. He wants to lean the ladder against a vertical wall so that the top of the ladder is 11.8 ft above the ground. For safety reasons, he wants the angle the ladder makes with the ground to be no greater than 75°. Will the ladder be safe at this height? Show your work and draw a diagram to support your answer.
Answer:
So we'll use trig to solve this because it's a right triangle. The hypotenuse is the ladder (h) and the two smaller sides are the ground and the vertical wall (w).
That angle ladder makes with the ground = €
SOH: sin € = opposite/hypotenuse
No the ladder won't be safe!!!
Now let's make it safe:
The ladder's length (w) is constant, so stays 12
So now let's ask in an inequality what height will be safe (75° or less)
what does that mean?? well as long as you put the ladder against the wall so that the height from ground to top of the ladder is < 11.6 ft!!
Hope that helps! :-D

not safe it is 78.5 degrees
