I'm pretty sure u have to make the denominators the same by finding the LCM (least common multiple). so 3/5 would be 9/15 cuz u have to change the numerator by the denominator. so five times three, three times three. so 9/15 and do the same for the other one. 1/3 equals 5/15. sorry i'm not a teacher but i hope i helped. oh and remember to rebel against favoritism in schools and at home.
Answer:
Based on statistical analysis the claim is of 3% of patients developing adverse reaction is valid and there is a drug problem
Step-by-step explanation:
Here we have
Percentage of patients that develop nausea em= 153/5783 *100 = 2.65 %
To test the hypothesis, we put our null hypothesis as
H₀: μ = 3%
Alternative hypothesis is then
Hₐ: μ < 3%
Therefore the test statistic is
![t=\frac{\hat{p}-p_0}{\sqrt{\frac{ p_0( 1- p_0)}{n}}}](https://tex.z-dn.net/?f=t%3D%5Cfrac%7B%5Chat%7Bp%7D-p_0%7D%7B%5Csqrt%7B%5Cfrac%7B%20p_0%28%201-%20p_0%29%7D%7Bn%7D%7D%7D)
P₀ = 0.03
= 0.0265
n = 5783
From the above we have our test statistic as -1.579 from which gives our p value as P = 0.057.
Therefore, as we have our P value less than the confidence level of 0.05, we therefore fail to reject the null hypothesis because there is sufficient statistical evidence that suggest that the proportion of patients who would have adverse reaction to the drug = 3%.
To solve for this, we need to multiply all of our dimensions by each other, and then divide that product by the volume of a piece of the average popcorn.
5 x 3 = 15;
15 x 7 = 105.
105 / 1.125 = 93.33~.
This means that 93 (whole) pieces of popcorn will fit in a bag of 105 inches.
I hope this helps!
Plug in x = -1 to get...
f(x) = 2*x^2 - 6
f(x) = 2*(x)^2 - 6
f(-1) = 2*(-1)^2 - 6 ... note how each x is replaced with -1
f(-1) = 2*(1) - 6
f(-1) = 2 - 6
f(-1) = -4
Answer is choice B) -4
Answer:
3 3/4
Step-by-step explanation:
You need to divide what you had in half 2 1/2 divided by 2 is 1 1/4 then you multiply the denominator of the jar and you get 3 3/4.
