Step-by-step explanation:
A freshly isolatedsample of 90Y was found to have an activity of 8.9 x 105 disintegrations per minute at 1:00pm on December 3, 2003. At 2:15pm on Dec, 17, 2003, its activity was redetermined and found to be 2.6 x 104 disintegrations per minute. Calculate the half-life of 90Y.
Answer:
3960 minutes
Step-by-step explanation:
From;
0.693/t1/2 = 2.303/t log No/N
t1/2 = half life of 90Y
No = initial activity of 90Y = 8.9 x 10^5 disintegrations per minute
N= activity of 90Y after time t = 2.6 x 10^4 disintegrations per minute
t = time taken
Since the time elapsed is 20,235 minutes, we substitute into the formula above.
0.693/t1/2 = 2.303/20235 log 8.9 x 10^5/2.6 x 10^4
0.693/t1/2 = 1.75 * 10^-4
t1/2 = 0.693/ 1.75 * 10^-4
t1/2 = 3960 minutes

oduced the test statistic χ2=8.95 with a corresponding p-value of 0.03. Which of the following is correct? There is sufficient evidence to reject the null hypothesis at the 0.05 level since the test statistic is greater than the p-value. Answer A: There is sufficient evidence to reject the null hypothesis at the 0.05 level since the test statistic is greater than the p -value. A
Answer:
The null hypothesis must be rejected
Step-by-step explanation:
Here the P value is less than 0.05
which means that the test results are statistically significant and there are sufficient evidence to reject the null hypothesis and accept the alternative hypothesis.
Hence, the null hypothesis must be rejected.
In a lab experiment, 610 bacteria are placed in a petri dish. The conditions are such that the number of bacteria is able to double every 23 hours. How long would it be, to the nearest tenth of an hour, until there are 1040 bacteria present?
Answer:
It would take 19 hours and 36 minutes until there are 1040 bacteria present.
Step-by-step explanation:
Given that in a lab experiment, 610 bacteria are placed in a petri dish, and the conditions are such that the number of bacteria is able to double every 23 hours, to determine how long would it be, to the nearest tenth of an hour, until there are 1040 bacteria present, the following calculation must be performed:
610X = 1040
X = 1040/610
X = 1.7049
2 = 23
1.7049 = X
1.7049 x 23/2 = X
39.2131 / 2 = X
19.6 = X
100 = 60
60 = X
60 x 60/100 = X
36 = X
Therefore, it would take 19 hours and 36 minutes until there are 1040 bacteria present.
A researcher collected data on years spent in college and yearly income. He found that the longer someone is in college, the lower his/her income is. Which of the following is true based on this research? Select all that apply.
The line of best fit for this data would be increasing from left to right on the scatter plot.
The slope of the line of best fit for this data would be negative.
The -intercept for the line of best fit for this data would be zero.
The line of best fit for this data is horizontal because the variables are not related.
If you divided the data into two groups and found the average years of college and average yearly income from each of the two groups, you could find the estimated slope of the line of best fit by using the slope formula on those representative points.

the store is selling lemons at 0.53 each. each lemon yields about 2 tablespoons of juice. how much will it cost to buy enough lemons to make three 9inch lemon pies, each requiring half a cup of lemon juice?
Answer:
$6.36
Step-by-step explanation:
3 pies require 3/2 cups of lemon juice
16 tablespoons = 1 cup
need 24 tablespoons of lemon juice
need 12 lemons at $0.53 each
total cost = 12 x 0.53 = $6.36

log(x)²=(logx)², find the value of x
Answer:
x = 7.39
Step-by-step explanation:
log(x)²=(logx)², find the value of x
log x² = log x * log x
2log x = log x * log x
2 = log x
Take the exponent pf both sides
e² = e^logx
e² = x
x = e²
x = 7.39

A pollster believes that 20% of the voters in a certain area favor a bond issue. If 49 voters are randomly sampled from the large number of voters in this area, approximate the probability that the sampled fraction of voters favoring the bond issue will not differ from the true fraction by more than 0.08. (Round your answer to four decimal places.)
Answer:
The probability that the sampled fraction of voters favoring the bond issue will not differ from the true fraction by more than 0.08 is 0.7698
Step-by-step explanation:
Given

X/n -p < 0.06
x-np <0.06n
x-np <0.06 * 64
x-np <3.84

Answer:
The dimensions of the rectangle are:
2a^2b^2 and 3ab^2 + 5a + 7b
Step-by-step explanation:
The question is asking for the length and width of the rectangle, and gives you an equation that shows the area of the rectangle. It says to factor out the GCF to find these dimensions. In simpler terms, the question wants you to divide the equation for the area, 6^3b^4 + 14a^2b^3 + 10a^3b^2, into two different equations for the length and width, which can't be divided more.
We have three terms to find the greatest common factor (GCF) of. 6^3b^4, 14a^2b^3, and 10a^3b^2. First, let's factor out the 2. This leaves us with
2(3^3b^4 + 7a^2b^3 + 5a^3b^2)
It seems like we're done with factoring out coefficients, for 3, 5, and 7 are all prime. Now, variables. Each term has a factor of a^2b^2. (not more, for this is the limit of 14a^2b^2.)
2a^2b^2(3ab^2 + 7b + 5a) . (this is the same as the answer above, but I changed the order of 7b and 5a there because some online things are specific and don't like it if you don't put the equations in order.)
And that's it!

A ski resort claims that there is a 75% chance of snow on any given day in January and that snowfall happens independently from one day to the next. A family plans a four-day trip to this ski resort in January. Let X represent the number of days it snows while the family is there. What are the mean and standard deviation of X?
Option Choices:
Answer:
Its D
Step-by-step explanation:
Using the binomial distribution, it is found that the mean and the standard deviation of X are given as follows:
[tex]\mu_X = 3, \sigma_X = 0.87[/tex]
What is the binomial probability distribution?The expected value of the binomial distribution is:
[tex]\mu_X = np[/tex]
The standard deviation of the binomial distribution is:
[tex]\sigma_X = \sqrt{np(1-p)}[/tex]
In this problem, the proportion and the sample size are given as follows:
p = 0.75.n = 4.Hence, the mean and the standard deviation are given by:
[tex]\mu_X = np = 4(0.75) = 3[/tex]
[tex]\sigma_X = \sqrt{np(1-p)} = \sqrt{4(0.75)(0.25)} = 0.87[/tex]
