Answer:
1 + 13/24 inches (1 inches)
Step-by-step explanation:
Inches is a measurement unit that used to determine length or depth. To solve the question we need to subtract the total rain at Tuesday with the depth of the rain at Monday. In this question, we have 2 numbers with different denominators. To subtract them, we have to change the denominator so it will be the same for both numbers. The way to do this is to multiply both fractions with opposite denominators. The calculation will be:
3 - 2 =
1 - =
1 *- * =
1 - =
1
Answer:
It was hypothesized that more people would choose the number 7 as their 'lucky' number than any other number.
Step-by-step explanation:
Given that one variable chi-square is used to test whether a single categorical variable follows a hypothesized population distribution. The Chi Square statistic compares the tallies or counts of categorical responses between two (or more) independent groups
The null hypothesis (H0) for the test is that all proportions are equal.
The alternate hypothesis (H1) is given condition in the question.
A. It was hypothesized that more people would choose the number 7 as their 'lucky' number than any other number.
This is suited for testing with a one-variable chi-square test because we are testing if the proportion of people who choose number 7 is greater than the proportion of any other numbers. So, we are therefore comparing more than 2 proportions.
B. People who choose the number 7 as their 'lucky' number are significantly more superstitious than people who choose the number 13 as their 'lucky' number.
This is not suited for testing with a one-variable chi-square test. A z test is more preferable in this instance because we are testing just two proportions.
C. Choice of 'lucky' number is directly related to measures superstition.
This is not suited for testing with a one-variable chi-square test because chi square test is not used for showing relationship between variables.
D. All of these. Since option A is correct, this option can not be correct.
Answer:
4x-3 is the expression to your question
<span>Find the prime factor of 105
105 = 3 × 5 × 7
Then </span>Find the prime factor of 20 <span>20 = 2 × 2 × 5
And last </span>Multiply all the common factors obtained in steps i) and ii) above to find the gcf:<span>
GCF = 5</span>
Answer:
Step-by-step explanation:
The easiest and most proper way to approach this task is to combine like terms inside parentheses: (24x + 7 – 12x) => (12x + 7).
Then (1/4)(24x + 7 – 12x) = (1/4)(12x + 7). This is an acceptable answer. There is the option of carrying out the multiplication, which results in
3x + 7/4, which is another acceptable answer.
