Andy bought total of 5 pairs of shoes and soxes. He bought some pairs of shoes and some pairs of soxes.

Set the variabloes as follows:

X = number of pairs of shoes

Y = number of pais of soxes

Which equation shows the total number of shoes and soxes he bought?

2x + 5 y =7

2X + 3 Y = 5

X + Y = 5

7Y - 2x = 5x

Answers

Answer:

The  equation that shows the total number of shoes and soxes he bought is x+y=5.

Step-by-step explanation:

Given that statement says that Andy bought total of 5 pairs of shoes and soxes this means that the equation would indicate that the sum of the number of pairs of shoes plus the number of pairs of soxes is equal to 5, which can be expressed as:

x+y=5

The other answers are not right because the numbers of pairs of shoes and soxes are multiplied by another number and the statement indicates that the pairs of shoes and soxes is equal to 5.

a researcher wants to know the typing speed of the students in a large vocational school. the population standard deviation is previously known to be 2.5 minutes. if the researcher wants a margin of error of 0.50 minute and an alpha level of 0.05, what should be the sample size?

Answers

1) It is known that a laboratory task takes the average person 2.5 seconds. A researcher was interested in whether older people are slower (take longer) on this task. The researcher tested 30 randomly selected 80-year-olds. Their mean time was 2.7 seconds, with an estimated population standard deviation of 1.4 seconds. What should the researcher conclude (use the .05 level)? a. /2 Identify the populations involved: population 1 = _____________________________________________________________________ population 2 = _____________________________________________________________________ b. /2 State the research and null hypothesis: Research Hypothesis = _____________________________________________________________ Null Hypothesis = _________________________________________________________________ c. /6 Determine the characteristics of the comparison distribution (hint: it is a distribution of means): mean of the distribution of means = degrees of freedom = estimated population variance = estimated population standard deviation = variance of the distribution of means = standard deviation of distribution of means = d. /1 Cutoff sample score on the comparison distribution at which we’ll reject H0 (hint: 1 or 2 tails?) = e. /1 Determine your sample’s score on the comparison distribution = f. /1 Accept or reject the null hypothesis? g. /4 Sketch the distributions involved:

[tex]h=8.48\ \text{inches}[/tex]

Step-by-step explanation:

Given that,

Radius of cone, r = 7 inches

Slant height of the cone, l = 11 inches

We need to find the height of the cone. Let the height be h. Using trigonometry to find it as follows :

[tex]h^2+r^2=l^2\\\\h=\sqrt{l^2-r^2}\\\\h=\sqrt{11^2-7^2}\\\\h=8.48\ \text{inches}[/tex]

So, the height of the cone is equal to [tex]8.48\ \text{inches}[/tex].
