Brenda cuts her grass every 15 days and trims her shrubs every 24 days. if brenda cut her grass and trimmed her shrubs on june

wariber [46]

To get the number of days that will pass before Brenda cuts her grass and shrubs on the same day will be found using least common multiple:
15=3×5
24=3×8
thus the LCM (24,15)=120 days
She will cut the grass again after 120 days

Create a report about saving money to assist with the cost of the first year of college

andrew-mc [135]

we should save money to help others in need. i believe this because there are smart homeless kids out there who want and need an education. honestly do you want to be the person who gets a homeless person hooked on drugs because they don't have an education. and there are people with houses but they don't have the kind of money for college and if they do not get that scholarship. their life can take a turn for the worst. as for research 82% of people get hooked up on drugs because they lose their education an can not get a job. this can also lead to depression. that is one of strongest inside damage. it is worse than anxiety thats pretty bad. And it is also how people end up on the streets. And also giving money means study supplies and if thy study their education will most likely get better!!

Heights (cm) and weights (kg) are measured for 100 randomly selected adult males, and range from heights of 139 to 192 cm and

Bumek [7]

Answer:

The weight of an adult male who is 158 cm tall is 59.32 kg.

Step-by-step explanation:

The regression equation representing the relationship between height and weight of a person is:

$\hat y=-105+1.04 x$

Here,

y = weight of a person (in kg)

x = height of a person (in cm)

The information provided is:

$\bar x=167.77\ \text{cm}\\\bar y=81.54\ \text{cm}\\r(X, Y)=0.201\\p-value=0.045$

The significance level of the test is, α = 0.01.

The hypothesis to test the significance of the correlation between height and weight is:

H₀: There is no relationship between the height and weight, i.e. ρ = 0.

Hₐ: There is a relationship between the height and weight, i.e. ρ ≠ 0.

Decision rule:

If the p-value of the test is less than the significance level, then the null hypothesis will be rejected and vice-versa.

According to information provided:

p-value = 0.045 > 0.01

The null hypothesis will not be rejected at 1% level of significance.

Thus, concluding that there is no relationship between the height and weight.

Compute the weight of an adult male with height, x = 158 cm as follows:

$\hat y=-105+1.04 x$

$=-105+(1.04\times 158)\\=-105+164.32\\=59.32$

Thus, the weight of an adult male who is 158 cm tall is 59.32 kg.
