Sales of ice cream are correlated with the temperature. This might seem to have a direct relationship at first glance. However, as the temperature rises, ice cream sales don't always follow. On a basic level, you require people and access to ice cream.

A positive correlation coefficient denotes a direct association between the two variables, such as the increase in ice cream sales with rising outdoor temperatures.

Sales of the dependent variable (ice cream) respond favorably to the independent variable in this excellent illustration of significant positive correlation (temperature). Strong correlation between the two variables suggests that they have a close link under typical conditions.

Therefore, The relationship between temperatures and ice cream sale is correlation coefficient.

chromosomes is the answer.

The physical activities that I did this week were mixed between running, cycling, yoga, and workout.

This week I distributed my physical activities as follows:

Start the week running at low intensity for an hour.

The idea of this exercise is to recover the body from the effort made over the weekend. Heart rate should not exceed 140 bpm.

This day I did a 2-hour cycling session to train my stamina. Therefore, I did a route of more or less 50km at low intensity. Heart rate should not exceed 140 bpm.

This day I did a gym workout with weights.

I did 4 sets of 10 reps lifting weights at different angles. In this exercise, the heart rate goes up during the series and should go down during the rest interval.

This day I did intense running series. To do this, I warmed up for 20 minutes and then did 10 series of 30 seconds at maximum speed with 2-minute rest intervals. In these series, the heart rate increases during intensity and decreases during rest.

This day I did a training session in the gym focused on the lower body. Based on the above, I did leg press and squats for 4 sets of 10 reps. In this exercise, the pulsations remain stable because they do not require high intensity.

This day I did a yoga session to rest from the training of the whole week. I did relaxation stretches and joint movements. In this session, the heart rate should be as low as possible.

This day I did a high intensity cycling session. I did 10 sets of 2-minute strength and then did 30-second sprints. In this session the maximum heart rate is reached.

Answer:  Bakari is correct

Explanation:

Bakari is correct. If he divided both the radius and height by the same factor (in this case, 8), then the resulting scale model will have the same proportions as the original building, just scaled down by a factor of 8. The formula for the volume of a cylinder is V = πr²h, which only has two variables (the radius and height). So if Bakari wants to maintain the same proportions of the cylinder in his scale model, he needs to divide both the radius and height by the same factor. This will result in a scale model with a volume that is 1/8th the volume of the original building.

Answer:

Ratio of height of model to height of the actual Building = 5 : 614

Explanation:

Given:

ATT Building height = 614 feet tall

Model of building = 60 inches tall

Find:

Ratio of height of model to height of the actual Building

Computation:

ATT Building height = 614 feet tall = 614 x 12 = 7,368 inch

Ratio of height of model to height of the actual Building = Model of building / ATT Building height

Ratio of height of model to height of the actual Building = 60 / 7,368

Ratio of height of model to height of the actual Building = 5 : 614

The Ratio of the height of the model the actual ATT Building is 5 / 614

An equation is an expression used to show the relationship between two or more numbers and variables.

12 inches = 1 feet.

Height of model = 60 inches = 60 in. * 1 ft. per 12 in. = 5 ft.
