Answer:
The cow has a greater heart rate than the horse.
Step-by-step explanation:
The question demand we calculate the heart beat of each animal in relation to time . The number of heart beat per unit time can be computed as follows .
The horse heart rate is 440 heart beat in 10 minutes . The heart rate can be simplified as
Rate = 440/10
Rate = 44 heart beat per minute
The cow heart rate can be simplified as
Rate = 390/6
Rate = 65 heart beat per minute
From the Heart rate calculated above the cow has a higher heart rate than the horse.

mean number of points Holly scores is 20 with
a standard deviation of 2. The mean number
of points Juanita scores is 12 with a standard
deviation of 1.25. Whose score is better relative
to her average number of points per game?
Answer:
Juanita's score was better
Step-by-step explanation:
Juanita scored 6.4 points above her average score whereas Holly only scored 2.5 points above her average score. (this was calculated via z-scores)
To find who performed better relative to their average, we calculated the z-scores of both players. Juanita's score was 3.2 standard deviations above her mean, whereas Holly's was 2.5 standard deviations above her mean, making Juanita's performance relatively better.
To answer this question, we need to find how many standard deviations each player's score deviates from their respective means. This is referred to as the z-score. The z-score is calculated using the formula (X - μ) / σ, where X is the score, μ is the mean score and σ is the standard deviation.
For Holly, her z-score would be (25 - 20) / 2 = 2.5. This means Holly's score was 2.5 standard deviations above her mean score.
For Juanita, her z-score would be (16 - 12) / 1.25 = 3.2. This means Juanita's score was 3.2 standard deviations above her mean score.
Since Juanita's z-score is higher than Holly's, Juanita's score is better relative to her average number of points per game.

The area of the irregular polygon in the sketch is: D. 40.5 cm².
To find the area of an irregular polygon, decompose the polygon into known shapes. Find the area of each shape and add all together.
Thus:
The irregular polygon is made up of a rectangle and a triangle.
Area of the irregular polygon = area of rectangle + area of triangle.
= length × width + 1/2(base × height)
Length = 12.5 cm
Width = 3 cm
Base = 3 cm
Height = 2 cm
Area of the irregular polygon = 12.5 × 3 + 1/2(3 × 2)
= 40.5 cm²
