Answer:
£1999.85
Step-by-step explanation:
A = P(1 + rt)
Where:
A = Amount after t years
P = Initial amount invested = £1850
r = Interest rate = 2.7%
t = Time in years = 3 years
Calculation:
First, converting R percent to r a decimal
r = R/100 = 2.7%/100 = 0.027 per year.
Solving our equation:
A = £1850(1 + (0.027 × 3))
A = £1999.85
Therefore, Brian will have £1999.85 after 3 years.
Answer:
The events a) and c) are mutually exclusive.
Step-by-step explanation:
a) This is mutually exclusive, each card has a unique value between 2 and 10, or it is a jack, queen, king, or an Ace. A single card cant have two different values at the same time.
b) This is not mutually exclusive, since you can get a king of clubs. Each card can have any combination of one suit and one value.
c) A face card is either a Jack, a Queen or a King, it is not an Ace. For the same argument of a), a card cant have two different values, therefore this event is mutually exclusive.
d) This is not mutually exclusive, since a card can have any suit independently of the value it has (same argument than b), therefore, a card can be a face card and a spade at the exact time.
Therefore, events a and c are mutually exclusive.
Because when you know the techniques to know when it's rational, you'll automatically know when it isn't.
Answer:
<h3>B. 4 × 8.5 = 34</h3>
Step-by-step explanation:
The formula for calculating the perimeter of the square patio is expressed as;
P = 4L
L is the length of each side of the square patio
Given
L = 8.5 feet
Required
Perimeter in feet of Rocio's patio
Substitute the given parameter into the formula;
Perimeter = 4 * 8.5
Perimeter = 34ft²
Option B is correct.
B Athlete Median = 61 IQR = 2 athlete shows the most consistency in her 400- meter race because her Interquartile range variability is less compare to the others.
Step-by-step explanation:
- Median is the mid-point of the data.
- Median takes average of 25%, 50%(Median) and 75% of data.
- Box plot is an easier way to understand Mean and Median.
- Interquartile range helps in finding the variability.
- Q3(Third quartile) - Q1(First quartile) gives variability.
- The IQR number is higher it is high variability.
- Median comes in descriptive statistics, It helps in describing data.
- Median helps in finding the outliers and skewness of the data.
