Answer: 2 is less than 5 so when she rounded she ended up with 4 feet and the doctors didn’t round
Step-by-step explanation:
I think this is correct
The number that was left out is 70.
<h3>What is the number that was left out?</h3>
Average is the sum of a set of numbers divided by the total numbers in the data set.
Average = sum of numbers / total numbers
- Sum of numbers when there are 8 numbers = 56 x 8 = 448
- Sum of numbers when there are 7 numbers = 54 x 7 = 378
- Difference = 448 - 378 = 70

Answer:
0.1
Step-by-step explanation:
Solving using empirical rule formula
95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ .
Hence, the lower bound 95% =
μ - 2σ
Mean = 0.2
Standard deviation of 0.05
= μ - 2σ
= 0.2 - 2(0.05)
= 0.2 - 0.1
= 0.1
The lower bound is 0.1
Answer:
m∠1=80°, m∠2=35°, m∠3=33°
Step-by-step explanation:
we know that
The sum of the interior angles of a triangle must be equal to 180 degrees
step 1
Find the measure of angle 1
In the triangle that contain the interior angle 1
∠1+69°+31°=180°
∠1+100°=180°
∠1=180°-100°=80°
step 2
Find the measure of angle 2
In the small triangle that contain the interior angle 2
∠2+45°+(180°-∠1)=180°
substitute the value of angle 1
∠2+45°+(180°-80°)=180°
∠2+45°+(100°)=180°
∠2+145°=180°
∠2=180°-145°=35°
step 3
Find the measure of angle 3
In the larger triangle that contain the interior angle 3
(∠3+31°)+69°+47°=180°
∠3+147°=180°
∠3=180°-147°=33°
There is a common denominator of 12 among those fractions.
