Answer:
99.7%
Step-by-step explanation:
Empirical rule formula states that:
• 68% of data falls within 1 standard deviation from the mean - that means between μ - σ and μ + σ.
• 95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ.
• 99.7% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ.
From the question, we have mean of 98.18 F and a standard deviation of 0.65 F
The approximate percentage of healthy adults with body temperatures between 96.23 F and100.13 F is
μ - 3σ
= 98.18 - 3(0.65)
= 98.18 - 1.95
= 96.23 F
μ + 3σ.
98.18 + 3(0.65)
= 98.18 + 1.95
= 100.13 F
Therefore, the approximate percentage of healthy adults with body temperatures between 96.23 F and 100.13 F which is within 3 standard deviations of the mean is 99.7%
Se a cada 25 minutos ele marca 15 pontos, para saber quantos pontos ele marcou em 200 minutos, basta dividir 200 por 25, que dá 8. Depois multiplicamos 8 por 15, que dá 120. Sendo assim, marcou 120 pontos em 200 minutos.
Resposta: Ele marcou 120 pontos.
The correct answer is 45ft(along the ground)
Explanation:
It is making the right angled triangle as one half is 28 feet tall(vertically straight); the other half which fell over some distance is the hypotenuse. To find its length:
Hypotenuse = 81 - 28 = 53
Now that we have hypotenuse and the vertical length (perpendicular), we can find the base( along the ground) using Pythagoras theorem:
c^2 = a^2 + b^2
c = hypotenuse
a = perpendicular
b = base
53^2 = 28^2 + b^2
b = 45ft (along the ground)
Answer:
$2000
Step-by-step explanation:
1,000 g would be = 1 Kg so it would be 25 Kg
And 25 X 80 = 2000
Area of rectangle prism, to find the answer, use this formula: 2 x ( h x d + h x w + d x w )
So it would look like this: 2 x ( 12 x 6 + 12 x 7 + 6 x 7 ) = 396
I would say the answer is B. 396 in2
Hope I helped ; )
