Answer:
4.397 * 10⁹
Step-by-step explanation:
(3.700 * 10⁹) + (6.970 * 10⁸) = (3.700 * 10 * 10⁸ ) + (6.970 * 10⁸)
= (37.00 * 10⁸) + (6.970 * 10⁸)
= (37.00 + 6.970) * 10⁸
= 43.97 * 10⁸
= 4.397 * 10 * 10⁸
= 4.397 * 10⁽¹⁺⁸⁾
= 4.397 * 10⁹
Answer:
Last option is the correct choice.
Step-by-step explanation:
Convert the mixed numbers into fraction and apply the rate formula.
Rate = Change / Unit Time
= 12 1/4 ÷ 3 1/2
= 49/4 ÷ 7/2 (Answer matching with the last option)
= 49/4 x 2/7 (Inverting the second fraction)
= 7/2
= 3 1/2
The rate of change per hour is 3 and a half degrees in temperature.

Step-by-step explanation:
Answer:
2.33
Step-by-step explanation:
We shall use the z distribution because we know the population standard deviation.
The margin of error formula is given by:
The z-value for 98% confidence interval is 2.326.
The sample size is n=25.
The population standard deviation is is
We substitute the values into the formula to get:
Evaluate square root:
Simplify:
