1,263,000,000-15,250,000=1,247,750,000
Answer:
(a) $6550
(b) $1511.54
Step-by-step explanation:
(a) You can solve the equation
... 12 × (monthly salary) = $78,600
by dividing both sides of the equation by 12.
... (monthly salary) = $78,600/12 = $6,550
(b) You know there are 52 weeks in a year, so you know that ...
... 52 × (weekly salary) = $78,600
... (weekly salary) = $78,600/52 ≈ $1,511.54 . . . . . . . divide by 52
Answer:
Probability =0.9898
Step-by-step explanation:
Given that, mean = 4 = 300 standard deviation = 70 n = 100 PT = H = 128 oT = 0 / V n = 70/ v 100 = 7 a) within 6 = 300 ±6 = 294, 306 P(294< ī < 306) = P[(294 - 300) 7 < (ĩ -H ï) / o ĩ < (306 300) /7)] = P(-0.86 < Z < 0.86) = P(Z < 0.86) - P(Z < -0.86) Using z table, 0.8051 - 0.1949 %3D %3D %3D = 0.6102 Probability = 0.6102 a) within 18 = 300 t 18 = 294, 318 P(294< ī < 306) = P[(282 - 300) / 7< (ã -H i) / oī< (318 - 300) /7)] = P(-2.57 < Z< 2.57) = P(Z < 2.57) - P(Z < -2.57) Using z table, =0.9949 - 0.0051 =0.9898 Probability =0.9898
Remember that complementary angles add to 90 degrees.
so therefor, you can find the complement of m<A by solving
90 - 77 = A
A = 13 degrees
^^^ This explains the second part.
The compliment of a compliment can be found by subtracting the known compliment from 90 :)
To find the answer to this question you would just add 10 to 70 and multiply by 4 and your answer would be 320
