From the test scores given:
<span> 42 45 50 57 60 63 66 70 73 78 85 87 90 94 95
splitting the values into 3 sets:
</span><span> (42 45 50 57 60 )(63 66 70 73 78)( 85 87 90 94 95)
from the first set we select the median:
</span>42 45 50 57 60
the median is 50
thus the first quartile will be 50

Answer:

41.8 years

Step-by-step explanation:

From

A = P(1+r/n)^{nt}

A= 39000

r = 10.5%

P = $ 485

n=12

t = the unknown

t= [ ln(A) - ln(P) ] / n[ln(1 + r/n)]

t= ln 39000 - ln 485/ 12[ln(1+0.105/12)]

t= 10.57 - 6.18/0.105

t= 41.8 years

X - 35 &gt; 15 i need answer IMEDIATLEY
SIZIF [17.4K]

I'm assuming you want us to solve this inequality for x, since the question wasn't too clear on that.

x - 35 > 15

Add 35 to both sides to remove the "-35" on the left side so we can isolate the x

x-35+35>15+35

x>50

The solution to this inequality is x>50. Let me know if you need any clarifications, thanks!
