Step-by-step explanation:
Arrow JK=360-54-130-110=66
arrow MK=66+54=120
Angle L=120/2=60
3a=60
a=30
Answer:
The bird dove 44 feet.
Step-by-step explanation:
If the bird starts 37 feet above the ocean and dives from its position to 7 feet below the ocean, the you just add the two numbers and get its total dive.
To draw it draw a graph that goes past to +37 and past -7, then draw a bar representing the birds dive from +37 to -7. The X axis would be time, and the Y axis is the bird's height relative to the surface of the water.
So do 50 times 12 is 600. So all you have to do is divide 144 by 600 which is .24 so she already swam 24%
Answer:
Therefore, the number of female statistics student ages that must be obtained in order to estimate the mean age of all female statistics student is 3625 female statistics student
Step-by-step explanation:
Here, we have
Where:
n = Required sample size
σ = Standard deviation = 18.3
E = Margin of error = 1/2 year
= Critical score from the confidence level = 1.645
Therefore,
Therefore, the number of female statistics student ages that must be obtained in order to estimate the mean age of all female statistics student = 3625 female statistics student.
Answer:
120 deg
Step-by-step explanation:
The sum of the measures of the interior angles of a quadrilateral is 360 deg.
2t + 2t + t + t = 360
6t = 360
t = 60
m<Z = 2t = 2(60) = 120
Answer: 120 deg
