Answer:
1047 cards
Step-by-step explanation:
3x349=1047 3x300=900 3x40=120 3x9=27 900+120+27=1047
This is a vertical parabola, because (x-1)².
Vertex of the parabola (1,1).
So line symmetry is x=1.
Answer:
The value is
Step-by-step explanation:
From the question we are told that
The population proportion is
The sample size is n = 563
Generally the population mean of the sampling distribution is mathematically represented as
Generally the standard deviation of the sampling distribution is mathematically evaluated as
=>
=>
Generally the probability that the proportion of persons with a college degree will differ from the population proportion by less than 5% is mathematically represented as
Here is the sample proportion of persons with a college degree.
So
Here
=>
=>
=>
From the z-table the probability of (Z < 2.37 ) and (Z < -2.37 ) is
and
So
=>
=>
=>
The angular size of Mars, as seen from the Earth, when it was closest to the Earth is 25 arcseconds.
<h3>What is angular size?</h3>
It should be noted that angular size is the object's apparent size as seen from an observer on Earth.
At its closest approach, the angular size of Mars is 25 arcseconds. This was known through the use of a telescope.
