The mean annual incomes of certified welders are normally distributed with the mean of $50,000 and a standard deviation of $2,00

SCORPION-xisa [38]

Answer:

Therefore, for the case above; the Alternative hypothesis is;

H1: is not equal to $50,000.

H1: ≠ $50,000.

Step-by-step explanation:

The null hypothesis (H0) tries to show that no significant variation exists between variables or that a single variable is not different than its mean.

While an alternative Hypothesis (Ha) attempt to prove that a new theory is true rather than the old one. That a variable is significantly different from the mean.

Therefore, for the case above; the Alternative hypothesis is;

H1: is not equal to $50,000.

H1: ≠ $50,000.

you are planting roses

you started at 12 noon

at 3pm, you have 80 roses left

at 6pm, you have 20 roses left

if you planted roses at a constant rate, how many roses did you start with?

so we can find the slope of this linear function as (20roses-80roses)/(6pm-3pm)=60roses/3hrs=-20roses/hr

your quantity goes down by 20 roses per hour (you plant 20 per hour)

r=-20t+?

find ?, the number of roses when t=0

at 3pm yo have 80 roses

80=-20(3)+?

80=-60+?

140=?

you had 140 roses intiailly

the town polpulationn grows at an exponential rate

the town was founded in 2000

in 2010, the town's population was 1000

in 2015, the town's populationw as 2000

find intial polpulation

exponential can be modeled by $y=ab^t$ where y=population, t=time and b and a are constants (a=initial population)

we are given that after 10 years (2010), y=102400

after 15 years, (2015), y=3276800

so

$102400=ab^{10}$ and $3276800=ab^{15}$

divide the 2nd by the first equation, remembering our exponential properties like $\frac{x^a}{x^b}=x^{a-b}$

$32=b^{5}$

take 5th root of both sides

$b=2$

subsitute back

$102400=ab^{10}$

$102400=a(2)^{10}$

$102400=1024a$

$100=a$

the intial population is 100 people
