Answer:
I'm not completely sure but I think it's 350
Step-by-step explanation:
5/6 is .8333 then you multiply .8333 by 420 and you get 350
hlp plz this is really hard
Answer:
16 =2^4
Step-by-step explanation:
16
16 = 4*4
but 4 is not prime
4 = 2*2
16 = 2*2*2*2
Rewriting with exponents
16 =2^4
Answer:
→ Prime factorization of 16 :
least $200?
Answer:
27 hours
Step-by-step explanation:
So t is going to represent time. $8t is equivalent to how much she makes for t amount of time. Being she is already down $16 for the gas, we have to take that into consideration that she must earn that back. Set up:
$8t - $16 = $200
Add like terms to get:
$8t = $216
Now solve for t by dividing both sides by $8.
t = 27 hours
employed by the federal government.
μ2: The mean training time for the population of airport security personnel
employed by private security companies.
The goal of the statistical analysis is to determine whether the sample data support the hypothesis that average training time for government-employed security personnel is higher than those employed by private security companies.
1. What is the null hypothesis H0?
Select one:
a. μ1- μ2 <= 0
b. μ1- μ2 < 0
c. μ1- μ2 =/ 0
d. μ1- μ2 > 0
2. What is the alternative hypothesis Ha?
Select one:
a. μ1- μ2 > 0
b. μ1- μ2 <= 0
c. μ1- μ2 = 0
d. μ1- μ2 >= 0
Answer:
1.a. H₀: μ₁ - μ₂ ≤ 0
2.b. H₁: μ₁ - μ₂ > 0
Step-by-step explanation:
Hello!
The objective is to compare the average training time for two groups of airport security personnel.
Group 1: Security personnel that works for the federal government
n= 12
X[bar]= 72 hs
S= 8hs
Group 2: Security personnel from private companies
n= 16
X[bar]= 65.4 hs
S= 12.3 hs
The goal of the analysis is to test if the average training time for government-employed security personnel is higher than those employed by private security companies, symbolically: μ₁ > μ₂
The null and alternative hypotheses are complementary and exhaustive.
The null hypothesis always represents the "no change situation" and therefore always carries the = symbol. Generally, the researcher's claim is stated in the alternative hypothesis.
With all this in consideration, the hypotheses for this experiment are:
H₀: μ₁ ≤ μ₂
H₁: μ₁ > μ₂

Answer:
24.5
Step-by-step explanation:
24 = 24
1/2 -->
convert to a decimal => 1 divided by 2
0.5
24+0.5 = 24.5
Hope this helps!
The factored expression of the expression x^3 + 4x^2 +5x + 20 is (x^2 + 5)(x + 4)
The expression is given as:
x^3 + 4x^2 +5x + 20
Group the expression into two
(x^3 + 4x^2) + (5x + 20)
Factorize each group
x^2(x + 4) + 5(x + 4)
Factor out x + 4
(x^2 + 5)(x + 4)
Hence, the factored expression of the expression x^3 + 4x^2 +5x + 20 is (x^2 + 5)(x + 4)
