Step-by-step explanation:
A(t)=P(e^(rt))
Insert the values as follows:
The equation for "continual" growth (or decay) is A = Pe^(rt), where "A", is the ending amount, "P" is the beginning amount (principal, in the case of money), "r" is the growth or decay rate (expressed as a decimal), and "t" is the time (in whatever unit was used on the growth/decay rate).
34820=P(e^((.78)(5)))
34830=P(49.4024)

Suppose that 55% of people own dogs. If you pick two people at random, what is the probability that they both own a dog?
Answer:
The probability to one person to be a dog owner is p=0.56 (because 56% of people own dogs) and the probability that one person is not dog owner is q=1-p=1-0.56=0.44.
Step-by-step explanation:
Choosing two people at random, there are such possibilities:
1. both are dog owners;
2. first owns a dog, second not;
3. first hasn't dog, second owns a dog;
4. both haven't dogs.
Answer: if you pick two people at random the probability that they both own a dog is 0.3136.
Hope this helps! :))
The Probability that they both own a dog is 0.3025.
Here,
55% of people own dogs.
If pick two people at random,
Then we have to find the probability that they both own a dog.
What is Probability?
Probability is defined as the likelihood of something occurring or the chance of something happening.
Now,
55% of people own dogs.
Hence, the probability that they both own a dog = 55% * 55%
= 0.55 * 0.55
= 0.3025
So, The probability that they both own a dog is 0.3025.

Select all of the given trigonometric equations that are true statements. sin(180°) = cos(0°) cos(74°) = sin(16°) sin(20°) = cos(70°) sin(A°) = cos(90° - A°) sin(A°) = cos(180° - A°) cos(140°) = sin(40°)
Answer:
Cos 74°= Sin 16°
Sin 20°= Cos 70°
Sin A°=Cos (90°- A°)
Step-by-step explanation:
This is because the three pairs are complementary i.e they add up to 90° and in trigonometric ratios, complementary ratios are equal.

Answer:
x = 14.4
Step-by-step explanation:
First of all, the triangle has three sides, so let's use hero's formula to find the area.
A = √[p(p - a)(p - b)(p - c)]
Where;
a, b and c are the 3 given sides of the triangle and;
p = (a + b + c)/2
p = (18 + 30 + 24)/2
p = 72/2
p = 36
Thus;
A = √(36(36 - 18)(36 - 30)(36 - 24))
A = √46656
A = 216 Sq.units
Now, we also know from general formula of a triangle that;
A = ½bh
Where;
b is base and h is height
In the given image;
b = 30
h = x
Thus;
½ × 30 × x = 216
Rearranging, we have;
x = 216 × 2/30
x = 14.4
An equivalent equation has been written by multiplying the second equation by 2.
4x – 9y = 7 → 4x – 9y = 7
2(–2x + 3y = 4) → –4x + 6y = 8
What is the solution to the system?
a: (-19/2, -5)
b: (-5, -19/2)
c: (-15/2, -11/3)
d: -19/10, 1/15)
Answer:
(-19/2, -5)
Step-by-step explanation:
Given the two equivalent equations
4x – 9y = 7 .... 1
–4x + 6y = 8 ....2
Adding both equations
-9y + 6y = 7+8
-3y = 15
y = -15/3
y = -5
Substitute y = -5 into 1
From 1; 4x - 9y = 7
4x - 9(-5) = 7
4x + 45 = 7
4x = 7 - 45
4x = -38
x = -38/4
x = -19/2
Hence the solution is (-19/2, -5)

y = -3/4x - 7
A study was performed to investigate whether teens and adults had different habits when it comes to consuming meat-free meals. In particular, the researchers were interested in the relationship between p1, the proportion of teens who would report eating at least one meat-free meal in the past week, and p2, the proportion of adults who would report eating at least one meat-free meal in the past week. A random sample of 875 teens and a separate random sample of 2,323 adults found that 555 of the teens and 1,601 of the adults reported eating at least one meat-free meal in the past week. The conditions for inference were checked and verified. What is the correct set of hypotheses the researchers should test in this scenario
Answer:
H₀ should be rejected at CI 95% .
Then the proportion of adults with 95 % CI is bigger than the proportion of teen
Step-by-step explanation:
From adult sample:
n₂ = 2323
x₂ = 1601
p₂ = 1601 / 2323 p₂ = 0,689 or p₂ = 68,9%
From teen sample:
n₁ = 875
x₁ = 555
p₁ = 555/ 875 p₁ = 0,634 or p₁ = 63,4
Values of p₁ and p₂ suggest that the proportion of adults consuming at least one meat free meal per week is bigger than teen proportion.
To either prove or reject the above statement we have to develop a difference of proportion test according to:
Hypothesis test:
Null Hypothesis H₀ p₁ = p₂
Alternative Hypothesis Hₐ p₂ > p₁
So is a one-tail test to the right
We can establish a confidence interval of 95 % then α = 5 %
or α = 0,05
As the samples are big enough we will develop a z test
Then z(c) for α = 0,05 from z table is z(c) = 1,64
To calculate z(s)
z(s) = ( p₂ - p₁ ) / √p*q* ( 1/n₁ + 1/n₂ )
where p = ( x₁ + x₂ ) / n₁ + n₂ p = 555 + 1601 / 875 + 2323
p = 2156/3198 p = 0,674
and q = 1 - 0,674 q = 0,326
z(s) = ( 0,689 - 0,634 ) / √0,674*0,326 ( 1/875 + 1 / 2323
z(s) = 0,055/ √ 0,2197 ( 0,00114 + 0,00043)
z(s) = 0,055/ √0,2197* 0,00157
z(s) = 0,055/ √ 3,45*10⁻⁴
z(s) = 0,055 / 1,85*10⁻²
z(s) = 5,5/1,85
z(s) = 2,97
Comparing z(s) and z(c) z(s) > z(c)
Then z(s) is in the rejection region we reject H₀.
We can claim that the proportion of adult eating at least one meat-free meal is bigger than the proportion of teen
