Answer:
D
Step-by-step explanation:
189 boys is 54%
x is 46%(100-54)
Cross multiply:
189*46%=54%*x
86.94=0.54x
x=161
189 boys 161 girls

Complete question :
A student forgets to study for an exam consisting of ten multiple choice questions, each with three possible answers. Instead, the student will have to randomly guess, so that there is a 1 3 probability of getting any arbitrary question right. If 6 or more correct answers is a passing score, what is the probability of passing
Answer:
0.07656
Step-by-step explanation:
Given that:
P(correct guess) = 1/3 ; p= 0.33333
Number of questions /trials = 10
P(x ≥ 6) = p(6) + p(7) + p(8) +... + p(10)
This is the sum of the probabilities of getting exactly 6, 7, 8, 9 or 10 questions.
Using the binomial probability calculator to save computation time :
P(x ≥ 6) = 0.07656

A total of $10,000 is invested at an annual interest rate of 3%. Find the balance after 5
years if the interest is compounded a) quarterly and b) continuously.
Answer:
Step-by-step explanation:
We will need 2 different equations for this problem. For compounding a certain number of times a year, the formula is
[tex]A(t)=P(1+\frac{r}{n})^{nt}[/tex] so let's do that first. Filling in we get
[tex]A(t)=10000(1+\frac{.03}{4})^{(4)(5)[/tex] and simplifying a bit gives us
[tex]A(t)=10000(1+.0075)^{20}[/tex] and a bit more,
[tex]A(t)=10000(1.0075)^{20}[/tex] and then
A(t) = 10000(1.161184142) so
A(t) = 11611.84
Then for the compounding continuously, the formula is
[tex]A(t)=Pe^{rt[/tex]
[tex]A(t)=10000e^{(.03)(5)}[/tex] and simplify a bit to\
[tex]A(t)=10000e^{.15}[/tex] Now raise e to the power of .15 on your calculator to get
A(t) = 10000(1.161834243) so
A(t) = 11618.34

Step-by-step explanation:
Use the figure to find the measure of the angle.Explain your reasoning.
angle2=180-152=28
angle3=28
angle4=152
angle5=152
angle6=28
angle7=28
angle8=152
The values of the marked angles: angle 2, angle 3, angle 4, angle 5, angle 6, angle 7, angle 8 are 28°, 28°, 152°, 152°, 28°, 28°, 152°.
What is an angle?When two lines or rays meet at a point, then the geometrical figure is formed, is called an angle.
Given, angle 1 = 152°
We know, angle 1 + angle 2 is 180°. (supplementary angles)
Therefore, angle 2 = (180° - 152°) = 28°.
Again, angle 2 = angle 3. (opposite angles)
Therefore, angle 3 = 28°.
Similarly, angle 1 = angle 4
Therefore, angle 4 = 152°.
Now, angle 1 = angle 5 (corresponding angle)
Therefore, angle 5 = 152°.
Now, angle 2 = angle 6 (corresponding angle)
Therefore, angle 6 = 28°.
Now, angle 3 = angle 7 (corresponding angle)
Therefore, angle 7 = 28°.
Now, angle 4 = angle 8 (corresponding angle)
Therefore, angle 8 = 152°.
