Answer:

D, 94

Step-by-step explanation:

Angles of a triangle add up to 180 degrees.  180 - 29 - 65 = 86 Angles 1 and 2 add up to 180 degrees.  86 = 2  180 - 86 = 94 94 = 1

Solution :

Here, we have 5 trails that corresponds to the 5 times the binary symbol is sent. On each trail, success is said to occur when the binary symbol is received correctly. The probability of a success is p = 1 - q = 0.9 and q = 0.1

Now if the 0 is being transmitted, then the 0 is sent 5 number of times and then we call the decoding a 0 success. Let the repeated transmission are independent. In this case, we have 5 trails. Let each repeated bit the receiver decodes as 1 a success, using the binomial probabilities. We using the [tex]$S_{k,5}$[/tex] to denote an event of [tex]$k$[/tex] successes in the 5 trails, then the probability k are decoded at the receiver is:

[tex]$P[S_{k,5}]=\binom{5}{k}p^k(1-p)^{5-k}$[/tex]

           [tex]$=\binom{5}{k}(0.9)^k(1-0.9)^{5-k}$[/tex]

           [tex]$=\binom{5}{k}(0.9)^k(0.1)^{5-k}$[/tex]    

Here, k = 1, 2, 3, 4, 5

The probability of the transmitted bit to be decoded correctly is:

[tex]$P[C]=P[S_{5,5}]+P[S_{2,5}]$[/tex]

         [tex]$=\binom{5}{3}(0.9)^5(0.1)^{0}+\binom{5}{4}(0.9)^4(0.1)^1$[/tex]

         [tex]$=(0.9)^5+5(0.9)^4(0.1)^1$[/tex]

         = 0.91854

The probability that the deletion occurs is

[tex]$P[D]=P[S_{3,5}]+P[S_{2,5}]$[/tex]

          [tex]$=\binom{5}{3}(0.9)^3(0.1)^{2}+\binom{5}{2}(0.9)^2(0.1)^3$[/tex]

         [tex]$=10(0.9)^3(0.1)^2+10(0.9)^2(0.1)^3$[/tex]

         = 0.081

The probability of an error is

[tex]$P[E]=P[S_{1,5}]+P[S_{0,5}]$[/tex]

          [tex]$=\binom{5}{1}(0.9)^1(0.1)^{4}+\binom{5}{0}(0.9)^0(0.1)^5$[/tex]

         [tex]$=5(0.9)^1(0.1)^4+(0.1)^5$[/tex]

         = 0.00046

Answer:

Step-by-step explanation:

7a - 4a

a = 8

so

7(8) - 4(8)

56 - 32 = 23

FINALLY! Someone asks for a step-by-step! TYSM!

Since a=8, we ae going to replace the a variables with 8.

7(8)-4(8)

7x8=56

4x8=32.

Now we subtract.

56-32=24.

Answer:

25

Step-by-step explanation:

c to d is 5 to 4

5x5=25

fffff

Answer:

25

Step-by-step explanation:

We need to divide 20 by 4 to see how much 1 equals in this problem.

20÷4=5

5 equals 1

Now we add 5 to 20 because the ratio is 5:4.

20+5=25

Our answer is 25.

Answer:

Part A)

784 feet in the air (after five seconds).

Part B)

After 12 seconds.

Step-by-step explanation:

The height h (in feet) of a rocket t seconds after being fired is modeled by the function:

[tex]h(t)=-16t^2+160t+384[/tex]

Part A)

We want to find the rocket's maximum height.

Since our function is a quadratic, the maximum height will occur at its vertex. The vertex of a quadratic is given by:

[tex]\displaystyle \Big(-\frac{b}{2a}\, f\Big(-\frac{b}{2a}\Big)\Big)[/tex]

In this case, a = -16, b = 160, and c = 384.

So, the vertex occurs at:

[tex]\displaystyle t=-\frac{160}{2(-16)}=\frac{160}{32}=5\text{ seconds}[/tex]

The maximum height is reached after five seconds.

Then the maximum height is:

[tex]h(t)_\text{max}=h(5)=-16(5)^2+160(5)+384=784\text{ feet}[/tex]

Part B)

When the rocket reaches the ground, its height h above the ground will be 0. Hence:

[tex]h(t)_\text{ground}=0=-16t^2+160t+384[/tex]

Solve for t. We can first divide both sides by -16:

[tex]t^2-10t-24=0[/tex]

Factor:

[tex](t-12)(t+2)=0[/tex]

Zero Product Property:

[tex]t-12=0\text{ or } t+2=0[/tex]

Solve for each case:

[tex]t=12\text{ or } t=-2[/tex]

Time cannot be negative. Hence, our only solution is:

[tex]t=12\text{ seconds}[/tex]

The rocket reaches the ground 12 seconds after it is fired.

2.2n+7

Step-by-step explanation:

for number 1.you are multiplying 3 and n which gives you 3n but 2 you cant because it dosent have a variable to times with it says plus instead of times.

and for number 2 it the same thing 2 times n equals 2n + 7 is 2n + 7 .

If this doesnt help then im sorry but this is how i know and yeah have a wonderful day.

Step-by-step explanation:

she needs altogether 2 2/4.

that is 2 wholes and 2/4 fraction.

if we consider using 1/4 cup, 1 whole is made of four quarter cups.

Therefore 2 wholes require eight quarter cups. then theres a remaining fraction of 2/4 which is equivalent to two quarter cups.

1/4 + 1/4 = 2/4. therefore altogether  8 + 2 = 10 of the 1/4 cups are required for the recipe.

10 of 1/4 cups are needed

Answer:

Step-by-step explanation:

a/b=7/5

a=7b/5

a+b=36, using 7b/5 for a we have

7b/5+b=36

7b/5+5b/5=36

12b/5=36

12b=180

b=15, and since a=7b/5

a=7(15)/5

a=21

So the numbers are 21 and 15
