Answer:

option (D) 625 bp

Step-by-step explanation:

Data provided in the question :

Number of different bases, B = 5

Number of base recognition sequence, n = 4

Frequency of all 5 nucleotides are same

Now,

The RNA will be deduced using the formula as:

⇒ Bⁿ

on substituting the respective values, we get

⇒ 5⁴

or

⇒ 625 bp

Hence, the correct answer is option (D) 625 bp

Part A: Explain why x = 5 makes 4x - 1 3 19 true but not 4x - 1 19
Olenka [21]

Answer:

<em>Part A</em>: Explain why x = 5 makes 4x - 1 ≤ 19 true but not 4x - 1 < 19

<em>Part B: x=9</em>

Step-by-step explanation:

<u>Part A</u>: Because the first one is less than or equal to 19 and the other is just      less than.

x = 5

TRUE:   4x - 1 ≤ 19    =    20-1 ≤ 19    =    19 ≤ 19  

             19 is less than or equal to 19 so its true

FALSE:  4x - 1 < 19    =    19 < 19  

              19 is not greater than 19

<u>Part B:</u>  

5x + 2 = 47  subtract 2 from both sides

5x = 45  divide both sides by 5

x = 9

To check we can plug it back in

5x + 2 = 47

5(9) + 2 = 47

45 + 2 = 47

47 = 47

TRUE

The mayor of a town has proposed a plan for the annexation of a new community. A political study took a sample of 10001000 voter
Reil [10]

Answer:

We accept H₀

p-value = 0,1618

Step-by-step explanation:

We are going to solve a one tail proportion-test ( right tail)

We assume Normal distribution

Sample population 1000

Political strategist to test  wants to test:

Null hypothesis                             H₀           p = p₀       or   p = 26 %

Alternate hypothesis                    Hₐ           p > p₀        or  p > 26%

We assume CI  90 % then

α = 10 %     α = 0,1    and  z score for α = 0,1  is critical value

z = 2,32          ( note  2,32 is z score for α = 0,1017 "good approximation")

To compute z(s)

z(s)  =  ( p -p₀ ) / √ p₀q₀/n

z(s)  =  ( 0,29 - 0,26 ) /√ 0,26*0,74/1000

z(s)  = 0,03 / 0,014

z(s) = 2,14

We compare z(s) and z(c)

z(s) < z(c)

2,14 < 2,32

z(s) is in the acceptance region we accept H₀

The p-value for z(s) is from z-table

p-value = 0,1618

A person standing 213 feet from the base of a church observed the angle of elevation to the church's steeple to be 33 ∘ .
solniwko [45]

Complete Question

A person standing 213 feet from the base of a church observed the angle of elevation to the church's steeple to be 33 ∘. Find the height of the church

Answer:

138.3 ft

Step-by-step explanation:

We solve this question above using using the Trigonometric function of Tangent.

tan θ = Opposite/Adjacent

Where:

Opposite = Height of the church = x

Adjacent = Distance for the base of the church = 213ft

Angle of elevation θ = 33°

Hence:

tan 33 = x /213 ft

Cross Multiply

x = tan 33 × 213 ft

x = 138.32381735 ft

x = Opposite Approximately = 138.3 ft

Therefore, the height of the church = 138.3 ft

Lindsay is 5 years younger than Mark. Seven years ago, the sum of their ages was 31.
Rashid [163]

Answer:

The present age of Mark is 25 years.

And present age of Lindsay is  20 years.

Step-by-step explanation:

Let us assume:

The present age of Lindsay = l

The present age of Mark = m

⇒ Age of Lindsay seven years ago =  (l -7) years

and Age of Mark seven years ago =  (m -7) years

According to question:

Lindsay is 5 years younger than Mark    ⇒   l = m  - 5

Seven years ago, the sum of their ages was 31  ⇒  (l-7) + (m -7)  = 31

So, the given set of equation are:

l = m  - 5    .........  (1)

(l-7) + (m -7)  = 31

⇒ ((m - 5) -7) + (m -7)  = 32  (from (1)

or, m -12 + m - 7  = 31

or, 2m = 31 + 19 = 50

⇒ m = 50 / 2  = 25, or m  = 25

Hence,the present age of Mark = 25 years

So,the present age of Lindsay = 25 - 5 = 20 years

URGENT!! ILL GIVE<br> BRAINLIEST!!!! AND 100 POINTS!!!!
Harlamova29_29 [7]

Answer:

To find the perimeter of the triangle, you would add p + m + n. To find the area of the triangle you would use (p x m) /2. To find a missing side of the triangle, given that it is a right triangle, you would use p^2 + m^2 = n^2
