in how many ways can 7 of 10 mice can be arranged in a row for geentics experiments?

Answers

Answer 1

Answer:

Number of arrangements is 604800

Step-by-step explanation:

Given

[tex]Mouse = 10[/tex] --- Total

[tex]Mouse = 7[/tex] --- Arrangement

Required

Determine the number of ways

Since, it is an arrangement, then we make use of the following permutation formula to answer this question.

[tex]^nP_r = \frac{n!}{(n-r)!}[/tex]

Where

[tex]n = 10[/tex]

[tex]r = 7[/tex]

So:

[tex]^nP_r = \frac{n!}{(n-r)!}[/tex]

[tex]^{10}P_7 = \frac{10!}{(10-7)!}[/tex]

[tex]^{10}P_7 = \frac{10!}{3!}[/tex]

[tex]^{10}P_7 = \frac{3628800}{6}[/tex]

[tex]^{10}P_7 = 604800[/tex]

Hence, number of arrangements is 604800

Jeremy is making a healthy ice cream using only ripe bananas and peanut butter, the recipe makes 4 servings and calls for a ratio of 5

Tablespoons

Answers

Answer:

can u show me a pic of the question so it is easier

The healthy ice cream Jeremy is making has 30 bananas and requires 18 tablespoons of peanut butter.

What is a ratio?

The ratio describes the amount of quantity in simplest form, a:b can be written as 'a/b' for convenience.

Given the healthy ice cream, Jeremy is making requires 5 bananas and 3 tablespoons of peanut butter.

From the given question itself, we can conclude that bananas and peanut butter are in direct proportion as the increase in one quantity will result in an increase of another quantity and we can write this in proportion and let the no. of tablespoons of peanut butter requires for 30 banans is x.

∴ 5 : 3 : : 30 : x.

Or

5/3 = 30/x.

5x = 90.

x = 18.

So, Jeremy needs 18 tablespoons of peanut butter for the 30 bananas he has.

A positive correlation between the number of homework assignments completed and the grade on the examA positive correlation between the temperature in a canyon in the early spring and the number of snakes seen by hikers.

When are relationships causal?

A relationship is causal when one variable has a direct effect on another variable. For example, the number of assignments completed would have an effect on the grade on an exam because as a students compeletes his assingment he becomes more familiar with the course.

Positive correlation means that the two variables have a positive relationship with each other. If one of the variable increases, the other vairable increases.

Use the relationship between the angles in the figure to answer the question.

Which equation can be used to find the value of x?

x+49−28=180
​x−49−28=180
​x + 49 + 28 = 180​
​x + 28 = 180​

Three lines making six angles with the top left angle at twenty eight degrees, the top right angled at forty nine degrees and the bottom middle angle at x degrees

Answers

Answer:

​x + 49 + 28 = 180​

Step-by-step explanation:

​The angles on a straight line with x° are 28° and 49° respectively, side by side with x°. This is because, vertical angles are equal. Therefore, the angle vertically opposite 28° and 49° are equal to 28° and 49° respectively.

Therefore, since angles on a straight line is 180°, thus:

​x + 49 + 28 = 180​

Answer:

​x + 49 + 28 = 180​

1 over 3 , 3 over 4 ,4 over 7 , 7 over 11, 11over 8 .... (i)one termof this sequence is p over q . Find the term of p and q , the next term in this sequence . Find the 6th term of this sequence 1).... 2).....

Answers

Answer:

Next term will be the 6th term i.e. a₆ will be:

a₆ = 14/11

Here:

p = numerator = 14q = denominator = 11

Step-by-step explanation:

Given the sequence

[tex]\frac{1}{3},\:\frac{3}{4},\:\frac{4}{7},\:\frac{7}{11},\:\frac{11}{8},...[/tex]

First of all the terms of the sequence are in p/q form, where p is the numerator and q is the denominator.

As the fifth term of the sequence is:

a₅ = 11/8

From the given sequence it is clear that the numerator is changing by 3 units and the denominator is also changing by 3 units.

Thus,

The next term will be the 6th term i.e. a₆ will be:

a₆ = 14/11

Here:

p = numerator = 14q = denominator = 11
