What is the coefficient of the term 13a, in the expression 13a+ 6b, a, plus, 6b?
tamaranim1 [39]

The coefficient of the term 13a is 13

The coefficient of 6b in expression is a + 6b is 6

<em><u>Solution:</u></em>

<em><u>Given expression is:</u></em>

13a + 6b

We have to find the coefficient of 13a

The coefficients are the numbers that multiply the variables or letters

Here in 13a , a is the variable that is multiplied with number 13

Thus the coefficient of the term 13a is 13

<em><u>Second expression:</u></em>

a + 6b

Here, in 6b , b is the variable that is multiplied with number 6

so 6 is the coefficient

Plz Help!!! I need this Asap. Plz give an explanation and no guessing only answer if you know.
borishaifa [10]

Answer:

<h2>50°</h2>

Step-by-step explanation:

AB = AC

So, it is a isosceles triangle.

<B = <C = 65°

Sum of angles of triangle = 180°

< A + < B + <C = 180°

plug the values:

X + 65° + 65° = 180°

Calculate the sum

X + 130° = 180°

Move constant to R.H.S and change its sign

x = 180° - 130°

Calculate the difference

X = 50°

Hope this helps...

Good luck on your assignment...

20000 students took a standardized math test. The scores on the test are normally distributed, with a mean score of 85 and a sta
Tpy6a [65]

Answer: 2718

Step-by-step explanation:

Given: Mean score = 85

Standard deviation = 5

Let x be the score of a random student that follows normal distribution.

Then, the probability that a student scored between 90 and 95 will be

P(90< x < 95)\\\\=P(\dfrac{90-85}{5}

The number of students scored between 90 and 95 = 0.1359 x (Total students)

= 0.1359 (20000)

= 2718

Hence, The number of students scored between 90 and 95 = 2718
