Answer:

Tanner's score = 70

Step-by-step explanation:

Data provided in the question:

Mean value of the statistics test taken by Tanner = 80

Standard deviation = 5

Total points possible = 100

Now,

It is given that the Tanner's score was 2 standard deviation below the mean

Mathematically,

Tanner's score = Mean - ( 2 × Standard deviation )

or

Tanner's score = 80 - ( 2 × 5 )

or

Tanner's score = 80 - 10

or

Tanner's score = 70

Please help me I need to get this done!!!
alukav5142 [94]

Answer:

y=-3x+4

Step-by-step explanation:

The question is asking for the equation in slope-intercept form. This is y=mx+b where m is the slope and b is the y-intercept.

The slope can be found by counting the units in between two points on the graph. Remember that slope is rise over run or y/x. Two points on the graph are (2,-2) and (1,1). The y is increasing by 3 while x is decreasing by 1. This means the slope is -3.

The y-intercept is where the line intersects with the y-axis. In this case, that point is (0,4). Therefore, b=4.

The final answer is y=-3x+4.

What is the standard form formula
vazorg [7]

Answer: The standard form of an equation is Ax + By = C. In this kind of equation, x and y are variables and A, B, and C are integers.

Explanation:

We can convert a point slope equation into standard form by moving the variables to the left side of the equation.

If f(x)=3^2 and g(x)=4x^3+1 , what is the degree of (f*g)(x)?
N76 [4]
I'm assuming you meant to say f(x) = 3x^2. If that assumption is correct, then the degree is found by multiplying the leading terms from both f(x) and g(x). The leading terms are 3x^2 and 4x^3

3x^2*4x^3 = (3*4)*(x^2*x^3) = 12x^(2+3) = 12x^5

The exponent of that result is 5, so the degree of (f*g)(x) is 5

Answer: 5
