Answer:
y=2x-3
Step-by-step explanation:
y=mx+c
m=gradient=
5-(-5)/4-(-1)
=10/5
=2
c=y intercept=-3
y=2x-3

Answer:
D. If a sum of two numbers is multiplied by a factor, you can multiply each number by that factor and then add the products.
Step-by-step explanation:
The point of the distributive property is that it allows multiplication to be distributed over addition. That is, ...
a(b +c) = ab +ac
The product of a factor and a sum is the same as the sum of the products of that factor with each of the elements of the sum. This is expressed in statement D.
__
Statement A refers to the commutative property of multiplication.
Statement B is a restatement of the multiplication rule in the "order of operations."
Statement C refers to the associative property of multiplication.
Statement D is a restatement of the distributive property.
Answer:
If the task is performed in less than or equal to 130.8 seconds, then, the individuals qualify for advanced training.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 150 sec
Standard Deviation, σ = 15 sec
We are given that the distribution of time taken is a bell shaped distribution that is a normal distribution.
Formula:
We have to find the value of x such that the probability is 0.10
P(X < x)
Calculation the value from standard normal z table, we have,
Thus, if the task is performed in less than or equal to 130.8 seconds, then, the individuals qualify for advanced training.
Answer:
x = 2.4
y = 31
Step-by-step explanation:
Angle B = 25x
BC = 31
therefore , this is an equilateral triangle all sides and angles are equal,
25x =60
x = 2.4
BC = BA = AC
y= 31
We calculate this by multiplying the number of cookies by the number of boxes:
28*14=(20+8)*14=280+80+32=360+32=392 (that's how I like to count it, there are also other methods)
so she has 392 cookies in common.
