You can only add/subtract like terms so:

2a+ab+2b+4a^2-3ab+9

2a-2ab+2b+4a^2+9  (the only like terms were ab and -3ab)

Use the intercept method to graph the equation y=-3
Strike441 [17]
What if I write the equation like this:
y = zero x - 3.
Now you know that the slope of the line is zero and its y-intercept is -3.
That's a horizontal line that crosses the y-axis at -3. And just like the equation says, the value of 'y' doesn't depend on 'x'. It's -3 everywhere.

valentinak56 [21]

Answer:

0.01  is alpha level

Step-by-step explanation:

Given that a survey of a magazine of 1500 adults revealed that 12% chose chocolate pie.

i.e. p = proportion of people who like chocolate pie = 0.12

Margin of error = ±0.03

The value of   q  =1-\hat p , =1-0.12 = 0.88


The sample size n  is given as 1500. Therefore,  n=1500

The confidence level is given as 99%

Hence alpha = 1- confidence level


=1-0.99=0.01

Hence answer is 0.01

A manufacturer of skis offered chain discounts of 10/5/4 to many of its customers. Joe Jones ordered skis that had a total list
kati45 [8]
First, 
149,500 * .10 = 14,950
149,500 - 14,950 = 134,550

then,
134,550 * .05 = 6727.50
134,550 - 6727 = 127,822.55 
127,822.50 * .04 = 5112.90

trade discount = 14950 + 6727.50 + 5112.90 
26790.40

In Class 1, what is the median score? A) 70 B) 70.5 C) 71.5 D) 72
evablogger [386]

Answer:

B)  70.5

Step-by-step explanation:

Median = middle value when the values are placed in order.

If there are two middle values, the median is the mean of those two values.

<u>Class 1</u>

45 46 51 52 53 53 61 63 64 65 66 68 70 <u>70 71</u> 73 76 77 79 81 82 83 84 87 90 92 93 95

There are 28 values in Class 1.

Therefore, there are two middle values: 14th and 15th values

14th value = 70

15th value = 71

\implies \textsf{Median}=\dfrac{70+71}{2}=70.5
