A sales manager collected data on annual sales for new customer accounts and the number of years of experience for a sample of 1
Pavlova-9 [17]

Answer:

(1)-

b1 =~3.4

bo= ~ 82.8

(2)- ý=[82.8]+[3.4] x

(3)- The change in annual sales ($1000) for every year of experience is= 3.4

(4)-r^2=~ 0.847

Estimated annual sales= $110514

Step-by-step explanation:

(1)- b1 = 3.4606

=~3.4

bo = 82.8296

= ~ 82.8

(2)-

ý=[82.8]+[3.4] x

(3)-The change in annual sales ($1000) for every year of experience is= 3.4

(4)- r^2 = 0.84776

=~ 0.847

Percentage of the variation in annual sales can be explained by the years of experience

of the salesperson 84.7%.

Estimated annual sales

= 82.8296 + 3.4606 × 8 ($ 1000).

= 110.5144 ( $1000)

= $ 110514:4

= $110514

Greenwood Lake is pictured below on a grid where each square has sides that are 1 mile long.
alisha [4.7K]
6 square units.
1 sq units would be 1 mile, so 4 units are 4 miles. A little bit more than 4 is 6.

The speed limit on a highway is 70 miles per hour about how fast is this in miles per minute
Kruka [31]
\frac { 70 \textrm{ miles}}{1 \textrm{ hour}} = \frac {70 \textrm{ miles}}{60 \textrm{ minutes}} = \frac{70}{60} \frac{\textrm{ miles}}{ \textrm{ minute}} = 1.167 \textrm{ mile per minute }

#16 and #19 only <br> Please answer both as soon as possible.

Answer:

1. it is not a direct variation because the value <em>k</em> is not kept throughout the ordered pairs

2. -a^5 - 2a³ + 2a², leading coefficient is -1

Step-by-step explanation:

1. to find the direct variation, we will use y/x = k with k representing our constant throughout the chart. if every value is equal to k, it is a direct variation

for this problem we will assume that the cup sizes are x and the cost is y

so the ordered pairs are (8, 0.90), (12, 1.35), (16, 1.80), and (24, 2.25)

.90/8 = 0.1125 <-- this is our <em>k</em> value for which every result has to be equal to

1.35/12 = 0.1125

1.80/12 = 0.1125

2.25/24 = 0.09375

since the value <em>k</em> was not kept throughout the ordered pairs, this is not a direct variation

2. the standard form of a polynomial is the exponents in descending order.

we have the following polynomial: 2a² - a^5 -2a³

to write it in standard form, we will go in descending order of the exponents. the largest exponent being first

-a^5 - 2a³ + 2a²

the leading coefficient of the polynomial is -1, as there is a negative sign in front of the newly formed polynomial
