Slope-intercept form is y=mx+b
we know m is 10 and we have x and y
if you plug in x, y and m and solve for b, like this
y=mx+b
1=10 (7) + b
1=70+b
-69=b
so now we know b is -69. just plug that in
the final answer is y=10x-69

25 = -16t^2 + 50t + 4
16t^2 - 50t + 21 = 0
16t^2 - 8t - 42t + 21 = 0
8t(2t - 1) - 21(2t - 1) = 0
(8t - 21)(2t - 1) = 0
8t - 21 = 0 or 2t - 1 = 0
t = 21/8 or t = 1/2
t = 2.625 or t = 0.5

NeverReady batteries has engineered a newer, longer-lasting AAA battery. The company claims this battery has an average life spa
melomori [17]

Answer:

the probability is 0.0202

Step-by-step explanation:

The computation is shown below:

Given that

The Average life span = 17 hours

Standard deviation = 0.8 hours

Sample = 30 batteries

Sample mean = 16.7 hours

Now based on the above information

The probability is

P (\bar x \leq 16.7) = P (\frac{\bar x - \mu}{(\frac{\sigma }{\sqrt{n} } )} \leq  (\frac{16.7 - \mu}{(\frac{\sigma }{\sqrt{n} } )}\\\\= P(z\leq \frac{16.7-17}{\frac{0.8}{\sqrt{30} } } )\\\\= P(\leq -2.05)\\\\= 0.0202

Hence, the probability is 0.0202

About 250,000 people of a certain community live in the country. Of that number, 73,920 live in state A and state B. The number
Elodia [21]

Answer:

15 360 people in State A and 58 560 in State B

Step-by-step explanation:

We have two conditions:

(1) A + B = 73 920

(2)      B = 3A + 12 480

Solve the system of equations. Substitute (2) into (1).

A + 3A + 12 480 = 73 920     Subtract 12 480 from each side

                     4A = 61 440

(3)                   A = 15 360      Substitute (3) into (2)

                       B = 3×15 360 + 12 480

                          =   46 080    + 12 480

                          = 58 560

There are 15 360 people in State A and 58 560 in State B.

<em>Check: </em>

(1) 15 360 + 58 560 = 73 920     (2) 58 560 = 3×15 360 + 12 480

                   73 920 = 73 920          58 560 =    46 080  + 12 480

                                                         58 560 =    58 560
