To calculate percent change:
(difference between original and new)/original * 100
(19-15)/15 * 100 =
4/15 * 100 = 26.7 % increase

Answer:

The answer to your question is below

Step-by-step explanation:

1.- (2b - 1) (b + 8) = 0

    2b - 1 = 0           b + 8 = 0

     b = 1/2              b = -8

2.- (x + 3)(x - 12) = 0

     x + 3 = 0            x - 12 = 0

     x = -3                  x = 12

3.- (4b+ 7)(b + 11)

    4b + 7 = 0           b + 11 = 0

      b = -7/4             b = -11

4.- (k - 8)(k + 6)

     k - 8 = 0             k + 6 = 0

    k = 8                   k = -6

5.- (2n + 12)(5n+ 10)

     2n + 12 = 0             5n + 10 = 0

       n = -12/2 = -6          n = -10/5 = -2

6.- (w - 3)(3w - 7)

      w - 3 = 0                3w - 7 = 0

      w = 3                        w = 7/3

7.- (6n - 5)(n - 10)

     6n - 5 = 0                n - 10 = 0

      n = 5/6                   n = 10

8.- (n + 12)((4n + 7)

     n + 12 = 0                 4n + 7 = 0

     n = -12                         n = -7/4

9.- (3b + 4)(5b - 10)

      3b + 4 = 0                 5b - 10 = 0

       b = -4/3                     b = 10/5 = 2

10.- (p - 6)(p + 10)

       p - 6 = 0                  p + 10 = 0

       p = 6                        p = -10

George and Carmen went on a bicycle trip. they took a bus to their starting point, and then biked the rest. They traveled 3oo ki
jeka94

Answer:

George and Carmen traveled 185 kilometers by bike and 115 kilometers by bus

Step-by-step explanation:

<u><em>The question is</em></u>

Find how many kilometers they traveled by bike

Let

x ---->  kilometers traveled by bike

y ---->  kilometers traveled by bus

we know that

They traveled 300 kilometers in total

so

x+y=300 ----> equation A

They biked 70 kilometers more than they were bus

so

x=y+70 ----> equation B

substitute equation B in equation A

(y+70)+y=300

solve for y

2y+70=300\\2y=300-70\\2y=230\\y=115

<em>Find the value of x</em>

x=115+70=185

therefore

George and Carmen traveled 185 kilometers by bike and 115 kilometers by bus

A value of 0.2 for the z value after conducting a one-sample z test leads to which conclusion (critical value 1.96)?
Katyanochek1 [597]

Answer:

Accept the null hypothesis

Step-by-step explanation:

It leads to the conclusion to accept the null hypothesis.

The upper value corresponds to 1 – 0.025, or 0.975, which gives a z‐value of 1.96. The null hypothesis of no difference will be rejected if the computed z statistic falls outside the range of –1.96 to 1.96.
