By what percent did the Howard family's woter bill increase from April to May? april $60.00 may $65.00

Ainat [17]

Answer:

8 percent

Step-by-step explanation:

You have to put the biggest number first, then subtract 65.00 and 60.00. You would get 5, then divide 5 and the original number (60.00). You would get 0.0833333333. Move the decimal two spots to the right. You would get 8 percent. Hope this helps!

4.14 Defective rate. A machine that produces a special type of transistor (a component of computers) has a 2% defective rate. Th

scZoUnD [109]

Answer:

Step-by-step explanation:

Given that transitor has a 2% defective rate, need to calculate the probability that the 10th transistor produced is the first with a defect.

The probability function is p(x=k) = (1-p)^(n-1) * p

p = (1-defective rate)^(n-1) * defective rate; n=10

p = (1-0.02)^9 * 0.02 = 0.98^9 * 0.02 = 0.01666

Olivia kicks a soccer ball from the ground with an initial vertical velocity of 15 m/s. Which equation can be used to find the t

babunello [35]

Answer:

The answer is below

Step-by-step explanation:

Motion shows the change in the position of an object over time. This change is showed in terms of displacement, distance, velocity, acceleration, time and speed. The equations of motion shows this relationship.

Since the soccer ball is kicked up with an initial velocity (u) of 15 m/s, the acceleration due to gravity (g) acts on the ball. If the ball is kicked at an angle Θ, the time t it takes for the ball to reach the ground is:

$t=\frac{2u*sin(\theta)}{g} \\\\t=\frac{2(15)*sin(\theta)}{g} \\\\t=\frac{30*sin(\theta)}{g} \\\\If\ it\ is\ kicked\ vertical\ then\ \theta=90^0,hence:\\\\t=\frac{30*sin(90)}{g}= \frac{30}{g }$

Last week Macy ran 4 times as many miles as Jackson. They ran a total of 20 miles. How many miles did Macy run? how many morr mi

WITCHER [35]

Macy 5 miles because she ran 4 times more than Jackson in relation to Jackson ran 5 mile, this problem can oftenly be seen as
$j = 20 \div 4$
which would end up in the answer being 5 which is the right answer while someone else can see it as
$j = 20 - 4$
which would equal 16 which is incorrect because the problem didn't say that Jackson ran one mile nor 4 miles which would be 4*4 or 16 when the correct answer is 20/4=5 because 4*5=20
