A cell phone company is trying to find a waterproof cell phone case to add to its product line. Company managers know that plast

ic and silicone will be used. They also know that the depth of the water—less than five feet, between five feet and 20 feet, and more than 20 feet—affects the waterproof case. An experiment will compare all combinations of these choices. The cell phones will be subjected to each treatment, with one group dropped in water without a case, and all phones will be scored for quality. What is the control?
a. Cell phones in the plastic case
b. Cell phones in the silicone case
c. Cell phones in the plastic case dropped in water less than five feet deep
d. Cell phones in the silicone case dropped in water more than 20 feet deep
e. Cell phones with no case

Answer: the cell phones with no case

Step-by-step explanation:

this is because this is the option that neither the subject nor the group is tested for the dependent variable which is what helps you find a conclusion.

WRITE 0,000003 56 IN SCIENTIFIC NOTATION ​
Elanso [62]

Answer:

3.56X10^-6

Step-by-step explanation:

In converting numbers to scientific notation, simply move the decimal point of the number until the numerical coefficient is greater than 1 but less than 10. Be sure to take note of the following:

1. The numerical coefficient.

2. Number of times we move the decimal point. It will be the exponent with the base of 10.

3. The direction we take in moving the decimal point. If the direction is to the right, take the negative sign for the exponent. If the direction is to the left, take the positive sign for the exponent.

Here, we move the decimal point of 0.00000356 to the right 6 times. So, we have now 3.56X10^-6.

Hello there ^ _ ^


We know that 36 plates filled 1 box
if we have 1000 plates, how many box it would fill.

All we have to do is divide 1000 by 36 to find the answer.

1000/ 36 = 27.77777 or you can just say 28

Graph the function f(x)=4x^2+ 3x - 1
Marizza181 [45]

Step-by-step explanation:

The graph of a quadratic function is a U-shaped curve called a parabola. One important feature of the graph is that it has an extreme point, called the vertex. If the parabola opens up, the vertex represents the lowest point on the graph, or the minimum value of the quadratic function. If the parabola opens down, the vertex represents the highest point on the graph, or the maximum value. In either case, the vertex is a turning point on the graph. The graph is also symmetric with a vertical line drawn through the vertex, called the axis of symmetry.

Graph of a parabola showing where the x and y intercepts, vertex, and axis of symmetry are.

The

y

-intercept is the point at which the parabola crosses the

y

-axis. The

x

-intercepts are the points at which the parabola crosses the

x

-axis. If they exist, the

x

-intercepts represent the zeros, or roots, of the quadratic function, the values of

x

at which

y

=

0

.

Write an equation for the line that contains the points (-5,50) and (-15,0).
gtnhenbr [62]

Answer:

y=5

Step-by-step explanation:

The equation of a line can be written as y − y 0 = m ⋅ ( x − x 0 ) where ( x 0 , y 0 ) is any point that lies on the line. The gradient, m , of the line can be found using any two non-identical points that lie on the line. m = y 2 − y 1 x 2 − x 1 = 5 − 5 − 3 − 0 = 0 A gradient of zero indicates that the line is horizontal. The equation of the line can thus be simplified to y = y 0 In this case, both points have a y coordinate of 5. The equation of this line is therefore y = 5 .
