Is this a matched pairs design for this experiment? Yes, the company used 24 different vehicles
Yes, both types of tread were randomly assigned to
each vehicle.
No, the vehicles were not put into groups of two
No, the tires with the different types of tread were
not randomly assigned to each vehície,
A tire company wants to determine if tires made with a
new type of tread will last longer than tires made with
the original type of tread. The company has access to
24 different vehicles. Each vehicle will receive four tires
with the new tread and four with the original tread. The
position, front or back, will be randomly determined for
a pair of each type of tread. For example, a vehicle will
have the new type of tread on the front tires and the
original tread on the back tires. After six months, the
pairs of unused tires will be used with the position
switched on the car. The vehicles will be driven for six
more months. At the end of one year, the depths of the
remaining tread will be measured for each fire and the
average differences between the new and original
tread types will be determined. The average
differences will then be used to determine if the new
tread does last longer.

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3

you are playing an adventure game on your computer. you come across a troll who won't let you pass and there is no other way to get to the other side of the river except over the bridge he is guarding.

the troll is a nerd. he takes great delight in watching people struggle with his problems. very few get them. he only gives you one chance and then he changes the puzzle. you have to solve this one.

before you are four blocks. they are numbered 11,6, -7,21.

he tells that the answer he wants is minus and between -1 and - 2. you can use +, -, ×, ÷   ( and ) as many times as you like or no times at all. you don't like the way he's looking at you, but you need to cross the bridge. what do you do?

the answer to this in exact form is 4/35 but in decimal form its 0.1142857

hope this if needed hmu

answer: certain

step-by-step explanation:

the probability of any event is a number which tells the chances that the event will happen or not .

an event that is certain to happen has a probability of 1.

an event that is uncertain to happen has a probability of 0.

therefore, if the the probability of choosing an apple-flavored juice box out of the refrigerator without looking is 1 .
