Answer:
Step-by-step explanation:
t1 means a1 and t7 means a7
a+(n-1)d=an
a+(1-1)d=4
so we get a as 4
<u><em>a=4</em></u>
a+(n-1)d=an
4+(7-1)d=22
4+6d=22
6d=22-4
d=18/6
<u><em>d=3</em></u>
A line of symmetry<span> for a graph. The two sides of a graph on either side of the </span>axis of symmetry<span> look like mirror images of each other. Example: This is a graph of the parabola y = x</span>2<span> – 4x + 2 together with its </span>axis of symmetry<span> x = 2. The</span>axis of symmetry<span> is the red vertical line.

Answer: The number of air conditioners sold per day in a city and the daily temperature
Step-by-step explanation:
We know that if there is a causal relationship between two variables then one variable is responsible for causing the other variable.
- the number of hats sold and the number of mittens sold in a city.
there is no causal relationship between the variables since both are independent variables.
- the amount of butter and the amount of bread consumed by a family
.
there is no causal relationship between the variables since both are independent variables.
- the number of notebooks sold and the number of pens sold in a stationery store
.
there is no causal relationship between the variables since both are independent variables.
- the number of air conditioners sold per day in a city and the daily temperature
.
there can be causal relationship between the variables since by increasing or decreasing temperature the the number of air conditioners sold per day in a city can be increased or decreased respectively.
- the number of hours a person can swim and the depth of the pool.
there is no causal relationship between the variables since both are independent variables.

. Correct option is A)
<u>Step-by-step explanation:</u>
Here we have , Peter has just purchased a small rectangular fish tank that holds 910 milliliters of water. The tank has a width of 7 cm and a height of 10 cm. We need to find What is the length of the fish tank . Let's find out:
The fish tank is in the shape of cuboid , and we know that volume of cuboid :
⇒ 
Now , according to question we have following parameters :
Therefore , Putting theses values in above equation we get :
⇒
⇒ 
⇒ 
⇒
Therefore , the length of the fish tank is . Correct option is A)
