Answer:

Option B,They are not valid because the student did not control all the variables that can affect plant growth

Step-by-step explanation:

In case of water applied to the plants - the student watered the plant to which he has spoken by hand and to the remaining plants to which he has not spoken, he watered them by using sprinkler.

Water is an essential factor that effects plant growth. This factor must have been controlled. However, the water was given to both the plants only the quantity of water given varies in the two cases. Hence, the claim of student is not valid.

Hence, option B is correct

(Q5) Decide if the function is an exponential function. If it is, state the initial value and the base. y=3.1^x

ycow [4]

Answer:

Step-by-step explanation:

Exponential equation takes the form $y=ab^x$ where

a is the initial value ( a ≠ 0), and

b is the base ( b ≠ 1)

The equation given can be written as $y=3.1^x\\y=1*3.1^x$ . Thus, it is an exponential equation.

So a = 1 and b = 3.1

Thus we can say that the initial value = 1 and the base is 3.3

A restaurant sees about 600 orders on Tuesday. This is down from last Tuesday by about 0.85%. How many did they see last Tuesday

zaharov [31]

Answer:

Number of orders seen on last Tuesday = 605

Step-by-step explanation:

Number of orders seen on Tuesday = 600

It is given that it is 0.85% less than last Tuesday.

Let number of sales on last Tuesday = $x$

As per question statement:

Number of order on last Tuesday - 0.85% of Number of order on last Tuesday = 600

i.e. if we subtract 0.85% of x from x, it must be equal to 600.

$x-\dfrac{0.85}{100}x =600\\\Rightarrow x-\dfrac{0.85}{100}x =600\\\Rightarrow \dfrac{100-0.85}{100}x =600\\\Rightarrow \dfrac{99.15}{100} \times x =600\\\Rightarrow x =\dfrac{600\times 100}{99.15}\\\Rightarrow x =\dfrac{60000}{99.15}\\\Rightarrow x \approx 605$

So, there were about 605 order seen last Tuesday.
