Null hypothesis is stated as H0: Sunflower seeds planted in well-drained soil will grow faster than sunflower seeds planted in wet soil.

Null hypothesis is defined as the hypothesis that stated that there is no relationship between the two population parameters. It is denoted by H0

To form the null hypothesis we take it as

   Null hypothesis : The sample data provides no evidence to support some claim being made by an individual.

Thus according to the question the null hypothesis can be stated as

 Null hypothesis, h0 : Sunflower seeds planted in well-drained soil will grow faster than sunflower seeds planted in wet soil.

Use the quadratic formula to find the solutions to the quadratic equation below x^2-7x-3=0
cupoosta [38]

the roots are \frac{7+\sqrt{61} }{2} and \frac{7-\sqrt{61} }{2}

Step-by-step explanation:

here we use Shridhar acharya formula

if ax^{2} + bx +c = 0 is the quadratic equation

the the roots are , \frac{-b +\sqrt{b^{2-4ac} } }{2a} and \frac{-b -\sqrt{b^{2-4ac} } }{2a}

comparing with the equation we get a=1 b= -7 c = -3

hence the roots are \frac{7 +\sqrt{7^{2-4X1X(-3)} } }{2X1} and \frac{7 -\sqrt{7^{2-4X1X(-3)} } }{2X1}

= \frac{7+\sqrt{61} }{2} and \frac{7-\sqrt{61} }{2}

The figure shown in the right is made up of a square and a circle. Find the perimeter of the shaded region.
Tasya [4]

Answer:

B. 12 + 2pi cm

Step-by-step explanation:

The shaded region is made up of 3 square sides and one half circle. The three square sides are each 4, which means that those altogether equal 12.

The circle's circumference can be found by using the equation c = (d)pi

The diameter is 4, so the whole circumference is 4pi. However, you only need half of a circle, which is represented by 2pi.

Add them all together, and you get 12 + 2pi cm.

Step-by-step explanation:

The fishbowl is shaped like a sphere the fishbowl has a diameter of 16.

What is the closest value of water in the Fishbowl in cubic inches?

From the any question, we were told to find the closest value of the water in the fishbowl in cubic inches.

This means we are to find the volume.

The volume of a sphere is given as:

4/3πr³

We are given Diameter of the fish bowl = 16 inches

Radius = Diameter/2 = 16 inches/2

= 8 inches

Hence,

Volume of the sphere (Volume of water) = 4/3 × π × 8³

= 2144.66 cubic inches
