Answer:

a) F

b) B, E, D

Step-by-step explanation:

a) The segment with the greatest gradient has the largest change in y-values per unit change in x-values

From the given option, the rate of change of the <em>y </em>to the<em> </em>x-values of B = the gradient = (4 units)/(2 units) = 2

The gradient of F = (-3units)/(1 unit) = -3

The gradient of A = 4/4 = 1

The gradient of C = -2/5

The gradient of D = 2/6 = 1/3

The gradient of E = 3/4

The segment with the greatest gradient is F

b) The steepest segment has the higher gradient

From their calculated we have;

The gradient of segment B = 2 therefore, B is steeper than E that has a gradient of 3/4, and E is steeper than D, as the gradient of D = 1/3

Therefore, we have;

B, E, D.

Ally's science class was looking at bacteria through a microscope. Ally's teacher said some bacteria can be as small as 0.00365

mamaluj [8]

The length of the bacteria should be written in scientific notation.

0.00365 in scientific notation = 3 × 10^-3

Given.

length of the bacteria in decimal = 0.00365 cm long

Scientific notation is written in the format x × 10ⁿ

where,

x = any number between digit 1 and 10

n = exponent (positive or negative).

To have a negative exponent value, move decimal to the right

To have a positive exponent value, move the decimal point to the left.

In this case, the nearest significant value is 3

So move the decimal point three times to where 3 is

That is,

0.00365 = 3.65

Since the decimal point is moved to the right 3 times, n = - 3

we have 10^-3

Therefore,

0.00365 in scientific notation = 3 × 10^-3

Answer: x = 56

It’s a supplementary angle

Step-by-step explanation:

It’s a supplementary angle if their measures add to 180 degrees

is the equation

2x + 68 = 180 degrees

2x = 180 -68

2x = 112

x = 112/2

x = 56

Find the probability.

andrew11 [14]

Answer:

The Probability of getting lemon drink on both draws is 1/16

The Probability of getting diamond on both cards is 1/17

Step-by-step explanation:

No. of lemon-lime flavored bottle = 3

No. of orange flavored bottle = 4

No. of fruit punch flavored bottle = 5

Total bottles = 12

We are given that You randomly grab a bottle. Then you return the bottle to the cooler,mix up the bottles, and randomly select another bottle. Both times you get a lemon-lime drink.

Probability of getting lemon drink on both draws with replacement = $\frac{3}{12} \times \frac{3}{12} = \frac{1}{16}$

So, The Probability of getting lemon drink on both draws is 1/16

No. of diamond cards = 13

Total cards =52

Probability of getting diamond on first card = $\frac{13}{52}$

Probability of getting diamond on second card = $\frac{12}{51}$

Probability of getting diamond on both cards = $\frac{13}{52} \times \frac{12}{51}=\frac{1}{17}$

So, The Probability of getting diamond on both cards is 1/17
