The ratios that have a unit rate of 5 will be:

6 1/4 kilometers to 1 1/4 minutes.

1 kilometer to 1/5 minutes

1/3 kilometers to 1 2/3 minutes

<h3>How to calculate the value?</h3>

The ratios will be:

1. 6 1/4 to 1 1/4

= 6.25 : 1.25

= 5

2. 4 1/2 to 2

= 4 1/2 / 2

= 2.25

3. 4/5 to 5 minutes

4. 1 kilometer to 1/5 minutes

= 1 : 1/5

= 1 / 0.2

= 5

5. 3 1/10 : 3/10

= 10

6. 1/3 : 1 2/3

= 5

Therefore, the correct options are 1, 4 and 6.

Answer:

c)"At least 1 O+" is equivalent to "not none O+" (forgive the incorrect English).

P(not none O+)+P(none O+)=1

P(not none O+)=1-P(none O+)

P(not none O+)=1-0.00491

P(at least 1 O+)=0.995

Amelia need 1/2 stick of butter to make cornbread he also needs one fourths stick butter to make apple muffins what fraction of

Viktor [21]

Amelia needs $\frac{3}{4}$ stick of butter to make cornbread and apple muffins.

Step-by-step explanation:

Given,

Stick of butter needed to make cornbread = $\frac{1}{2}$

Stick of butter needed to make apple muffins = $\frac{1}{4}$

Total stick of butter needed = Cornbread + Muffins

Total stick of butter needed = $\frac{1}{2}+\frac{1}{4}$

Total stick of butter needed = $\frac{2+1}{4}$

Total stick of butter needed = $\frac{3}{4}$

Amelia needs $\frac{3}{4}$ stick of butter to make cornbread and apple muffins.

The vertex of this parabola is at (3,5). When the Y value is 6X value is negative one what is the coefficient of the squared ter

iren2701 [21]

We know that equation of a parabola is given by :-

y = a(x-h)² + k

Where (h,k) is the vertex of parabola and (x,y) is any point on its curve.

Given that vertex of parabola is (3,5) and one point (x,y) is (6,-1).

We can plug the given information in the equation of parabola and solve it for value of 'a' :-

-1 = a(6 - 3)² + 5

-1 = a(3)² + 5

-1 = 9a + 5

9a = -1 -5 = -6

a = $\frac{-6}{9} = \frac{-2}{3}$

a = $\frac{-2}{3}$ is the final answer.
