Describe a real-life situation where the probability of an event is 1. Then describe the complement of that situation.

It is more likely that the Grade 7 pupils will be in the science club because 70 is more than 55.

It is defined as the frequency that can be evaluated by the two-way frequency table. Usually, we can obtain this frequency by dividing the frequency that is not in the total frequency cell by the total frequency.

As we can see in the table:

Grade 7 = 10/11

Grade 8 = 5/7

Or after making the common denominator:

Grade 7 = 70/77

Grade 8 = 55/77

Thus, it is more likely that the Grade 7 pupils will be in the science club because 70 is more than 55.

Answer:

21

Step-by-step explanation:

Volume of Rectangular Prism: LWH: Length * Width * Height

Volume of Rectangular Prism: [tex](1\frac{1}{2}) *(4)*(3\frac{1}{2})[/tex]

=> You can convert mixed fractions into improper fractions by the following steps so it's easier to solve the equation:

=> [tex]1\frac{1}{2}[/tex] would be [tex]\frac{3}{2}[/tex] as an improper fraction; [tex]3\frac{1}{2}[/tex] would be [tex]\frac{7}{2}[/tex] as an improper fraction. Whereas 4 would remain the same since it's a whole number.

=> Now, multiple everything together:  ([tex]\frac{3}{2}[/tex]) * (4) * ([tex]\frac{7}{2}[/tex])

The answer would be 21!

h = 12 cm

Step-by-step explanation:

3053.63=πr^2h

Let r=9 and approximate pi as 3.14

3053.63=3.14 ( 9)^2 h

3053.63=3.14*81*h

3053.63=254.34h

Divide each side by254.34

3053.63/254.34=254.34h/254.34

12=h

Answer:

9sqrd= 81

12sprd= 144

144+81= 225

[tex]\sqrt{225}[/tex]= 15

so c=15

ps. use Pythagoras to help you.  

Answer:

[tex]c=15[/tex]

Step-by-step explanation:

You can use Pythagoras theorem to find the value of c

Formula to find the hypotenuse:

[tex]c=\sqrt{a^{2}+b^{2} }[/tex]

The value of a in the formula will be the height & the value for b in the formula is the base.

Now, add the values in the formula:

[tex]c=\sqrt{9^{2}+12^{2} }[/tex]

[tex]c=\sqrt{81+144 }[/tex]

[tex]c=\sqrt{225}[/tex]

[tex]c=15.96871942[/tex]

You can simply say that:

[tex]c=15[/tex]

Answer:

A

Step-by-step explanation:

Answer:

quartile 1 is 39

quartile 2 is 69.5

quartile 3 is 78

the minimum is 37

the maximum is 82

IQR is 39

Step-by-step explanation:

you organize the data so that it’s from least to greatest. quartile 2 would be 69.5 because 67 and 72 were both in the middle. When that happens, you add them both and divide by 2. For the other quartiles you find the middle number of both sections :)

the IQR is just (quartile 3 - quartile 1)

what do you mean by 2 1 2 pounds less?

The cat’s target weight, in pounds and ounces is,

⇒  8.75 pounds

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

Given that;

A cat weighs 11 pounds 4 ounces.

And, The cat’s target weight is 2 1/2 pounds less than its current weight.

Now,

1 pound = 16 ounces

1 ounces = 1/16 pounds

Hence, A cat weighs 11 pounds 4 ounces in pounds is,

⇒ 11 pounds + 4/16 pounds

⇒ 11 + 1/4

⇒ 45 / 4 pounds

Hence, The cat’s target weight, in pounds and ounces is,

⇒ 45 / 4 - 2 1/2

⇒ 45/4 - 5/2

⇒ 45 / 4 - 10 / 4

⇒ 35 / 4 pounds

⇒ 35 / 4 x 16

⇒ 140 ounces

⇒ 8.75 pounds

The the triangles are scaled copies of triangle A are C and E.

A scale factor is defined as the ratio between the scale of a given original object and a new object, which is its representation but of a different size (bigger or smaller).

The basic formula to find the scale factor of a figure is expressed as,

Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape.

From triangle A to C scale factor is 2 units

From triangle A to E scale factor is 4 units

The the triangles are scaled copies of triangle A are C and E.

Answer:

1. 6 2. -5

Step-by-step explanation:

On negatives you add.

Answer:

6 for the first one, then -5 for the next one

Step-by-step explanation:

alright, first one.

starts from 0 on a number line and hops 4 right, add 4. [ positive is right, negative is left ]

0 + 4 = 4

coming from 4, to 6 on the left, so either add -6 or subtract 6, both work either way.

4 + (-6) = -2

finally, we land up on -2, and then 8 units to the right once again, which would be adding 8.

-2 + 8 = 6

so that would be 6.

second one, inverse means opposite. so they're asking for the opposite of positive 5, which is negative 5. (-5)
