A kindergarten teacher asked the students’ parents to send their child to school with two fruits (apples and/or oranges). Below

hichkok12 [17]

Answer:

The frequency of oranges is the classroom is 47.37%.

Step-by-step explanation:

The relative frequency of oranges is the number of oranges divided by the total number of fruits.

We have that:

8 students brought 2 apples each. So there are 8*2 = 16 apples

4 students brought an apple and an orange each. So there are 16 + 4*1 = 20 apples and 4*1 = 4 oranges.

7 students brough 2 oranges each. So there are 4 + 2*7 = 18 oranges.

There are 18 oranges, and 20+18 = 38 fruits in total.

So the frequency of oranges in the classrom is

$F = \frac{18}{38} = 0.4737$

The label on the car's antifreeze container claims to protect the car between −30°C and 130°C. To covert Celsius temperature to

jonny [76]

Answer:

-22°F < x < 266°F.

Step-by-step explanation:

The question states the incorrect formula to convert the Celsius temperature (C) into the Fahrenheit temperature (F). The correct one is given by:

F = 9C/5 + 32.

The given temperature inequality in Celsius is:

-30°C < x < 130°C; where x is any number that satisfies the inequality.

To convert it into Fahrenheit, simply plug in the values in the above formula.

Lower Limit:

F = 9(-30)/5 + 32.

F = -54 + 32.

F = -22°F.

Upper Limit:

F = 9(130)/5 + 32.

F = 234 + 32.

F = 266°F.

Therefore, the inequality will be -22°F < x < 266°F!!!
