Answer:
(I suppose that we want to find the probability of first randomly drawing a red checker and after that randomly drawing a black checker)
We know that we have:
12 red checkers
12 black checkers.
A total of 24 checkers.
All of them are in a bag, and all of them have the same probability of being drawn.
Then the probability of randomly drawing a red checkers is equal to the quotient between the number of red checkers (12) and the total number of checkers (24)
p = 12/24 = 1/2
And the probability of now drawing a black checkers is calculated in the same way, as the quotient between the number of black checkers (12) and the total number of checkers (23 this time, because we have already drawn one)
q = 12/23
The joint probability is equal to the product between the two individual probabilities:
P = p*q = (1/2)*(12/23) = 0.261

Answer:
360 ft²
³
Step-by-step explanation:
The volume of the rectangular pyramid is calculated as
V = [tex]\frac{1}{3}[/tex] Ah ( A is the area of the base and h the perpendicular height )
Here A = 10 × 6 = 60 ft² and h = 6 , then
V = [tex]\frac{1}{3}[/tex] × 60 × 6 = 20 × 6 = 120 ft³
The volume of the rectangular prism is calculated as
V = 10 × 6 × 4 = 60 × 4 = 240 ft³
Total volume = 120 + 240 = 360 ft³

Answer:
option c
Step-by-step explanation:
first use angle sum property, then use
linear pair axiom
Answer:
D: 121
Step-by-step explanation:
Step One: To do this problem, you must understand the rule that all angles in a triangle add up to 180 degrees.
Step Two: Now that we know the rule, we know this triangle equals 180 degrees. First, we must add the angles we DO know together: 26+33= 59.
Step Three: We can subtract 59 from 180 to find the missing angle: 180-59= 121.

I made a fort by connecting two boxes. The first box is 5 meters long, 9 meters wide, and 9 meters high. The second box is 3 meters long, 8 meters wide, and 2 meters high.
Complete question :
I made a fort by connecting two boxes. The first box is 5 meters long, 9 meters wide, and 9 meters high. The second box is 3 meters long, 8 meters wide, and 2 meters high. How many cubic meters of space does my fort have?
Answer:
453 m³
Step-by-step explanation:
Volume of first box :
Volume = Length * width * height
Volume = 5 * 9 * 9
Volume = 405 m³
Volume of second box :
Volume = Length * width * height
Volume = 3 * 8 * 2
Volume = 48 m³
Total volume :
405m³ + 48m³ = 453m³

The measures of two complementary angles are in the ratio of 2 : 7. Find the measurements of the two angles.
Answer: 20° & 70°
Step-by-step explanation:
We know complementary angles will add up to 90° and we also know we can divide the total by 9 parts because our ratio is 2 parts to every 7 parts.
To find each individual part size...
9x=90
x=10
so use our ratio...
2x10=20 for first angle
7x10=70 for second angle

Ms. Padilla orders 144 jars of paint.
O True
O False
The ratio of sketch pads to jars of paint in Ms. Padilla's order can be written as
25 : 12
O True
O False
The ratio of jars of paint to sketch pads in Ms. Padilla's order can be written as
4:5.
o
O True
O False
Answer:
1. False
Sketch pads ordered: 10(90/3) = 10×30 = 300
2. True
Painting jars ordered: 8(90/5) = 8×18 = 144
3. True
(25×12)/(12×12) = 300/144
or
25/12 = 300/144 = 2.083..
4. False
Since the previous statement isn't 5:4 and it's true, then this statement is false.

Which statement about the data is true?
A. The MAD for group A is more than the MAD for group B.
B. The mean number of lessons for group A is greater than the mean
for group B by 6 MADs.
C. The mean number of lessons for group A is greater than the mean
for group B by 2 MADs.
D. On average, the dogs in group B required more lessons than the
dogs in group A.
Answer:
C. The mean number of lessons for group A is greater than the mean for group B by 2 MADs.
Step-by-step explanation:
Mean of Group A is greater than the mean of group B. The mean absolute deviation for the group A and B is 3. The different between the mean is 6 (15 - 9)
Number of mean absolute deviations is :
Difference between mean of two groups / MAD

Zoe works in a bakery. She uses 250 milliliters of milk to make a loaf of bread. How many liters of milk will she need to make 15 loaves of bread?
Answer: 3.75 liters
Step-by-step explanation:
Zoe uses 250 milliliters of milk to make a loaf of bread.
If she needed to make 15 loaves therefore, she would do the following:
= 250 * 15 loaves
= 3,750 milliliters of milk
Then convert the above quantity to liters.
1 Liter = 1,000 milliliters.
3,750 milliters to liters is:
= 3,750 / 1,000
= 3.75 liters
