Answer:
2/15
Step-by-step explanation:
Step one:
given data
sample space
1 elephant,
4 bears,
3 cats, and
2 dogs.
sample size= 1+4+3+2= 10
Required:
By selecting without replacement, the probability that she chooses a bear both times
Step two:
the first event= Pr(bear)= 4/10= 2/5
the second event, the sample size is now 9 and the number of bears is now 3
Pr(bear)= 3/9= 1/3
Hence, the probability that she chooses a bear both times
= 2/5*1/3
=2/15
Helen had $330 in her savings account when Vince opened a savings account with zero dollars.
Helen deposited $30 into her account each week for x weeks.
Vince deposited $50 into his account each week for x weeks.
The accounts did not earn interest.
Which inequality represents this situation when the amount of money in Helen's account was greater than the amount of money in Vince's account?
A.
30x>330+50x
B.
50x 330+30x
I think the answer is 30x+330>50x
Step-by-step explanation:
for the option A it was slightly changed,
cause the $30 was deposited by helen not Vince.
so check that well

Answer:
=36n-175
Step-by-step explanation:
Identify The domain of the rational function, g(x)= 1/x+3
A (-∞, ∞)
B (-∞, 3)U(3, ∞)
C (-∞, -3]U[-3, ∞)
D (-∞, -3)U(-3, ∞)
Answer:
The domain is (-∞ , -3) ∪ (-3, ∞) ⇒ D
Step-by-step explanation:
The domain of the rational fraction is the values of x which make the fraction defined. That means the domain does not contain the values of x which make the denominator equal to 0.
∵ g(x) = [tex]\frac{1}{x+3}[/tex]
∴ The denominator = x + 3
→ Equate the denominator by 0
∵ x + 3 = 0
→ Subtract 3 from both sides
∴ x + 3 - 3 = 0 - 3
∴ x = -3
→ That means the domain can not have -3 because it makes the denominator
equal to 0
∴ The domain is all values of real numbers except x = -3
∴ The domain = {x : x ∈ R, x ≠ -3}
∴ The domain = (-∞ , -3) ∪ (-3, ∞)
A high school track team's long jump record is 24 ft 9 1/4 in. This year, Arthur's best long jump is 24 ft 3 1/2 If long jumps are measured to the nearest quarter inch, how much farther must jump to break the record?
Answer:
5 3/4 inches
Step-by-step explanation:
Given that :
Long jump record held = 24 ft 9 1/4 in
Arthur's best long jump record = 24 ft 3 1/2 in
How much further must ARTHUR jump to brake the record :
Long jump record - Arthur's best jump
[24 ft 9 1/4 in] - [24 ft 3 1/2 in]
24 ft - 24 ft = 0
9 1/4 in - 3 1/2 in
37 / 4 in - 7 /2 in
L. C. M of 4 and 2 = 4
(37 - 14) / 4 inches
23 /4 inches
= 5 3/4 inch
Answer: 5 3/4 inches

A bottle is filled with 635 g of olive oil which has a density of 0.96 g/cm3. What is the volume of the olive oil ?
Answer:
The volume of the olive oil is 661.4583 cm³
Step-by-step explanation:
The rule of the density of an object is d = M ÷ V, where
M is the mass of the objectV is the volume of the object∵ A bottle is filled with 635 g of olive oil
∴ M = 635 g
∵ The olive oil has a density of 0.96 g/cm³
∴ d = 0.96 g/cm³
→ Substitute them in the rule above
∵ 0.96 = 653 ÷ V
→ Multiply both sides by V
∴ 0.96 V = 635
→ Divide both sides by 0.96
∴ V = 661.4583 cm³
∴ The volume of the olive oil is 661.4583 cm³

16) Avery selects two chips from a bag without looking at them. The bag has 5 green chips, 3 red chips, and 7 blue chips. What is the probability that he selects a red and then a blue chip (without replacing)? * 6 points 2/3 7/75 1/10 2/45
Answer: [tex]\dfrac{1}{10}[/tex]
Step-by-step explanation:
Given: The bag has 5 green chips, 3 red chips, and 7 blue chips.
Total chips = 5+3+7= 15
Number of ways to select a red and then a blue chip = 3 x 7 = 21
Total number of ways to select 2 chips without replacement = 15 x 14 =210
Required probability = [tex]\dfrac{\text{favorable outcomes}}{\text{Total outcomes}}[/tex]
[tex]=\dfrac{21}{210}=\dfrac{1}{10}[/tex]
So, the probability that he selects a red and then a blue chip (without replacing) = [tex]\dfrac{1}{10}[/tex]

Answer
85%
Step-by-step explanation:
34/40=0.85
Answer:
85%
Step-by-step explanation:
Easy way to solve this is just to divide 34 and 40.
34÷40=0.85.
Then you multiply 0.85 by 100 to get the decimal to the front.
0.85 x 100=85

The missing value of m.
Solution:
We have,
[tex]\Delta ABC\sim \Delta QRS[/tex]
Corresponding parts of similar triangles are proportional.
[tex]\dfrac{AB}{QR}=\dfrac{AC}{QS}[/tex]
Putting the given values, we get
[tex]\dfrac{m}{10}=\dfrac{2}{4}[/tex]

Multiply both sides by 10.
[tex]\dfrac{m}{10}\times 10=\dfrac{1}{2}\times 10[/tex]
[tex]m=5[/tex]
Therefore, the value of m is 5.

What are the coordinates of the vertices of the triangle under the translation (x, y) (x + 2, y + 3)? (-4, 5), (3, 4), (0, 0) (5, -4). (4, 3), (-1, 2) (6, -5), (5, 2), (1, -1) (-5, 6), (2, 5), (-1, 1)
Answer:
(2, 5), (-5, 6) and (-1, 1)
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, dilation and translation.
If a point A(x,y) is translated a units right and b units up, the new location is at A'(x + a, y + b).
From the image attached, the location of the vertices of the triangle is at (0,2), (-7, 3) and (-3, -2). If the triangle is under the translation (x, y) ⇒ (x + 2, y + 3), the new location of the vertices would be at (2, 5), (-5, 6) and (-1, 1)
Betty had 1/3 yard of ribbon. She used 1/2 of it. How many yards of ribbon did she use?
a. 6 yd
b. 1/6 yd
c. 2/3 yd
d 3/2 yd
Answer:
b. 1/6 yd
Step-by-step explanation:
When Betty used 1/2 OF the 1/3 yards she has she has to multiple those. It's easier to put it in a sentence in my opinion because then you can see the "of" in the sentence which means to multiply. Hope this helps!
