Answer:
x ≈ ±2.1407
Step-by-step explanation:
0.5(x⁴ - 9) + 15 = 0
Distribute the 0.5 across the parentheses.
0.5x⁴ - 4.5 + 15 = 0
Combine the constants.
0.5x⁴ + 10.5 = 0
Subtract 10.5 from both sides.
0.5x⁴ = -10.5
Divide both sides by 0.5.
x⁴ = 21
Take the fourth root of 21.
⁴√21 ≈ ±2.1407
x ≈ ±2.1407

Chipotle Burritos are normal distributed with a mean length of 200mm and a standard deviation of 8mm. What is the probability that a burito picked at random is shorter than 190mm?
Answer: 0.1056
Step-by-step explanation:
Given: Chipotle Burritos are normal distributed with
Mean = 200 mm
Standard deviation = 8 mm
Let x be the length of a random burrito.
The probability that a burrito picked at random is shorter than 190mm will be :
[tex]P(x<190)=P(\dfrac{x-\mu}{\sigma}<\dfrac{190-200}{8})\\\\=P(z<-1.25)\ \ \ [z=\dfrac{x-\mu}{\sigma}]\\\\=1-P(z<1.25)\\\\=1-0.8944\\\\=0.1056[/tex]
Hence, the probability that a burrito picked at random is shorter than 190mm is 0.1056.

There are 19 oak trees in a park. Workers will plant more oak trees today. When the workers are finished there will be 56 oak trees in the park. How many oak trees did they plant today?
Given:
There are 19 oak trees in a park.
There will be 56 oak trees in the park the plantation.
To find:
How many oak trees did they plant today?
Solution:
We have,
Initial number of oak trees = 19
Number of trees after plantation = 56
Now, the number of oak trees they plant today is
New trees = Number of trees after plantation - Initial number of oak trees
= 56 - 19
= 37
Therefore, they did plant 37 oak trees today.

1/6 dividend by 3 =
Answer:
1. 1/18
2.1/18
Step-by-step explanation:
In order to multiply fractions, you just multiply it straight out. Numerator to numerator, denominator to denominator.
1*1=1
6*3=18
So, the answer is 1/18.
To divide fractions, you flip the second number. If the number is 3, you flip the 3 to the denominator to make 1/3. Then, you multiply using the rule above.

which similarity theorem can be used to prove the two triangles below similar ?
A: sss similarity theorem
B. aa similarity theorem
C. sas similarity theorem
D. not similar
The similarity theorem that proves the two given triangles are similar is: B. AA similarity theorem.
Recall:
The angle-angle similarity theorem (AA) states that if two angles in one triangle are of the same measure with two corresponding angles in another triangle, both triangles are similar to each other.
In the image given:
[tex]\angle F[/tex] in [tex]\triangle ETF[/tex] is congruent to [tex]\angle U[/tex] in [tex]\triangle VTU[/tex] ([tex]\angle F = \angle U = 78[/tex])
[tex]\angle ETF = \angle VTU[/tex] (vertical angles are equal)
This implies that two angles in [tex]\triangle ETF[/tex] are congruent to two corresponding angles in [tex]\triangle VTU[/tex].
Therefore, both triangles can be proven to be similar by the angle-angle similarity theorem (AA).

Nancy has 1/3 of a cup of strawberries. She wants to share them with her 4 friends. How much will each of her friends get?
isabels class has collected 90 cans in a food drive they plan to sort the cans into n bags, with an equal number of cans in each bag. write an expression to show how many cans there will be in each bag.
Answer:
cn=90, so long as c and n are whole numbers
Step-by-step explanation:
There are two variables in this equation you have here. One, n the number of bags, has already been given to you, because there can be any number of bags. The other, weĺl call it c, is the number of cans in each bag. Because there could be any number of bags, and the number of cans needed in each one is also a variable, you are left with more than one option. Any solution will work so long as the number of cans, c, per bag, n, is equal to the total, 90. There could be 9 cans in 10 bags, or 10 cans in 9 bags, or 15 cans in 6 bags or vice versa. The only way to define it for one answer is to have a set number of bags or cans per bag. Hope this helps!
Given that ΔABC ∼ΔDEF, m∠A = 108 degrees and m∠E = 40 degrees. Find m∠F. Type ONLY the number of degrees.
Answer:
∠F = 32°
Step-by-step explanation:
ΔABC & ΔDEF are similar triangles. So, corresponding angles of both triangles are congruent
∠D = ∠A = 108
∠B = ∠E = 40
∠C = ∠F
In ΔDEF,
∠D +∠E + ∠F = 180 {Angle sum property of triangle}
108 + 40 + ∠F = 180
148 +∠F = 180
∠F = 180 - 148
∠F = 32°

Suppose that 2000 is invented at a rate of 3.5%, compounded semiannually. Assuming that no withdrawals are made, find the total amount after 4 years. Do not round any interminate computations, And round your answer to the nearest cent.
Answer:
$2,297.76
Step-by-step explanation:
Present value: P = 2000
Future value: F
Annual interest rate: r = 3.5% = 0.035
Time: t = 4 years
Number of compounding periods per year: n = 2
[tex] F = P(1 + \dfrac{r}{n})^{nt} [/tex]
[tex] F = 2000(1 + \dfrac{0.035}{2})^{2 \times 4} [/tex]
[tex] F = 2000(1 + 0.0175)^{8} [/tex]
[tex] F = 2000(1.0175)^{8} [/tex]
[tex] F = 2000(1.148881783) [/tex]

Write an equivalent expression by distributing the "-−" sign outside the parentheses:
-(-1.5q+5r)+2
Answer:
1.5q - 5r = 2
Step-by-step explanation:
All you need to do here is negate each term inside the brackets, which allows you to get rid of the minus sign and the brackets.
-(-1.5q + 5r) = 2
is exactly the same as saying:
-1 × (-1.5q + 5r) = 2
And if we multiply each term in the brackets by negative one, we get:
(1.5q - 5r) = 2
And now the brackets can go, leaving you with:
1.5q - 5r = 2

Which equation would best help solve the following problem? The height of a triangle is 5 m less than its base. The area of the triangle is 42 m² What is the length of the base?
Answer:
[tex]\boxed{\displaystyle 42=\frac{1}{2}x(x-5)}[/tex]
The second choice is correct
Step-by-step explanation:
Area of a Triangle
Given a triangle of base B and height H, the area is calculated by the formula:
[tex]\displaystyle A=\frac{1}{2}BH[/tex]
Let's call x=base of a triangle
Since the height of the triangle is 5 m less than the base:
x - 5 = height of the triangle.
Thus, the area is
[tex]\displaystyle A=\frac{1}{2}x(x-5)[/tex]
The value of the area is given as A=42 square meters, thus:
[tex]\boxed{\displaystyle 42=\frac{1}{2}x(x-5)}[/tex]
The second choice is correct
