Please can y’all help. I’m terrible at maths.
Answer:
x = 49°, and y = 63°
Step-by-step explanation:
Starting with x, you can see that it is in a corner where two lines cross each other. That means that x is equal to the angle on the other side of that intersection, which we are given. x then, is equal to 49°
And with y, You'll notice that is formed with two lines, a horizontal one and and a diagonal one. At he bottom of the shape you can see another horizontal one intersecting with the same diagonal one. Notice also that the two lines use the ">" symbol, noting that the lines are parallel. Because those lines are parallel, the angles between each of those and the diagonal one are the same. This tells us that y is equal to 63°

In the song, 25 percent of the class weighed less than 6 pounds, 1 ounce at birth. 6 pounds, 1 ounce is the
Answer:
Step-by-step explanation:
A
For the considered case, the weight 6 pound 1 ounce will be taken as : Option C: Lower quartile.
What are quartiles?When we get data which can be compared relatively with each other, for finding quartiles, we arrange them in ascending or descending order.
Quartiles are then selected as 3 points such that they create four groups in the data, each groups approximately possessing 25% of the data.
Lower quartile, also called first quartile has approx 25% in its left partition, and on its right lies approx 75% of the data.
Similarly, second quartile (also called median) is approximately in mid of the data.
Third quartile (also called upper quartile) has approx 75% in its left partition, and on its right lies approx 25% of the data.
Left to right is said in assumption that data was arranged increasingly from left to right
For this case, it is said that 25% of the class weighted less than 6 pounds 1 ounce. That means it is first quartile or say lower quartile.
Thus, for the considered case, the weight 6 pound 1 ounce will be taken as : Option C: Lower quartile.

How many different passwords can be made if it is three letters, followed by two digits, followed by a letter?
(Repetition is allowed.) Use the fundamental counting principle.
Infinitely many passwords can be made.
There are 45,697,600 different passwords.
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Since, Fundamental counting principle states that if there are p ways to do a thing, and q ways to do another thing, and these two things are independent,
Then, there are p x q ways to do both things.
Hence, In this question:
3 letters, each with 26 possible options(ways).
Two digits, each with 10 possible options.
One digit, with 26 possible options.
And, Each digit/letter is independent,
Thus, Number of ways are;
26 x 26 x 26 x 10 x 10 x 26 = 45,697,600
Thus, There are 45,697,600 different passwords are possible,

According to the eScience Lab Manual for Lab 1, Experiment 3, you need to prepare 65 ml of 60% soda/syrup prescription. To do this you can use the 80% soda solution and the syrup solution (0% strength) that you have in inventory. How many mls of soda solution do you need to create this final solution?
Answer:
16.25 mL
Step-by-step explanation:
Since we are mixing from the syrup in the inventory, we can say that the syrup in the inventory must be equal to that in the final solution. Thus, we will use the dilution equation to solve for the Initial volume;
Dilution equation is;
V₁C₁ = V₂C₂
Where;
V₁ is initial volume
C₁ is initial concentration or initial molarity
V₂ is final volume
C₂ is final concentration of final molarity
We are given;
C₁ = 80% = 0.8
C₂ = 60% = 0.6
V₂ = 65 mL
Making V₁ the subject in the dilution equation, we have;
V₁ = (V₂C₂)/C₁
V₁ = (65 × 0.6)/0.8
V₁ = 48.75 mL of inventory syrup
Since we have 48.75 mL of inventory syrup and the dilute solution is 65 ml, then the volume of soda solution required = 65mL - 48.75 mL = 16.25 mL

Answer:
Step-by-step explanation:
Let's get the equation first and then look at the circle when it has been graphed.

the volume of a sphere is increasing at a rate of 2cm^3/sec. Find the rate of change of its surface area when its volume is 256pi/3 cm^3.
Answer:
The rate of change of the surface area of the sphere is 0.99 cm²/s.
Step-by-step explanation:
The surface area (A) of a sphere is given by:
[tex] A = 4\pi r^{2} [/tex]
If we derivate the above equation with respect to the time we have:
[tex] \frac{dA}{dt} = 4\pi (2r)\frac{dr}{dt} [/tex]
[tex] \frac{dA}{dt} = 8\pi r\frac{dr}{dt} [/tex] (1)
Where:
r: is the radius
We need to find [tex]\frac{dr}{dt}[/tex] and r.
From the volume we can find the radius:
[tex] V = \frac{4}{3}\pi r^{3} = 256 \frac{\pi}{3} cm^{3} [/tex]
[tex] r = \sqrt[3]{\frac{3V}{4\pi}} = \sqrt[3]{\frac{3*256*\frac{\pi}{3}}{4\pi}} = 4 cm [/tex]
And by derivating the volume of the sphere with respect to the time we can calculate [tex]\frac{dr}{dt}[/tex]:
[tex]\frac{dV}{dt} = \frac{4}{3}\pi(3r^{2})\frac{dr}{dt}[/tex]
[tex]\frac{dV}{dt} = 4\pi r^{2}\frac{dr}{dt}[/tex]
[tex] \frac{dr}{dt} = \frac{\frac{dV}{dt}}{4\pi r^{2}} = \frac{2}{4\pi(4)^{2}} = 0.0099 cm/s [/tex]
Now, we can calculate the rate of change of the surface area (equation 1):
[tex] \frac{dA}{dt} = 8\pi r\frac{dr}{dt} = 8\pi*4*0.0099 = 0.99 cm^{2}/s [/tex]
Therefore, the rate of change of the surface area of the sphere is 0.99 cm²/s.

A wedding website states that the average cost of a wedding is $25,809. One concerned bride hopes that the average is less than reported. To see if her hope is correct, she surveys 46 recently married couples and finds that the average cost of weddings in the sample was $24,638. Assuming that the population standard deviation is $5531, is there sufficient evidence to support the bride’s hope at the 0.10 level of significance?
Step 1 of 3 : State the null and alternative hypotheses for the test. Fill in the blank below.
H0Ha: μ=25,809: μ⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯25,809
Step 2 of 3 : Find the test statistic
Step 3 of 3 : What is the conclusion?
Answer:
1)
Null hypothesis H₀ : μ = 25,809
Alternative hypothesis H₁ : μ < 25,809
2) Test Statistic = -1.44
3) Conclusion:
The result is significant, there is sufficient evidence to support the bride’s hope at the 0.10 level of significance.
Step-by-step explanation:
Given the data in the question;
Sample mean x" = 24,638
sample size n = 46
standard deviation σ = 5531
level of significance ∝ = 0.10
NULL and ALTERNATIVE HYPOTHESIS
Null hypothesis H₀ : μ = 25,809
Alternative hypothesis H₁ : μ < 25,809
TEST STATISTICS
Z = (x"-μ) / σ√n
we substitute
Z = (24,638 - 25,809) / (5531/√46)
Z = -1171 / 815.5
Z = -1.44
Test Statistic = -1.44
Now, from normal z-table;
P-value = P( Z < -1.44 ) = 0.0749
P-value = 0.0749
Since P-value ( 0.0749 ) is less than level of significance ( 0.10 ), we reject H₀.
Conclusion:
The result is significant, there is sufficient evidence to support the bride’s hope at the 0.10 level of significance.
