rearrange w=5(3a-b) + 2 to make a the subject
Answer:
w=15a-5b+2
w+5b-2=15a
(w+5b-2)/15=a
Step-by-step explanation:
The value of a in the expression w = 5(3a - b) + 2 is a = (1 + 5b - 2)/15.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given an expression w = 5(3a - b) + 2.
Now to make 'a' the subject is the same as finding the value of a.
w = 5(3a - b) + 2.
w = 15a - 5b + 2.
w + 5b - 2 = 15a.
a = (1 + 5b - 2)/15.

A recent poll of 1500 new home buyers found that 60% hired a moving company to help them move to their new home. Find the margin of error for this poll if we want 95% confidence in our estimate of the percentage of new home buyers who hired movers.
Answer:
The margin of error M.O.E = 2.5%
Step-by-step explanation:
Given that;
The sample size = 1500
The sample proportion [tex]\hat p[/tex] = 0.60
Confidencce interval = 0.95
The level of significance ∝ = 1 - C.I
= 1 - 0.95
= 0.05
The critical value:
[tex]Z_{\alpha/2} = Z_{0.05/2} \\ \\ Z_{0.025} = 1.96[/tex] (From the z tables)
The margin of error is calculated by using the formula:
[tex]M.O.E = Z_{\alpha/2} \times \sqrt{\dfrac{\hat p(1 -\hat p)}{n}}[/tex]
[tex]M.O.E = 1.96 \times \sqrt{\dfrac{\hat 0.60(1 -0.60)}{1500}}[/tex]
[tex]M.O.E = 1.96 \times \sqrt{\dfrac{0.24}{1500}}[/tex]
[tex]M.O.E = 1.96 \times \sqrt{1.6 \times 10^{-4}}[/tex]
M.O.E = 0.02479
M.O.E ≅ 0.025
The margin of error M.O.E = 2.5%

Step-by-step explanation:
.Write the vertex and indicate if the graph opens up or down. y = 2x2 + 8x + 3
A. (2,5) down
B. (-2,5) up
C. (-2,-5) down
D. (-2,-5) up
Given:
The equation of the parabola is
[tex]y=2x^2+8x+3[/tex]
To find:
The vertex and check whether it opens up or down.
Solution:
We have,
[tex]y=2x^2+8x+3[/tex]
Here, leading coefficient is 2 which is a positive number. So, the parabola opens up.
The vertex of parabola [tex]f(x)=ax^2+bx+c[/tex] is
[tex]\left(\dfrac{-b}{2a},f(\dfrac{-b}{2a})\right)[/tex]
Here, a=2, b=8 and c=3.
[tex]\dfrac{-b}{2a}=\dfrac{-8}{2(2)}[/tex]
[tex]\dfrac{-b}{2a}=\dfrac{-8}{4}[/tex]
[tex]\dfrac{-b}{2a}=-2[/tex]
Putting x=-2 in the given equation.
[tex]y=2(-2)^2+8(-2)+3[/tex]
[tex]y=2(4)+(-16)+3[/tex]
[tex]y=8-16+3[/tex]
[tex]y=-5[/tex]
So, the vertex of the parabola is at (-2,-5) and parabola opens up.
Therefore, the correct option is D.

g If the quantity of helium in a weather balloon in increased by a factor of 5 at constant temperature and pressure, by how much does the volume of the balloon change? Decrease by 2 times Increase by 5 times Decrease by 5 times Increase by 2 times
Answer:
Increase by 5 times
Step-by-step explanation:
Given that from the ideal gas law;
PV = nRT
P= pressure
V= volume
n= number of moles
R= gas constant
T = temperature
It the follows that;
V= nRT/P
When the number of moles (quantity of helium) is increased by a factor of 5 while temperature and pressure remain constant, we can write;
PV = 5nRT
V = 5nRT/P
Hence the volume increases by a factor of 5.
