Answer:

ρ_air = 0.15544 kg/m^3

Step-by-step explanation:

Solution:-

- The deflated ball ( no air ) initially weighs:

                             m1 = 0.615 kg

- The air is pumped into the ball and weight again. The new reading of the ball's weight is:

                            m2 = 0.624 kg

- The amount of air ( mass of air ) pumped into the ball can be determined from simple arithmetic between inflated and deflated weights of the ball.

                           m_air = Δm = m2 - m1

                           m_air = 0.624 - 0.615

                           m_air = 0.009 kg

- We are to assume that the inflated ball takes a shape of a perfect sphere with radius r = 0.24 m. The volume of the inflated ( air filled ) ball can be determined using the volume of sphere formula:

                         V_air = 4*π*r^3 / 3

                         V_air = 4*π*0.24^3 / 3

                         V_air = 0.05790 m^3  

- The density of air ( ρ_air ) is the ratio of mass of air and the volume occupied by air. Expressed as follows:

                         ρ_air = m_air / V_air

                         ρ_air = 0.009 / 0.05790

Answer:            ρ_air = 0.15544 kg/m^3

Answer:2x-1=0

Step-by-step explanation:

x=1/2

Cross multiply

2x=1

Subtract 1 from both sides

2x-1=1-1

2x-1=0

The equation below has a solution of x= 1/2 will be 2x-1=0.Option A is correct.

A mathematical statement consisting of an equal symbol between two algebraic expressions with the same value is known as an equation.

Given expression;

x=1/2

2x=1

Take 1 away from both sides.

2x-1=1-1

2x-1=0

The equation below has a solution of x= 1/2 will be 2x-1=0.

Hence, option A is correct.

Answer:

$733.29. Simply because you take $896•0.12 to find the 12% off and then you take that subtracted by the starting total. After you get the 12% off then you multiply that number by .07 to get the sales tax. After you find that then you add the number you got after multiplying to the number you got after taking off the 12%.

Answer:

It is 124 degrees.

Step-by-step explanation:

You square each coordinate like this:

sqrt(x^2+y^2 )

You will end up getting sqrt(53 and sqrt(10.

Then find the dot product which is -6+-7=-13.

Then cos^-1(-13/sqrt53*sqrt10)

=124 degrees

Answer:

[tex]z=\frac{0.467 -0.4}{\sqrt{\frac{0.4(1-0.4)}{150}}}=1.675[/tex]  

Now we can calculate th p value using the alternative hypothesis with the following probability:

[tex]p_v =2*P(z>1.675)=0.0939[/tex]  

Since the p value is higher than the significance level given of 0.05 we have enough evidence to FAIL to reject the null hypothesis and we can conclude that the true proportion of Type A donations  is not significantly different from 0.4 or 40% at 5% of significance.

Step-by-step explanation:

Information given

n=150 represent the random sample taken

X=70 represent the samples with Type A blood

[tex]\hat p=\frac{70}{150}=0.467[/tex] estimated proportion of samples with Type A blood

[tex]p_o=0.4[/tex] is the value to verify

[tex]\alpha=0.05[/tex] represent the significance level

zwould represent the statistic

[tex]p_v[/tex] represent the p value

System of hypothesis

We want to verify if the actual percentage of Type A donations differs from 40%, then the system of hypothesis are:  

Null hypothesis:[tex]p=0.4[/tex]  

Alternative hypothesis:[tex]p \neq 0.4[/tex]  

The statistic is given by:

[tex]z=\frac{\hat p -p_o}{\sqrt{\frac{p_o (1-p_o)}{n}}}[/tex] (1)  

Replacing the info given we got:

[tex]z=\frac{0.467 -0.4}{\sqrt{\frac{0.4(1-0.4)}{150}}}=1.675[/tex]  

Now we can calculate th p value using the alternative hypothesis with the following probability:

[tex]p_v =2*P(z>1.675)=0.0939[/tex]  

Since the p value is higher than the significance level given of 0.05 we have enough evidence to FAIL to reject the null hypothesis and we can conclude that the true proportion of Type A donations  is not significantly different from 0.4 or 40% at 5% of significance.

Answer:

[tex]c = \frac{A}{12h} - b[/tex]

Step-by-step explanation:

Okay, so the goal is to isolate c on one side with all the other terms on the other side. So, let's start by dividing both sides with 12h. After we do that, we will be left with [tex]\frac{A}{12h} = b+c[/tex]. Now, we can subtract both sides by b, and we will be left with [tex]\frac{A}{12h} - b = c[/tex]. Yay! We've now isolated c and that is our final answer!

Answer:

[tex]360in^2[/tex] is your surface area

Step-by-step explanation:

I attached a picture on how to label the box.

The surface area is all the areas of the like shapes combined.

Since there are four like rectangles and two like squares it can be written like this:

[tex]A=2l_1w_1+4l_2w_2[/tex]

(l1w1 can be used for the squares and l2w2 can be used for the rectangles).

Now it's a matter of plugging in values.

[tex]A=2(6)(6)+4(12)(6)\\A=2(36)+4(72)\\A=72+288\\A=360in^2[/tex]

Answer:

H0: μ ≤ 68,800

H1: μ > 68,800

Step-by-step explanation:

The null hypothesis (H0) tries to show that no significant variation exists between variables or that a single variable is no different than its mean. While an alternative Hypothesis (H1) attempt to prove that a new theory is true rather than the old one. That a variable is significantly different from the mean.

For the case above;

The Null hypothesis is that the average attendance at games is less than or equal to 68,800.

H0: μ ≤ 68,800

The alternative hypothesis is that the average attendance at games is over 68,800.

H1: μ > 68,800

H₀: μ ≤ 68,800 H₁: μ > 68,800. Then the correct option is D.

In null hypotheses, there is no relationship between the two phenomenons under the assumption, or it is not associated with the group. And in alternative hypotheses, there is a relationship between the two chosen unknowns.

The Null hypothesis is that the average attendance at games is less than or equal to 68,800.

H₀: μ ≤ 68,800

The alternative hypothesis is that the average attendance at games is over 68,800.

H₁: μ > 68,800

Then the correct option is D.
