aev [14]2 years ago
8 0

x= 18

let me show you the workout

6x+1+12x-5=32

Combine like terms .Combine 6x+12=18x

18x-4=32 Subtract -4 from 32

18x=36 Divide by 18 and

X=16

Hoped this helped Im not sure if this is right

Test the claim that the proportion of people who own cats is larger than 40% at the 0.025 significance level. The null and alter
Alecsey [184]

Answer:

H 0 : p ≤ 0.4 H a : p > 0.4

And based on the alternative hypothesis we can conclude that we have a right tailed test

Step-by-step explanation:

Data given

n=300 represent the random sample size

\hat p=0.45 estimated proportion of people with cats

p_o=0.40 is the value that we want to test

\alpha=0.025 represent the significance level

z would represent the statistic

p_v represent the p value

Null and alternative hypothesis

We want to test if the true proportion of people with cats is higher than 0.4, so then the best alternative is:  

Null hypothesis:p\leq 0.4  

Alternative hypothesis:p > 0.4  

H 0 : p ≤ 0.4 H a : p > 0.4

And based on the alternative hypothesis we can conclude that we have a right tailed test

The statistic is given by:  

z=\frac{\hat p -p_o}{\sqrt{\frac{p_o (1-p_o)}{n}}} (1)  

Replacing we got:

z=\frac{0.45 -0.4}{\sqrt{\frac{0.4(1-0.4)}{300}}}=1.768

A round balloon has a diameter of 7 inches
gizmo_the_mogwai [7]

Answer:

The right answer is approximately 210.031 cubic inches. (Answer: E)

Step-by-step explanation:

First, we need to convert the diameter (D), in inches, of the round balloon to an entirely decimal mode:

D = 7\,in + \frac{3}{8}\,in

D = \frac{56 + 3}{8}\,in

D = \frac{59}{8}\,in

D \approx 7.375\,in

The volume of the balloon is modelled after the volume function of a sphere (V), in cubic inches:

V = \frac{\pi}{6}\cdot D^{3} (1)

If we know that D \approx 7.375\,in, then the volume of the round balloon is:

V = \frac{\pi}{6}\cdot D^{3}

V = \frac{\pi}{6} \cdot (7.375\,in)^{3}

V \approx 210.031\,in^{3}

Hence, the right answer is approximately 210.031 cubic inches.

Resolving horizontally .  Make  forces to the right positive 
resultant force =  70cos30-60cos60 = 60.62-60 = 0.62 lbs

resolve vertically  
resultant force =   120 sin60 - 70 sin30 = 103.92 - 35 = 68.92   lbs in downward direction

magnitude of the ressultant forsse = sqrt(68.92^2 + 0.62^2) =  68.92 lbs

direction of the force =  tan-1 (0.62 / 68.82) = 0.52 degrees east of south or

In Elizabeths town streets run east and west and avenues run north and south each street and avenue is one block apart. if eliza
emmainna [20.7K]

The <em><u>correct answer</u></em> is:

15 blocks.

Explanation:

"As the crow flies" means in a straight line.  This will be a diagonal line connecting the two locations.

Elizabeth's house can be represented by the ordered pair (1, 4), where the x-coordinate represents the street number and the y-coordinate represents the avenue number.  Using this same system, the restaurant is represented by the ordered pair (10, 16).  To find the length of the line segment that would connect the we use the distance formula:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}&#10;\\=\sqrt{(10-1)^2+(16-4)^2}&#10;\\=\sqrt{(9)^2+(12)^2}&#10;\\=\sqrt{81+144}=\sqrt{225}=15
