so just multiply
boys= 8/9 x 270 = 240
Answer:
240
Step-by-step explanation:
270 * 8/9 = 240
so 240:270 is equivalent to 8:9
Which point on the number line below represents a value of 0.75?
Answer:
Point C
Step-by-step explanation:
Each of the lines are counted by 5 and if counting carefully, C would be 0.75, or, 3/4
Point C on the number line below represents a value of 0.75.
What is Coordinates?A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinates.
Given that;
To find point on the number line which represents a value of 0.75..

Each algorithm is applied to a group of 52 sample problems. The new algorithm completes the sample problems with a mean time of 24.04 hours. The current algorithm completes the sample problems with a mean time of 24.52 hours. The standard deviation is found to be 5.769 hours for the new algorithm, and 5.556 hours for the current algorithm. Conduct a hypothesis test at the 0.05 level of significance of the claim that the new algorithm has a lower mean completion time than the current algorithm.
Answer:
Therefore we fail to reject the Null hypothesis [tex]H_0[/tex]
Because the is no sufficient evidence to support the claim of the alternative hypothesis [tex]H_a[/tex]
Step-by-step explanation:
From the question we are told that
Sample size [tex]n_1 =52[/tex]
Mean time 1 [tex]\=x_1=24.04\ hours[/tex]
Mean time 2 [tex]\=x_2=24.52\ hours[/tex]
Standard deviation [tex]\partial _1=5.769[/tex]
Standard deviation [tex]\partial _2=5.556[/tex]
Level of significance 0.05
The null hypothesis is [tex]H_o: \mu_1=\mu_2[/tex]
Alternative hypothesis [tex]H_a: \mu_1<\mu_2[/tex]
Generally the test statistics is mathematically represented as
[tex]Z= \frac{\=x_1-\=x_2}{\sqrt{\frac{\sigma_1^2}{n_1}+\frac{\sigma_2^2}{n_2}}}[/tex]
[tex]Z= \frac{24.04-24.52}{\sqrt{\frac{5.769^2}{52}+\frac{5.5562^2}{52}}}[/tex]
[tex]Z= -0.4321583379[/tex]
[tex]Z= -0.43[/tex]
From Table the Z-critical value at [tex]\alpha =0.05\ is\ -1.6449[/tex]
Therefore
Zcal> Zcritical
(-0.43)=(-1.645)
Generally we fail to reject the null hypothesis [tex]H_0[/tex] at [tex]\alpha = 0.05[/tex]
Therefore we fail to reject the[tex]H_0[/tex]
Because the is no sufficient evidence to support the claim of [tex]H_a[/tex]

What is the common ratio of the geometric sequence 16, 24, 36, 54, ...?
2/3
1
8
3/2
Answer:
r = 3/2
Step-by-step explanation:
The common ratio (r) is the number that, when multiplied by the previous (n-1) term, gives the nth term of the geometric sequence ([tex]a_{n} =a_{n-1}*r[/tex]). To find the common ratio, we can take any term and divide it by its preceding term (rearrange the formula to get [tex]r=\frac{a_{n}}{a_{n-1}}[/tex]). If we take 24 and divide it by 16, we get the common ratio of 3/2 ([tex]r=\frac{24}{16}[/tex], [tex]r=\frac{3}{2}[/tex]). Hope this helps.

Point A is located at (8, 7) and Point B is located at (0, 5) find the midpoint of line segment overline AB .
Answer:
The midpoint of the line segment D = ( 4, 6)
Step-by-step explanation:
Explanation:-
Given points are A(8,7) and B(0,5)
The midpoint of line segment overline AB
Let 'D' be the midpoint of AB
[tex]D= (\frac{x_{1} + x_{2} }{2} , \frac{y_{1} +y_{2} }{2} )[/tex]
[tex]D = (\frac{8+0}{2} , \frac{7+5}{2} )[/tex]
[tex]D = (\frac{8}{2} , \frac{12}{2} )[/tex]
The midpoint of the line segment
D = ( 4, 6)

Discounts and what is the outcome
Answer:
with discount+tax= $23.15
Step-by-step explanation:
board game is 25
discount: 15%
tax: 7.5%
discount means you take off that amount
tax means you add that amount
discount: 15% off
tax: +7.5%
to find 15% of 25 multiply 25 by 15% (15/100=0.15)
25*0.15
= 3.75
then subtract that from 25
25-3.75
=21.25
tax:
0.075*25
=1.875
~1.9
21.25+1.9
=23.15
