By which number -7÷25 should be divided to get -1÷15
Answer:
Step-by-step explanation:
Set it up like an equation first:
[tex]\frac{\frac{-7}{25} }{x}=-\frac{1}{15}[/tex] and then bring up the lower fraction, flip it, and multiply:
[tex]-\frac{7}{25}*\frac{1}{x}=-\frac{1}{15}[/tex]
Simplify to
[tex]-\frac{7}{25x}=-\frac{1}{15}[/tex] and cross multiply to get
-25x = -105 and divide both sides by -25 to get that
[tex]x=\frac{105}{25}=\frac{21}{5}[/tex]
Solve for x. You must show all your work to receive credit.
Step-by-step explanation:
since the 2 arc angles cover the full circle, we know their sum must be 360°.
so,
23x - 5 + 37x + 5 = 360
60x = 360
x = 6
and so the angle at V = 5×6 + 17 = 30+17 = 47°
A correlation coefficient between average temperature and coat sales is most likely to be __________.
A correlation coefficient between average temperature and coat sales exists most likely to be between 0 and -1.
What is the correlation coefficient?The correlation coefficient exists as the exact measure that quantifies the power of the linear relationship between two variables in a correlation analysis. A correlation coefficient between average temperature and coat sales exists most likely to be between 0 and -1.
A negative correlation suggests two variables that tend to move in opposite directions. A correlation coefficient of -0.8 or lower displays a strong negative relationship, while a coefficient of -0.3 or lower signifies a very weak one.

A ship travels due west for 94 miles. It then travels in a northwest direction for 119 miles and ends up 173
miles from its original position. To the nearest tenth of a degree, how many degrees north of west (x) did it
turn when it changed direction? Show your work.
Using the law of cosines, the ship turned 72 degrees northwest when it changed direction.
What is the law of cosines?The law of cosines states that we can find the side c of a triangle as follows:
c² = a² + b² - 2abcos(C)
In which:
C is the angle opposite to side c.a and b are the lengths of the other sides.For this problem, the parameters are given as follows:
a = 94, b = 119, c = 173.
Hence the internal angle C is found as follows:
c² = a² + b² - 2abcos(C)
173² = 94² + 119² - 2 x 94 x 119cos(C)
22327cos(C) = -6932
cos(C) = -6932/22327
C = arccos(-6932/22327)
C = 108º.
The turning angle is the outside angle, which is supplementary with C, hence:
T = 180 - C = 180 - 108 = 72º.

Given 8 different toppings to choose from, how many 3-topping pizzas are possible?
Answer:
336 ways
Step-by-step explanation:
Use nPk which is [tex]\frac{n!}{(n-k)!}[/tex]. This is [tex]\frac{8!}{5!}[/tex]. This becomes 8×7×6 as the 8! and 5! cancel out. 8×7×6 is 336.
Total number of possible 3-topping pizzas are 336 ways.
How do you calculate the number of possible ways something can be arranged?In more general terms, if we have n items total and want to pick k in a certain order, we get: n! / (n – k)! And this is the permutation formula: The number of ways k items can be ordered from n items: P(n,k) = n (n – k)!
Given that,
Total number of items n = 8
number of picking item k = 3
Now,
p(n,k) = [tex]\frac{n!}{(n -k)!}[/tex]
p(8,5) = [tex]\frac{8!}{(8 -3)!}[/tex]
= [tex]\frac{8!}{5!}[/tex]
= [tex]\frac{8.7.6.5! }{5! }[/tex]

[tex]{ \qquad\qquad\huge\underline{{\sf Answer}}} [/tex]
Here we go ~
Let's calculate its discriminant :
[tex]\qquad \sf \dashrightarrow \: 4 {u}^{2} + 16u + 41 = 40[/tex]
[tex]\qquad \sf \dashrightarrow \: 4 {u}^{2} + 16u + 41 - 40 = 0[/tex]
[tex]\qquad \sf \dashrightarrow \: 4 {u}^{2} + 16u + 1 = 0[/tex]
Here, if we equate it with general equation,
a = 4b = 16 c = 1[tex]\qquad \sf \dashrightarrow \: disciminant = {b}^{2} - 4ac[/tex]
[tex]\qquad \sf \dashrightarrow \: d = (16) {}^{2} - (4 \times 4 \times 1) [/tex]
[tex]\qquad \sf \dashrightarrow \: d = (16) {}^{2} - (16) [/tex]
[tex]\qquad \sf \dashrightarrow \: d = 16(16 - 1)[/tex]
[tex]\qquad \sf \dashrightarrow \: d = 16(15)[/tex]
[tex]\qquad \sf \dashrightarrow \: d = 240[/tex]
Now, since discriminant is positive ; it has two real roots ~
The roots are :
[tex]\qquad \sf \dashrightarrow \: u = \dfrac{ - b \pm \sqrt{ d } }{2a} [/tex]
[tex]\qquad \sf \dashrightarrow \: u = \dfrac{ - 16\pm \sqrt{ 240 } }{2 \times 4} [/tex]
[tex]\qquad \sf \dashrightarrow \: u = \dfrac{ - 16\pm 4\sqrt{ 15 } }{8} [/tex]
[tex]\qquad \sf \dashrightarrow \: u = \dfrac{ 4(- 4\pm \sqrt{ 15 }) }{8} [/tex]
[tex]\qquad \sf \dashrightarrow \: u = \dfrac{ - 4\pm \sqrt{ 15 } }{2} [/tex]
So, the required roots are :
[tex]\qquad \sf \dashrightarrow \: u = \dfrac{ - 4 - \sqrt{ 15 } }{2} \: \: and \: \: \dfrac{ - 4 + \sqrt{15} }{2} [/tex]
