Olivia deposit 6952 in a savings account paying 3.72% interest to the nearest dollar how much money does Olivia have in total after 16 years
3x +2y=10 4x-y=6 using substitutional method
Answer:
( 2 , 2 )
Step-by-step explanation:
Solve the eqaution :
3x +2y=10
4x-y=6
Solve the eqaution for y :
3x + 2y = 10
y = -6 + 4x
Substitute for y : 3x + 2 ( -6 + 4x ) = 10
x = 10
Substitute for the value of x : x = 2
Substitute the given value of x into the eqaution
y = -6 + 4x : y = -6 + 4 × 2
Solve the eqaution: y = -6 + 4 × 2
solve the eqaution for y : y = 2
y = 2 A possible solution : the ordered solution pair is
( 2 , 2 )

a) Use Tuesday's results to estimate the
probability of Ben hitting the targe.
b) Use the total of the results to estimate the
probability of Ben of hitting the target.
c) Which estimate would give the most reliable probability?
A- the one from Tuesday or B - the one from the Total?
(1)
(1)
Total marks: 3
Answer:
0.6 ;
0.7
Reaukt in B will give a better estimate because it has a larger sample size (120) than the result on A ,with sample size (30)
Step-by-step explanation:
Probability of hitting the target using Tuesday's result :
P(hitting the target):
Probability = required outcome / Total possible outcomes
Required outcome = number of hits = 18
Total possible outcomes = number of throws =. 30
Hence, Probability of hitting the target using Tuesday's result : 18 / 30 = 0.6
B.)
Probability of hitting the target using Total result:
Required outcome = number of hits = 84
Total possible outcomes = number of throws =. 120
= 84 / 120
= 0.7
4 times a number increased by 10 is no less than 18, whats the equation please i need it less than 10 mins and pleasse dont put fake answer will get reported
Answer:
4x + 10 is less than or equal to 18
Hope this helps :) Good Luck!

hey yall again im really bad with triangles and theorems if someone could help me answer this question i will appreciate it. I need to figure out the postulate theorem
Answer and Step-by-step explanation:
The postulate of theorem that can be used to conclude the two triangles are congruent will be the ASA congruence postulate.
ASA means Angle Side Angle, in which two Angles in a triangle are congruent, and the side in between the two angles are congruent.
So, angle TXW is congruent to angle TWR, and the side that is in between is side WX, by the reflexive property of congruence.

An international company has 22,600 employees in one country. If this represents 16.3% of the company’s employees, how many employees does it have in total?
Round your answer to nearest whole number.
I will give brainliest
Answer:
sorry but I don't know the answer
Answer:
138650
Step-by-step explanation:
let the total nunber of employees be x
16.3% of x = 22 600
16.3
----- × x = 22 600
100
x = 22 600 × 100
-------------------
16.3
x = 138 650.3067
x = 138 650 (to the nearest whole number)
Explain step by step how to use the horizontal method the multiple the two polynomials
Answer:
Step-by-step explanation:
Multiply each term of the first polynomial with the second polynomial. Then combine the like terms.
(3a² + 5a - 2)* (5a² -3a + 4)
= 3a² *(5a² -3a + 4) + 5a*(5a² -3a + 4) - 2*(5a² -3a + 4)
=3a²*5a² - 3a*3a² + 4*3a² + 5a*5a² - 3a*5a + 4*5a + 5a²*(-2) - 3a*(-2) + 4*(-2)
=15a⁴ - 9a³ + 12a² + 25a³ - 15a² + 20a - 10a² + 6a - 8
= 15a⁴ - 9a³ + 25a³ + 12a² - 15a² - 10a² + 20a +6a - 8
= 15a⁴ + 16a³ - 13a² +26a - 8

Homework due at 12:00
I Need Help
Answer:
k = - 7.5
Step-by-step explanation:
Slope "m" of a line through points
( [tex]x_{1}[/tex] , [tex]y_{1}[/tex] )
( [tex]x_{2}[/tex] , [tex]y_{2}[/tex] )
is m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
Slopes of perpendicular lines are opposite reciprocal: [tex]m_{1}[/tex] [tex]m_{2}[/tex] = - 1
~~~~~~~~~~~~~~~
The slope of a line through points (0, 7) and (2, 10)
[tex]m_{1}[/tex] = [tex]\frac{10-7}{2-0}[/tex] = [tex]\frac{3}{2}[/tex]
Slope of perpendicular line through points (3, 5) and (k, 12) is [tex]m_{2}[/tex] = [tex]-\frac{2}{3}[/tex]
or [tex]m_{2}[/tex] = [tex]\frac{12-5}{k-3}[/tex]
[tex]\frac{7}{k-3}[/tex] = [tex]-\frac{2}{3}[/tex]
2(k - 3) = - 21
k - 3 = - 10.5
k = - 7.5
