X=first week
y=second week
z=third week
t=fourth week
18 more one 2nd week than 1st
x+18=y
x=y-18
3rd week, 4 less than 2 times as second
z=2y-4
4th week, 92
ttal=382
x+y+z+t=382
sub waht we know
x=y-18
y=y
z=2y-4
t=92
y-18+y+2y-4+92=382
conbine line terms
4y+70=382
minus 70 boht sides
4y=312
divide both sides by 4
y=78

Answer:
The player's height is 4.45 standard deviations above the mean.
Step-by-step explanation:
Z-score:
Measures how many standard deviations a measure X is above or below the mean.
His height converts to the z score of 4.45.
This means that:
The player's height is 4.45 standard deviations above the mean.
Answer:
$36
Step-by-step explanation:
Use the simple interest formula, I = prt
Plug in the interest rate, original amount of money, and number of years:
I = prt
I = (150)(0.08)(3)
I = 36
So, $36 in interest would be made
Answer:
1006
Step-by-step explanation:
Take proportion, p = 62%
n = (Z² * pq) / M.E²
Margin error = 0.03
p = 62% = 0.62
q = 1 - p = 1 - 0.62 = 0.38
Zcritical at 95% = 1.96
n = (1.96² * (0.62*0.38)) / 0.03²
n = 0.90508096 / 0.0009
n = 1005.6455
n = 1006
Sample size = 1006
Answer:
Step-by-step explanation:
From the picture attached,
In ΔABC and ΔGFE,
AC ≅ EG [Given]
BC ≅ EF [Given]
AB ≅ FG [Given]
By the SSS property of congruence, ΔABC ≅ ΔGFE
The two triangles are related by SSS property of congruence, so the triangles are congruent.
