Answer:
Step-by-step explanation:
larger radius R=87/2
smaller radius r=65/2
larger semi circle=1/2×2×π×R=π×R=π×87/2=87 π/2≈136.6 m
smaller semicircle =π×r=π×65/2=65 π/2≈102.1 m
length of track=87+65+136.6+102.1≈390.7 m
Answer:
29 bracelet
Step-by-step explanation:
150-36=114
114÷4=28.5≈29
Answer:
The equation that best describes the situation is:
Step-by-step explanation:
The initial amount of gravel is g.
Then we know that 400 pounds are added
Two orders of 900 pounds are sold and the gravel is removed from the mound. This is:
At the end of the day, the mound has 1,500 pounds of serious. This is:
The equation that best describes the situation is:
And
The regression equation is (d) log(y) = 0.064x + 1.706
<h3>How to determine the regression equation?</h3>
The table of values is given as:
x 2 3 4 5 6
y 73 77 85 101 133
Calculate the logarithm of the y values.
So, we have:
x 2 3 4 5 6
log(y) 1.86 1.89 1.93 2 2.12
Next, we enter the above values in a regression calculator.
From the calculator, we have the following summary:
- Sum of X = 20
- Sum of Y = 9.8
- Mean X = 4
- Mean Y = 1.96
- Sum of squares (SSX) = 10
- Sum of products (SP) = 0.63
The regression equation is then represented as:
log(y) = bx + a
Where:
b = SP/SSX = 0.64/10 = 0.064
a = MY - bMX = 1.96 - (0.064*4) = 1.706
So, we have:
log(y) = 0.064x + 1.706
Hence, the regression equation is (d) log(y) = 0.064x + 1.706
