Answer:
2 hours
Step-by-step explanation:
First we need to know the distance Liam travelled using the bike.
If his speed was 8 mph and he travelled 3 hours, the distance travelled by bike is:
d = 8 * 3 = 24 miles
The total distance is 30 miles, so the remaining is:
30 - 24 = 6 miles
He travelled 6 miles with the speed of 3 mph, so the time walking is:
time = 6 / 3 = 2 hours
Answer:
H0 : μ = 15
H1 : μ < 15
−6.170774
Step-by-step explanation:
Given :
n=115, barx =11.3, and s=6.43
H0 : μ = 15
H1 : μ < 15
−0.053658 ;
The test statistic :
(xbar - μ) ÷ s/sqrt(n)
(11.3 - 15) ÷ (6.43/sqrt(115))
Test statistic = −6.170774
Rejection region :
Reject Null ; if
Tstatistic < Zcritical
The P value is 0.00001 ; using the p value from Z calculator
Since,
P value < α
0.00001 < 0.05
Reject the null

the answer is 3.75 I'll explain ,</span><span>here: 1.5 times 2 equals 3 now go to a different section and divide 1.5 by 2 then add the two together it will look kind of like this:</span>

Answer:
5 x 6
Step-by-step explanation:
The number of blocks of clay needed by Hyla is 30 blocks
<h3>What is area?</h3>
Area is the region bounded by a plane shape.
To calculate the number of blocks of clay needed by Hyla, we find the area of the bottom of the box and divide it by the area of the block.
Formula:
- n = LWH/lwh............... Equation 1
Where:
- n = Number of blocks of clay needed by Hyla
- L = Length of the bottom of the box
- W = Width of the bottom of the box
- H = Height of the box
- l = Length of the bottom of the block
- w = Width of the block
- h = Height of the block.
From the question,
Given:
- L = 24 cm
- W = 20 cm
- H = 2 cm
- l = 4 cm
- w = 4 cm
- h = 2cm
Substitute these values into equation 1
- n = (24×20×2)/(4×4×2)
- n = 30
Hence, The number of blocks of clay needed by Hyla is 30 blocks
