I think it is d=5 because when you add them all up and divide by 5 it is 5
Answer:
y = 19.1 cm
Step-by-step explanation:
From the question given above, the following data were obtained:
Angle θ = 47 °
Opposite = 14 cm
Hypothenus = h =?
The value of h can be obtained by using the sine ratio. This can be obtained as follow:
Sine θ = Opposite / Hypothenus
Sine 47 = 14 / h
0.7314 = 14 / h
Cross multiply
0.7314 × y = 14
Divide both side by 0.7314
y = 14 / 0.7314
y = 19.1 cm
Answer:
P(X > 112) = 0.21186.
Step-by-step explanation:
We are given that the random variable X is normally distributed, with mean
= 100 and standard deviation
= 15.
Let X = <u><em>a random variable</em></u>
The z-score probability distribution for the normal distribution is given by;
Z =
~ N(0,1)
where,
= population mean = 100
= standard deviaton = 15
Now, the probability that the random variable X is greater than 112 is given by = P(X > 112)
P(X > 112) = P(
>
) = P(Z > 0.80) = 1- P(Z
0.80)
= 1 - 0.78814 = <u>0.21186</u>
The above probability is calculated by looking at the value of x = 0.80 in the z table which has an area of 0.78814.
He has already earned $8 5 times, so we know that he has 8×5=$40. 88-40=48, so he needs $48 more. 48÷8=6, so he needs to walk the neighbour's dog 6 more times to earn that extra $48
The second one, your welcome
