There are three exams in your linear algebra class, and you theorize that your score in each exam (out of 100) will be numerical

Romashka [77]

Answer:

a) 40 hours

b) 60 hours

C) 100 hours

Step-by-step explanation:

0.2a + 0.3b+0.5c = 76

Hence: 0.2* (0.2 λ) +0.3*(0.3 λ )+0.5*(0.5 λ ) = 76

0.38 λ =76

λ = 76/0.38 =200

Thus : 40, 60, 100

Bezzdna [24]

Given :

You order 1.5 pounds of turkey at the deli.

You will accept the turkey if its weight is between 1.54 and 1.46 pounds.

To Find :

What absolute value inequality can be used to describe the tolerance of the weight of the turkey.

Solution :

It is given that the weight cannot be less that 1.46 pounds.

So, mathematical equation is :

x ≥ 1.46 .....1 )

Also, weight cannot be greater than 1.54 pounds.

x ≤ 1.54 ......2)

Combining equation 1 and 2 we get :

1.46 ≤ x ≤ 1.54

Hence, this is the required solution.

Is there a way to simplify the process of plugging in factors through synthetic division to find the zeros of a polynomial? I am

Iteru [2.4K]

Yes you can use the discriminant of a quadratic/polynomial. For instance, if
$b^2 - 4ac = 0$ there is one real root. If $b^2 - 4ac > 0$ there are two real roots and i $b^2 - 4ac < 0$ there are no real roots

The discriminant comes from the quadratic equation, which is the following.
$x = \frac{-b \pm \sqrt{b^2-4ac}}{2a}$

Answer:

Looking for four values or answers

(A) 5.05

(B) 13

(C) $254,140.33

(D) $254,145.38

Step-by-step explanation:

(A) The value of the margin of error.

Using a 90% confidence level or 0.10 alpha level,

1 - alpha = 1 - 0.10 = 0.90

The degrees of freedom = n - 1 = 14 - 1 = 13

Using the t table, 0.90 under 13 is 1.350

Sample size divided by √n is equal to

14/√14 = 3.742

1.35 × 3.742 = 5.05

(B) 13 degrees of freedom

(C) To find the lower and upper limits, you find the mean value first and then subtract / add to half of the margin of error which is 5.05÷2 = 2.525

Adding the 14 values together, you have $3,558,000

Dividing by 14 to get the mean;

Mean = $254,142.8571

Lower Limit: $254,140.33

Upper Limit: $254,145.38
