Answer:

Connie started with $25 in her savings account.

Step-by-step explanation:

The y-intercept is the value of the function at time zero.

At x = 0, which is week zero, when Connie opened the account, the y value is 25. That means she opened the account with $25.

Answer: $25

Answer:

Requirements are computed below.

Step-by-step explanation:

For ABC analysis:

Step1: Calculate the total value of each item.

SKU Number of Items Value ($/item) Value of the product ($)

A 220 67 14740

B 225 3 675

C 245 21 5145

D 145 7 1015

E 230 26 5980

F 240 83 19920

Step2: Reorganize the table on the basis of total value in descending order, & calculate % share of total value of investment and cumulative % share of total value of investment.

SKU Number of Items Value ($/item) Value of the product ($) % of Total value Cumulative % of total value Segment

F 240 83 19920 41.96 41.96 A

A 220 67 14740 31.05 73.01 A

E 230 26 5980 12.60 85.60 B

C 245 21 5145 10.84 96.44 B

D 145 7 1015 2.14 98.58 C

B 225 3 675 1.42 100.00 C

----------

% of total number of items in segment B = (230+245)/1305 = 36.4%

% of total value of inventory in segment B = (12.6 + 10.4)/100 = 23.43%

% of the total weight of inventory in segment B = (9660+14700)/67795 = 35.93%

SKU Number of Items Value ($/item) Weight (lb/item) Total weight

A 220 67 52 11440

B 225 3 59 13275

C 245 21 60 14700

D 145 7 48 6960

E 230 26 42 9660

F 240 83 49 11760

Prove that.....cos^2α(cosec^2α-cot^2α)=cos^2α

Dafna1 [17]

Step-by-step explanation:

We must prove that

cos²a(csc²a-cot²a) = cos²a

If we look at both sides, we can see that we have cos²a * something = cos²a. Therefore, if we can get that something to equal 1, we have our proof. In this case, that something is csc²a-cot²a. Using this information, we can work from within the parenthesis and go from there.

We can start by expanding the items in the parenthesis. Taking that csc(x) = 1/sin(x) and cot(a) = cos(x)/sin(x), we can say that

cos²a(csc²a-cot²a) = cos²a(1/sin²a - cos²a/sin²a). Because both items in the parenthesis have a denominator of sin²a, we can subtract cos²a from 1 to get

cos²a(1/sin²a - cos²a/sin²a)= cos²a((1-cos²a)/sin²a))

Next, we know that cos²a+sin²a=1, so 1-cos²a = sin²a. Plugging that in, we get

cos²a((1-cos²a)/sin²a)) = cos²a(sin²a/sin²a)

= cos²a(1)

= cos²a

Consider the following regression output where the dependent variable is testscores and the two explanatory variables are the st

jeyben [28]

Answer:

The correct option is (A).

Step-by-step explanation:

The multiple linear regression equation is given by, $y=\alpha +\beta _{1} x_{1}+\beta _{2}x_{2}$ , where α = constant and β $_{i}$ = slope coefficients of regression line.

To test if there is a important relationship amid X $_{i}$ and Y, we use the t-statistic test.

The t-statistic for regression coefficient analysis is given by,

$t=\frac{\beta_{i}}{S.E._{\beta_{i}}}$

The regression equation for test scores dependent upon the two explanatory variables, the student-teacher ratio and the percent of English learners is:

$\text{TestScore} = 698.9 - 1.10 \text{ STR} - 0.650 \text{ PctEL}$

A t-test for the significance of the regression coefficient of variable student-teacher ratio (STR) is conducted.

The test statistic is found to be, t = 2.56.

The regression coefficient of variable STR is, 1.10.

Compute the standard error of the regression coefficient as follows:

$t=\frac{\beta_{i}}{S.E._{\beta_{i}}}$

$S.E._{\beta_{i}}=\frac{\beta_{i}}{t}$

$=\frac{1.10}{2.56}\\\\=0.4296875\\\\\approx 0.43$

The standard error of the regression coefficient is 0.43.

Thus, the correct option is (A).
