The black graph is the graph of y=f(x). Choose the equation for the red graph.<br> Please help!!
yan [13]

Answer:

B

Step-by-step explanation:

The black graph is the graph of y=f(x).

The red graph is the reflection of the black graph across the y-axis.

A. y=f(x-1) determines the translation of the graph y=f(x) one unit to the right.

B. y=f\left(\dfrac{x}{-1}\right) determines the reflection of the graph y=f(x) across the y-axis.

C. y-1=f(x),\ y=f(x)+1 determines the translation of the graph y=f(x) one unit up.

D. \dfrac{y}{-1}=f(x),\ y=-f(x) determines the reflection of the graph y=f(x) across the y-axis.

Demetrius deposits $120 iinto his account. One week later he withdraws $36. Write an addition sentence to represent this situati
Zolol [24]

Answer:

Demetrius's account is $84 higher after the two transactions

Step-by-step explanation:

Let

x -----> original amount in Demetrius's account

y ----> amount in Demetrius's account after the deposit and the withdraws

we know that

The amount in Demetrius's account after the two transactions must be equal to the original amount in Demetrius's account plus the deposit minus the withdraws

so

y=x+120-36

y=x+\$84

therefore

Demetrius's account is $84 higher after the two transactions

Answer:

The 80% confidence interval for difference between two means is (0.85, 1.55).

Step-by-step explanation:

The (1 - <em>α</em>) % confidence interval for difference between two means is:

CI=(\bar x_{1}-\bar x_{2})\pm t_{\alpha/2,(n_{1}+n_{2}-2)}\times SE_{\bar x_{1}-\bar x_{2}}

Given:

\bar x_{1}=M_{1}=6.1\\\bar x_{2}=M_{2}=4.9\\SE_{\bar x_{1}-\bar x_{2}}=0.25

Confidence level = 80%

t_{\alpha/2, (n_{1}+n_{2}-2)}=t_{0.20/2, (5+5-2)}=t_{0.10,8}=1.397

*Use a <em>t</em>-table for the critical value.

Compute the 80% confidence interval for difference between two means as follows:

CI=(6.1-4.9)\pm 1.397\times 0.25\\=1.2\pm 0.34925\\=(0.85075, 1.54925)\\\approx(0.85, 1.55)

Thus, the 80% confidence interval for difference between two means is (0.85, 1.55).
