determine the area of a trapezoid the length of the midline of 14 centimeters and the length of the height of 8 centimeters

emmainna [20.7K]

Answer:

Area = 112cm^2

Step-by-step explanation:

Area = (a + b)*h / 2

M = (a + b) / 2

14 = (a + b) /

2*14 = a + b

28 = a + b

Area = 28*8 / 2

Area = 112 cm^2

Answer:

Coupon B

Step-by-step explanation:

Given

$Price = \$450$

$Coupon\ A = \$80$

$Coupon\ B = 20.5\%$

Required

Which coupon is better

From the question, we have:

$Coupon\ A = \$80$

$Coupon\ B = 20.5\%$

Coupon B means that:

$Coupon\ B = 20.5\% * \$450$

$Coupon\ B = 0.205 * \$450$

$Coupon\ B = \$92.25$

By comparison:

Coupon B gives him a better buy because: $\$92.25 > \$80$

A researcher randomly assigned N = 16 rodents to experience one of four levels of shock (n = 4 per group) following the illumina

Umnica [9.8K]

Answer:

The hypothesis should be retained

Step-by-step explanation:

We are given:

N= 16

n = 4

$SS_B_G = 24$

$SS_E = 48$

Level of significance, a = 0.05

From the given data, our ANOVA table will be:

$----Source: Between---- Residual---$

$------DF:n-1=> 4-1=3------N-n=>16-4=12$

$------SS: SS_B_G = 24---- SS_E =48$

$----MS: MS_B_G = 8----MS_E=48/12=4$

Note: proper ANOVA table is attached

The statistic will be written as:

$TS = \frac{MS_B_G}{MS_E} ~ F_n_-_1, _N_-_n$

T = 8/4 = 2

Therefore

$F_n_-_1, _N_-_n, _a$

$=> F_3,_1_2,_ 0_._0_0_5 = 3.490$

The hypothesis should be retained, because we no know that the statistic is in the acceptance area.
