the question does not present the options, but this does not interfere with the resolution

let

x-------> the length of the garden

y-------> the width of the garden

A-------> Area of the garden

we know that

A=x*y

A=120 ft²

for x=12 ft

120=12*y-----------------> y=10 ft

but

<span>the length of the garden to be more than 12 feet
so
</span>

x > 12 ft

therefore

y < 10 ft

Hence

the answer is

The width of the garden <span>must be less than 10 ft  (width < 10 ft)</span>

PSYCHO15rus [73]

Answer:

At 0.05 level of significance, there is no difference in the mean number of larvae per stem. This supports the scientist's claim.

(d) H0: MeanMalathion - MeanNoMalathion equals 0

H1: MeanMalathion - MeanNoMalathion not equals 0

Step-by-step explanation:

Test statistic (t) = (mean 1 - mean 2) ÷ sqrt[pooled variance (1/n1 + 1/n2)]

Let the difference between the two means be x and the pooled variance be y

n1 = 5, n2 = 12

t = x ÷ sqrt[y(1/5 + 1/12)] = x ÷ sqrt(0.283y) = x ÷ 0.532√y = 1.88x/√y

Assuming the ratio of x to √y is 0.5

t = 1.88×0.5 = 0.94

n1 + n2 = 5 + 12 = 17

degree of freedom = n1 + n2 - 2 = 17 - 2 = 15

significance level = 0.05 = 5%

critical value corresponding to 15 degrees of freedom and 5% confidence interval is 2.131

The test is a two-tailed test because the alternate hypothesis is expressed using not equal to.

The region of no rejection of the null hypothesis lies between -2.131 and 2.131

Conclusion

Fail to reject the null hypothesis because the test statistic 0.94 falls within the region bounded by the critical values.

The scientist's claim is right.

A null hypothesis is a statement from a population parameter which is either rejected or accepted (fail to reject) upon testing. It is expressed using the equality sign.

An alternate hypothesis is also a statement from a population parameter which negates the null hypothesis and is accepted if the null hypothesis is rejected. It is expressed using any of the inequality signs.

What is the area of the trapezoid
Xelga [282]
Short answer: B
Remark

A 45 degree angle means that the height is the same length as part of the base. But which part?

Givens
b1 = 9 feet
b2 = 23 feet
and the 45 degree angle on the right.


Determine the height.
The part of the base that is associated with the 45 degree angle is found by subtracting b1 from b2
b2 - b1 = 23 - 9 = 14
So 14 is also the height

Find the Area
A = 1/2 (b1 + b2)*h
b1 = 9
b2 = 23
h = 14

Area = 1/2(9 + 23) * 14
Area = 1/2 (32) * 14
Area = 16 * 14
Area = 224 <<<< answer
