At a garden shop, a customer buys 5 geraniums and 4 lilies for $48. Another customer pays $58 for 4 geraniums and 6 lilies. Writ

masha68 [24]

Answer:

A lily costs $7 and a geranium $4.

Step-by-step explanation:

From the question, we can write two equations. let the number of lilies be l and the number of geraniums be g, then:

5 g + 4 l = 48

4 g + 6 l = 58

Multiply the first equation by 4 and the second by 5, the number of lilies in the other gives:

20 g + 16 l = 192

20 g + 30 l = 290

Subtract the first equation from the second gives:

14 l = 98 which dividing by 14 gives l = 7

Substituting the value l = 7 in the first equation gives:

5 g + 28 = 48

Subtract 20 from both sides gives:

5 g = 20 divide by 5 gives g = 4

So, a lily costs $7 and a geranium costs $4.

The numerical value of the variance a. is negative if the mean is negative. b. is always larger than the numerical value of the

Snowcat [4.5K]

Answer:

Step-by-step explanation:

Variance is the sum of squares of all items x from mean. i.e

Variance = $\Sigma (x-xbar)^2$

Being the sum of squares variance can never be negative irrespective of mean being negative.

Std deviation is the square root of variances. This will thus be less than variance if variance >1 other wise std deviation will be bigger than variance.

Hence option d is right.

sveticcg [70]

Answer:

<h3>The volume of the prism is cubic $\frac{105}{512}$ centimeters.</h3><h3>Step-by-step explanation:</h3><h3>Given that a rectangular prism has the following dimensions:</h3><h3> $length, l=\frac{3}{8}cm \\\\width, w=\frac{5}{8}cm \\\\height, h=\frac{7}{8}$ </h3><h3>We know that a rectangular prism of length 'l', width 'w' and height 'h' is given by</h3><h3> $V=w*h *l.$ </h3><h3>Therefore, the volume of the given prism will be</h3><h3> $V\\\\=w*h*l\\\\=\frac{3}{8}*\frac{5}{8}*\frac{7}{8} \\\\=\frac{105}{512}cm^{3}.$ </h3><h3>Thus, the volume of the prism is $\frac{105}{512}$ cubic centimetres.</h3>

Michelle borrows a total of $2500 in student loans from two lenders. One charges 4.4% simple interest and the other charges

Inessa [10]

The amount borrowed from the the lender that charges 4.4% interest is $1000.

The amount borrowed from the the lender that charges 5.7% interest is $1500.

<h3>What are the linear equations that can be derived from the question?</h3>

a + b = $2500 equation 1

0.088a + 0.114b = $246 equation 2

Where:

a = amount borrowed from the lender that charges 4.4% interest

b = amount borrowed from the lender that charges 5.7% interest

<h3>How much was borrowed from the lender that charges 5.7% interest?</h3>

Multiply equation 1 by 0.114

0.114a + 0.114b = 285 equation 3

Subtract equation 2 from equation 3

39 = 0.026b

b = $1500

<h3>How much was borrowed from the lender that charges 4.4% interest?</h3>

Substitute for b in equation 1

a + $1500 = $2500

a = $2500 - $1500

a = $1000
