Mariam is making
ira [324]

Answer:

  no

Step-by-step explanation:

A trapezoid is shown, not a bag. If we assume that this shape is supposed to be the front of the bag, Mariam does NOT have enough pink fabric to make the front of the bag from pink fabric.

The area of the trapezoid shown is ...

  A = (1/2)(b1 +b2)h

  A = (1/2)(9 in + 8 in)(15 in) = 127.5 in^2

This area is larger than the amount of fabric Mariam has, so she does not have enough.

Ignacio earns 5 percent simple interest annually on his savings account. How much interest will he earn each month on $1250? sim
gulaghasi [49]
I=PRT
I=interest
P=principal
R=rate in decimal
T=time in years

we want to find how much he earns when he invests 1250, on 5%, and how much per month, or 1/12 years
P=1250
R=0.05
T=1/12

I=1250(0.05)*(1/12)
I=62.5/12
I=5.2083333
round to nearest cent
I=$5.21

about $5.21 per month

A random variable x has a Normal distribution with an unknown mean and a standard deviation of 12. Suppose that we take a random
Zielflug [23.3K]

Answer: The 95% confidence interval for the mean of x is (94.08, 101.92) .

Step-by-step explanation:

We are given that ,

A random variable x has a Normal distribution with an unknown mean and a standard deviation of 12.

i.e. \sigma= 12

Also, it is given that , Sample mean \overline{x}=98 having sample size : n= 36

For 95% confidence ,

Significance level : \alpha=1-0.95=0.05

By using the z-value table , the two-tailed critical value for 95% Confidence interval :

z_{\alpha/2}=z_{0.025}=1.96

We know that the confidence interval for unknown population mean(\mu) is given by :-

\overline{x}\pm z_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}

, where \overline{x} = Sample mean

\sigma = Population standard deviation

z_{\alpha/2} = Critical z-value.

Substitute all the given values, then the required confidence interval will be :

98\pm (1.96)\dfrac{12}{\sqrt{36}}

=98\pm (1.96)\dfrac{12}{6}

=98\pm (1.96)(2)

=98\pm 3.92=(98-3.92,\ 98+3.92)\\\\=( 94.08,\ 101.92)

Therefore, the 95% confidence interval for the mean of x is (94.08, 101.92) .
